Improvements in biotechnology have helped advance the fields of medicine, agriculture, and forensics. Many people are concerned with the ethical limits that should be placed on much of the research for future advances. An example can be seen when discussing the human cloning. There are two types of cloning, reproductive and therapeutic.
Reproductive cloning is considered unethical and there are laws preventing it. However, human therapeutic cloning is not considered as unethical. Which of the following questions is a likely to address the difference of opinion in many people concerning cloning? (8a-DOK 2)
Should be embryos destroyed in the process of therapeutic cloning?
Is cloning beneficial to produce stem cells that lead to medical benefits for many?

A farmer is presented with two options. One option is to use a genetically modified corn plant and the other option is to use a non-genetically modified corn plant. Which of the following questions would a farmer ask to decide which corn plant to use? (8a-DOK 2)
“If I use GMO corn, am I able to plant them earlier in the year and grow them later into the year
because they are more resistant to colder temperatures?”
“Will I be able to increase the amount of corn I grow due to each plant producing more?”
“Will I be able to sell my corn for a higher price to earn a higher profit because it is a GMO corn?”
“Will I be able to use less insecticide because the corn will be more insect resistant?”
Some scientists hypothesize that genetically engineering salmon to increase their size and rate of growth can help meet human demands for protein. Which of these questions addresses the biggest concern scientists should research before releasing the genetically engineered salmon into the wild? (8a1-DOK2)
Will genetically engineered salmon have a less desirable taste than wild salmon?
Will the genetically engineered salmon introduce modified genes into the wild salmon population?
Will the genetically engineered salmon not grow as well in the wild as they do in inland facilities?
Will the genetically engineered salmon be able to reproduce as well in the wild as the wild population of salmon?
Which question may be asked and researched by someone who is arguing against the use of genetically modified crops? (8a1-DOK2)
Have genetically modified crops allowed farmers to save money on insecticides and pesticides?
Will genetically modified crops reduce the amount of land and energy used by farms because they have high yields?
Have genetically modified crops shown improvements in nutrition for consumers compared to non-genetically modified crops?
Will the prices of crops increase because the seeds for genetically modified crops are more expensive and this may drive small farmers out of business?

Which of the following statements is not one of the ideas Lamarck had regarding evolution? (9a-DOK 1)
Lamarck believed organisms could acquire adaptations out of need.
Lamarck concluded if an organism did not use a trait, it would be lost over time due to disuse.
Lamarck thought traits acquired in an organism’s lifetime would be passed down to offspring,
Lamarck understood that natural variations occurred in populations and nature selected for or against these adaptations
A group of students is asking questions about the differences and similarities between the theories of evolution proposed by Lamarck and Darwin. They decide to create a Venn diagram with Lamarck’s ideas on one side and Darwin’s on the other. The shaded area in the middle represents ideas they had in common. (9a-DOK 2)
Which of the following questions should be asked if thinking from Lamark’s theories on evolution, and therefore be placed in the Lamarck only side of the Venn Diagram?
Why do organisms evolve over time?
There are variations in populations. What causes those that are best adapted to live and reproduce successfully?
How do organisms over time, that are best adapted l survive to pass along these traits to their offspring, resulting in more individuals each generation having the desired trait?
How can organisms can acquire traits they need and then pass down these acquired characteristics that they had obtained in their lifetime to their offspring?
The images below show two separate theories of how organisms evolve. Which question below directly corresponds to whether Lamarck or Darwin are correct about their theories of the mechanisms of evolution? (9a-DOK 3)
Why don’t the shorter neck giraffes feed on grasses and lower vegetation?
How would the shorter necked giraffes in Lamarck’s theory survive to reproduce and pass on the “need” for longer necks if they were unable to reach food?
Why won’t the taller necked giraffes in Darwin’s theory provide assistance to the shorter giraffes since they are the same species?
Will the smaller giraffes be more adapted to hide from predators since they wouldn’t be visible from greater distances?
Which questions by a student would lead to a better understanding of the difference between the theories of Darwin and Lamarck? (9a-DOK1)
Which scientist's theory came first?
Which scientist’s theory requires genetic diversity?
Which scientist’s theory involves the inheritance of useful traits?
Which scientist’s theory involves change in organisms over time?
There is a multitude of evidence that supports how life has changed over time due to variation in the gene pool of different species. Which of the following choices below represents a scientific theory that explains these changes? (9a-DOK2)
As environments and ecosystems change over time, the gene pool also changes because organisms must adapt to survive and those that acquire suitable traits are more likely to survive and reproduce.
As environments and ecosystems change over time, the gene pool also changes because organisms that already have the best suited traits are more likely to survive and reproduce.
