A farmer is harvesting this seasons Corn to be sold. The farmer discovered Corn with darker leaves, which appear to grow well in all weather types and resist insects on their own unlike other varieties of Corn that require additional pesticides to resist insects. Pesticides are substances used to repel or control forms of animal life considered to be pests. The next season, the farmer decided to get rid of the other Corn and plans to only Dark Leaf Corn. What is a result of this farmer's action?
Select all correct answers.
An increase in genetic variation of the Corn
An increase in use of pesticides ont he farm
A decrease in Corn Production
His crops are more resistant to insects and the weather
He has decreased the genetic diversity of his corn
Researchers from the National Institutes of Health last month announced that they'd successfully transplanted hearts from genetically engineered pigs into baboons, potentially paving the way for pig-to-human organ transplants in the future.
And on May 7, genome scientist Craig Venter partnered with United Therapeutics Corp. to develop pig lungs that could be compatible with the human body.
But pigs offer more than just a potential source for organ donation. For over 30 years, scientists have been using pigs in a number of medical fields, including dermatology, cardiology and more. Recently, scientists were even able to re-grow human leg muscles using implants made of pig bladder tissue.
Why is this possible?
There is an increase in genetic mutations in organisms
Humans and pigs contain identical DNA
There is an increase in genetic variation between the two organisms
Humans and pigs contain similarities in their genetic sequence.
Some of the organelles in eukaryotic cells were once prokaryotic microbes absorbed and added to the makeup of the cell.
This is an example of?
Endosymbiotic
Exosymbiotic
Commensalism
Endoparasitism
The image above is an example of endosymbiotic theory. Why is it important.
It provides an explanation of how life today could have originated from a single cell.
It provided an explanation as to why prokaryotic cells do not have a nucleus.
It provides an explanation of how life today could have originated from a single cell.
It provides an explanation of how prokaryotic and eukaryotic cells use oxygen to work.
The image above shows both Pasteur and Redi's experiments. What is true? Select all correct answers
The experiment proved spontaneous generation is not real.
Life comes from life
Spontaneous Generation is an observable fact
Evolution can be created in chicken broth
Life was able to originate on ancient earth
The universal genetic code is a blueprint that all cells use to read DNA sequences. An organism's genetic code is written using the four bases found in DNA. They are arranged in three- letter words called codons whose sequence identifies a corresponding amino acid. The combination of these amino acids then leads to the creation of proteins. The chart below can be used with all organisms in order to identify the amino acids coded for within their DNA sequences.
What is true? Select all correct answers.
All organisms share a common genetic code
All organisms originated from a single organism.
Some organisms share a common genetic code
All organisms came from a different founder original cell.
This is not Genetic Drift. What is it?
Gene Flow
Mutation
Natural Selection
GMO's
This is Gene Flow, how do you know?
One organisms that is different joins the others, introducing new genes
The brown bugs are killing the green bugs
They are mutating into a different population
This is how the founders effect works
This is not the founders effect what is it?
Genetic Drift
Gene Flow
Natural Selection
Mutation
This is not mutation. What is it?
Natural Selection
Gene Flow
Genetic Recombination
Genetic Drift
Why can Island 1 support all three species?
It is the original populations and all three are suited to survive there.
It can't
Genetic Drift has caused them to develop identical traits for survival
Mutations have allowed all three to live together.
This theory states that species change over time, possibly becoming more complex. We track these changes through fossils and genetics as well as other disciplines. What theory is this?
Evolution
Spontaneous Generation
Extraterrestrial implantation
No theory matches that idea.
What is true about this image.
It supports the concept of Common Descent
It shows patterns of species distribution that explain organisms evolution
Shows how land masses connected and separated.
Shows support for spontaneous generation.
What is cranial capacity?
how much brain a head can hold
the size of sandhill cranes over the centuries
how much heart a body can hold
The carrying capacity of the Cranial Islands
Using the image, what questions would help students understand the trends in hominid evolution. Select all Correct Answers.
Does Cranial Capacity impact the ability to survive?
Did hominids with larger cranial capacities reproduce more frequently?
What ecological demands influenced a decline in brain capacity
How did social competition change between Australopithecus and Homosapians influence evolution
WHich of the following correctly identifies adaptation in hominids over time? (Select all correct answers)
Opposable thumbs to use tools
Increased brain size lead to language
Bipedalism (walking on two feet) allowed long distance travel
Different colored eyes to view different spectrums of light to detect danger
Greater jaw sizes allowed word pronunciation.
What is true about the image above. (check all answers that are correct)
The number of toes have reduced
Horses once had 4 bones in their feet
The timeline matches where you would expect to find the fossils in rocky layers since the oldest fossils are deeper
Horses have begun growing toes
True or False: A population of people who live near the North Pole are able to sustain their body temperatures in subzero temperatures as well as have developed lighter skin in order to more efficiently absorb vitamin D from the sun. This is the the next step in human evolution.
True
False
Two distinct populations of the same frog species live in two ponds separated by land. A violent Earthquake disrupts the land and destroys the land dividing the ponds, causing the waters to merge. The two ponds merge becoming one big pond with frogs from each population swimming around. Which answer correctly explains what evolutionary mechanism will affect the frog populations due to this flooding?
Gene flow will affect the frog populations because there will be a transfer of genes across populations.
Genetic drift will affect the frog populations because the removal of a geographic barrier will lead to migration.
Mutation will affect the frog populations because the hurricane will cause the DNA to change to adapt to the new environment.
Natural selection will affect the frog populations because the fish will only reproduce with individuals from their original populations.
Tasmania is an island state off the coast of Australia. It has many