Because the environments and ecosystems show little change over time, organisms are already adapted for surviving in their given habitats for which they are made.
Because the environments and ecosystem show little change of time, the organisms that choose to adapt to different environments will migrate and become suited for new habitats.
Which argument correctly supports why a population with high genetic variation would have a better chance of survival than a population with low genetic variation? (9b-DOK2)
Populations with high genetic variation would have a high number of individuals. This high number of members would make them safer from predators while lessening the chances of inbreeding.
Populations with high genetic variation would have a low number of members. This low number of members would make them safer from diseases while lessening the chances of inbreeding.
Populations with high genetic variation have a higher chance of survival. This is due to the likelihood that some members of the population will survive an environmental pressure and reproduce.
Populations with high genetic variation have a higher chance of survival. This is due to the likelihood that some members of the population will survive an environmental pressure and help the others.

An evolutionary biologist conducts a longitudinal study on a population of foxes for 30 years. He notes that over the years, the population of foxes in the area remains fairly consistent at around 10 to 15 foxes per 5 square acres of land. His observations and records show that around half of the pups (baby foxes) born do not survive to reproductive age. He concludes that this is due to competition for food and shelter, occasionally harsh weather, and human impact. The fox population typically seems to recover well, even after difficult years. Then, in a single generation, only 15% of the foxes lived to see reproductive age, which could potentially have a drastic impact on the population for several years. After further investigation of the carcasses of the young foxes, the biologist noted a parasitic mite infestation in the dead foxes. Which of the following is a likely claim the biologist could make regarding what he observed and recorded? (9b-DOK2)
Foxes are more likely to survive if there are fewer foxes per square acre.
Foxes are less likely to survive if there are fewer foxes per square acre.
Foxes are more likely to survive if they are less prone to mite infestations
Foxes are less likely to survive if they are less prone to mite infestations
Two students are working on an “Evidence for Evolution” lab for their biology class. As the two are working on completing some of the post-lab questions, they start to get into a conversation about the different forms of evidence. Student A claims that the fossil record is the most reliable form of evidence while Student B claims that comparative morphology is the most reliable. Consider the two students’ claims and select which student, if either, is correct in their argument. (9b-DOK3)
Student A is correct because the fossil record is permanent and cannot change. So, as scientists discover more fossils, these structures fill in all of the gaps of the evolutionary timeline.
Student B is correct because the most accurate way we can tell that organisms are related are by looking at present day structures and their similarities and differences from each other. The more organisms that scientists can compare in the modern day, gives explicit information about structures of the past.
Neither student is correct. The most reliable form of evidence for evolution is embryology. Since all plants and animals are made of cells, the cells that are present at the first stages of development contain the most information about all organisms pasts.
Neither student is correct. The most reliable form of evidence for evolution is genetic comparison. At the genomic level, scientists are able to better understand how variation leads to evolutionary change and adaptation.
The model below shows the embryonic development of 3 species of invertebrates. These species are marine animals that are believed to be around 533 million years old.
Use the model to answer the question below.
Which argument for the relationship between these species is best supported by the model?(9b-DOK3)
Only the P. falva and S. kowalevskii have common ancestry they have similar body structures at point G and point N.
Only the P. falva and Echnoid have common ancestry they have similar structures at point L and point S.
It is not possible for any of these organisms to have common ancestry as they all have variations in their embryological development starting at point D, point K, and point R.
It is possible for all organisms to have common ancestry as they all have similar structures at point C, point J, and point Q.
Variation in a population is increased by which of the following? (9b-DOK 1)
Inbreeding
Emigration
Mutations
Genetic Drift
Darwin’s Theory of Natural Selection states that there is a struggle to survive as organisms compete for resources and try to avoid predation. Over time, the organisms best adapted will survive and pass their traits on to offspring. Which of the following is the best explanation of the role mutations play in natural selection? (9b-DOK 1)
Mutations provide variation within a population and environmental pressures select for or against these adaptations.
Mutations are always harmful and organisms with mutations will be selected against, leaving those that are best adapted to pass their traits on to offspring.
All mutations in somatic cells are passed on to offspring and over time as mutations are passed down through generations, populations will change.
Mutations that occur in gametes are always fatal to offspring which prevents new traits from entering into a gene pool.
The arctic tundra has low sunlight, cold temperatures, and little rainfall. Although plants need sunlight and water for photosynthesis, they survive these harsh conditions by having small leaves to reduce water loss and flowers that grow quickly once summer begins. They also grow in clusters to prevent damage by cold and snow. Which of the following statements best explains how plants in the arctic tundra have evolved with these adaptations? (9b-DOK 2)
Organisms that reproduce sexually tend to have high genetic diversity. This genetic diversity results in a range of phenoptypes. This range of phenotypes increases the likelihood of extreme phenotypes in the face of environmental pressures. Both extremes in this examples demonstrate this.

Organisms that reproduce sexually tend to have high genetic diversity. This genetic diversity results in a range of phenoptypes. This range of phenotypes increases the likelihood of competition from other species in the face of environmental pressures.
Organisms that reproduce sexually tend to have high genetic diversity. This genetic diversity results in a range of phenoptypes. This range of phenotypes increases the likelihood of survival of a species in the face of environmental pressures. The phenotype most suited for the environment will be reinforced and become more common.
The graph below shows the various rates of running speed in a prey population. Which of the following statements supports the idea that genetic variation in a population increases the chance that some individuals will survive more than others? (9b-DOK 3)
The number of prey that run at a medium rate is highest, so over time there will be an overpopulation of prey that run an average rate of speed.
Because more prey run at an average rate, more average runners will survive to pass their traits on to offspring.
Slow prey will become faster out of a need to avoid predators and there will be fewer prey that run slowly in the next generation.
Over time prey that run faster than predators will survive, which will lead to an increase in the population of fast runners over time.
Students are tasked with evaluating reproductive strategies of a worm species in a habitat they have occupied for thousands of years. Which argument best matches the advantages and disadvantages of the different strategies? (9c-DOK1)
Sexual reproduction is best in this scenario, It would provide genetic diversity for the worms allowing them to be attract mates better.
Sexual reproduction is best in this scenario, It would provide genetic diversity for the worms allowing them to grow larger.
Asexual reproduction is best in this scenario, since they would need new traits in the established habitat and would not need to expend energy to migrate to a new habitat.
Asexual reproduction is best in this scenario, since they do not need new traits in the established habitat and would not need to expend energy finding a mate.
When discussing how reproduction aids in survival and evolution, 2 students are arguing about the advantages and disadvantages of each. Student one argues that because sexual reproduction leads to greater diversity, and therefore more opportunities for natural selection, organisms that reproduce asexually will eventually go extinct. Student 2 disagrees and argues that asexual organisms will not go extinct. Which argument below will best support Student 2’s stance? (9c-DOK2)
Organisms that reproduce asexually still have opportunities for genetic diversity through processes such as crossing over.
Organisms that reproduce asexually can better learn from the environments and acquire traits need for survival.
Organisms that reproduce asexually still have opportunities for genetic diversity through processes such as random mutations.
Organisms that reproduce asexually take more time to reproduce, thus ensuring the traits for survival are optimal for survival.
Different reproductive strategies can affect how organisms evolve complex structure over millions of years. For example, some argue that eukaryotes are more diverse and have more complex structures than prokaryotes because of reproductive strategies used. Which of the following statements support this argument? (9c-DOK2)
Because many eukaryotes reproduce asexually, they have a much shorter generation time.
Because many eukaryotes reproduce sexually, they have more diversity through processes such as random fertilization.
Because prokaryotes reproduce asexually, they have more time to acquire features needed for survival.
Because prokaryotes reproduce sexually, they can become more complex overtime as a result of diversity.
The model of the fossil record below represents changes in mollusks over millions of years. (10b-DOK2)
Which argument is best supported by the model?
The mollusks were well adapted to their stable environment. A large, sudden change occurred in their environment. After the change, the mollusks with the bigger shells were better adapted for the new environment.
The mollusks were well adapted to their stable environment. The mollusks hybridized with a smaller species of mollusk. A new species of mollusk with a bigger shell resulted.
The mollusks were not well adapted to their environment. The length of the mollusks’ shells changed gradually over time. The mollusks in the original population that had small shells died over a period of many years.
The mollusks were well adapted to their environment. Humans introduced a new species of mollusk that was not adapted to this environment. The introduced mollusk out competed the native mollusk species.
The data table below shows the number of individuals in a lizard population exhibiting certain traits before and after a ten-year drought.

Smaller-bodied lizards seem to have been naturally selected for by the drought conditions.
Green-skinned lizards seem to have been naturally selected for by the drought conditions.
Brown-skinned lizards seem to have been selected against by the drought conditions.
The graph below shows the number of MRSA (Methicillin-Resistant Staphylococcus Aureus) cases from 1995-2003.
Which mechanism of evolution most likely explains the increase in the number of bacteria that are resistant to the antibiotic methicillin? (10b2-DOK 1)
A small population of the original number of resistant bacteria resulting in genetic drift.
A DNA mutation that allows for antibiotic resistance
The movement of nonresistant bacteria into the community.
Asexual reproduction of the bacteria.
The graph below models how the population of bedbugs increased in New York City due to what was referred to in the graph as the “misuse of pesticides.”
What do you expect the trend to be by the end of september, and what is the best explanation for this trend? (10b2-DOK 2)
There will be some decreases, but an overall increase in bedbug posts in September. Bed bugs found new ecological niches to fill as the pesticide killed other insects.
There will be some increases, but an overall decrease in bedbug posts in September. This will happen because genetic variation existed in the bed bug population and over time the bed bugs with genes for pesticide resistance survived and reproduced.

A scientist has designed a controlled experiment to look at the way a species of bacteria referred to as MM294 grows in the presence of various amounts of antibiotic. The image shows an agar plate with no antibiotic at the top of the plate and the most antibiotic at the bottom of the plate 24 hours after the experiment was set up.
A person who is infected with the bacteria MM294 is instructed by a doctor to take the antibiotic used in this experiment for ten days. The individual takes the antibiotic for only three days and then stops taking the antibiotic because he is feeling better. How does this example demonstrate how a population of bacteria can change over time? (10b2-DOK 3)
After three days the only bacteria remaining are the ones that are genetically best adapted to resist the antibiotic. Over time these bacteria survive and reproduce asexually, making more copies of resistant bacteria.
As the bacteria are exposed to the antibiotic over the course of three days, they become stronger and better able to resist the antibiotic. The more the bacteria come in contact with the antibiotic, the more immune they become to it.
Because bacteria reproduce through binary fission they become more genetically diverse. As they multiply over three days, more and more variations of the strands of bacteria are produced which makes the species better able to survive.
The antibiotic causes a mutation in the DNA of the bacteria that allows the bacteria to resist the antibiotic. The new bacteria reproduce and pass their traits on to offspring.
Students were tasked with developing a model of how pesticide resistance is developed in population of farming pests. Each student submitted the scenario they would model to their professor. Which student’s model would be most useful in demonstrating how pesticide resistance develops in a population? (10b2-DOK3)
Student A proposes a model showing how the quantity of pesticide used compares to population size after breeding season for the pests, and how this correlates with rainfall.
Student B proposes a model showing how the quantity of pesticide used, compares to population size after breeding season for the pests, and how this correlates with average temperature.
Student C proposes to model the application of pesticides and how before and after each application this affects the ratio of phenotypes in each generation and the pest population size after each application.
Student D proposes to model the application of pesticides and how before and after each application this affects the ratio of phenotypes in each generation and the growth of the crops after each application.
The graph below shows the number of pesticide resistant species for six different types of pesticide over a fifty year time span.
What is the best explanation for what is occurring to the pest population over this period of time? (10b2-DOK3)
As the pests were exposed to various types of pesticides, many died, but those that survived acquired resistance to the pesticide and were able to reproduce and pass on their genes. Over time, pests became more and more resistant to the pesticide.
As the pests were exposed to various types of pesticides, many died, but those that survived had genes making them resistant to the pesticide and were able to reproduce and pass on their genes. Over time, pests became more and more resistant to the pesticide.
As the pests were exposed to various types of pesticides, many died, but those that survived had genes making them resistant to the pesticide and were able to reproduce and pass on their genes. Over time, pests became less and less resistant to the pesticide.
As the pests were exposed to various types of pesticides, many died, but those that survived then acquired resistance to the pesticide and were able to reproduce and pass on their genes. Over time, pests became less and less resistant to the pesticide
One of the pieces of evidence for evolution that Charles Darwin collected on his travels aboard the HMS Beagle was the observation of fossils of extinct animals and similar but noticeably different current species. Giant ground sloth fossils were very similar in shape to the bones of sloths that inhabited the regions of South America he was exploring. The main difference was the size, the ground sloth fossils were significantly larger than the bones of the sloths he captured alive. What was a conclusion that Darwin was able to arrive to based on this piece of evidence? (11a-DOK 1)
The fossils of the ground sloth are not related at all to the bones of the captured sloths that currently reside in
South America.
The fossils of the ground sloth are from the same species as the captured sloths that currently reside in South America, just a larger example of the species.
The fossils of the ground sloth are the ancestors to the captured sloths that currently reside in South America.
The fossils of the ground sloth are from the same species as the captured sloths that currently reside in South America.
It has taken millions of years for the ancestors of whales to change into what we know today, as indicated in the diagram above. Based on your knowledge of evolution, which of the following is a reasonable explanation of why the organisms in the diagram changed over the 25 million years indicated? (11a-DOK 2)
As the environment changed the food sources became more difficult to obtain so characteristics that allowed the organisms to hunt in an aquatic environment became more advantageous.
As the environment changed the temperature became too hot and the organisms began to move to a more aquatic environment to keep cool.
As the environment changed the food sources became more difficult to obtain so the organisms decided to change their characteristics to ones that would be beneficial when hunting in an aquatic environment.
As the environment changed the predators on land became better adapted to hunting the whales ancestors forcing them to live in more aquatic environments.
42. Transitional species are species important in helping scientists determine the evolutionary path that species have taken over long periods of time. Lobe-finned fishes are the ancestors of amphibians and have fossils that are found in rocks that are at least 380 million years old. Fossils of the oldest amphibian-like vertebrate animals with true legs and lungs are found in rocks that are approximately 363 million years old. Paleontologists have found a sample of rock that is approximately 370 million years old which contains what seems to be a link between lobe-finned fishes and amphibians. Which of the following is a characteristic that you would not expect to see in this transitional fossil? (11a-DOK 3)
Skeletal structures that indicate the development of legs
An intermediate structure between lungs and gills
Teeth that are intermediate to the lobe-finned fishes and amphibians
A neck that is more flexible than lobe-finned fishes
The map below shows the seas that covered North America during part of the Cretaceous period, approximately 100 million years ago.

Many of them could swim.
Fewer species existed at the time.
All of them could survive underwater.
They were adapted to live in different habitats.
Scientist have noted that following large scale extinction events new species have developed in quick succession. This process is called punctuated equilibrium. Which question below would lead to a better understanding of why this happens? (11c-DOK1)
Does the availability of niches provide opportunities for species to adapt and differentiate?
Does the availability of niches mean that those niches are not suited for usage by living species?
Does an explosion of diversity indicate a change in carrying capacity of an ecosystem?
Does an explosion of diversity indicate organisms were adapted to occupied niches and waiting for them to open?
A scientist observes two species of lizards living on opposite sides of a mountain range. The scientist attempts to breed the two species together but is not successful. Which question should the scientist research to determine how the speciation occurred? (11c-DOK2)
Did the lizards go through speciation due to competition for resources?
Did the lizards go through speciation due to geographic barriers preventing interbreeding?
Did the lizards go through speciation due to coevolution because of the close relationship between them?
Did the lizards go through speciation due to genetic equilibrium within the population?
A significant shift in the environmental conditions over a very short period of time caused most groups of dinosaurs to become extinct because of their inability to adapt fast enough. This allowed for a variety of niches to open providing current organisms new opportunities. Mammals were one group of organisms that took advantage of this environmental change, filling niches that were unoccupied and eventually developing new species that were specifically adapted to their particular environment. Which of the following is a term that most correctly describes this process? (11c-DOK 1)
Adaptive radiation
Gradualism
Convergent Evolution
Genetic Drift
The Galapagos Islands are a chain of volcanic islands that are off the coast of Ecuador in South America. The islands are inhabited by organisms that are similar to the organisms on the mainland of South America but they have specific characteristics that set them apart. One of the most famous groups of organisms that has been studied has been the finches. There are at least 13 different species of ground finches found throughout the Galapagos, most likely all coming from a common ancestor that arrived from the mainland of South America in the distant past. Which of the following explanation accurately explains the variation of finches on the Galapagos islands? (11c-DOK 2)
Convergent evolution has occurred because the finches all share characteristics that are similar to the common ancestor but differ because each species occupies different niches that require different characteristics to survive.
Convergent evolution has occurred because the finches do not share characteristics that are similar to the common ancestor and differ because each species occupies different niches that require different characteristics to survive.
Divergent evolution has occurred because the finches all share characteristics that are similar to the common ancestor but differ because each species occupies different niches that require different characteristics to survive.
Divergent evolution has occurred because the finches do not share characteristics that are similar to the common ancestor and differ because each species occupies different niches that require different characteristics to survive.
The diagram below shows the several of the species of finches that are found on the Galapagos islands. Based on the differences of the finch species depicted, choose the best prediction and explanation of which species would be most successful if an extreme drought occurred over several years. (11c-DOK 3)
Finch 2 would be the most successful because it has a beak that is intermediate in length and depth allowing it to eat a variety of foods.
Finch 1 would be the most successful because it has a long and deep beak that allows it to store water for long periods of time.
Finch 1 would be the most successful because it has a long and deep beak allowing it to consume drought resistant foods.
Finch 1 would be the most successful because it is has a larger beak that allows it to consume food more quickly out competing all other species.
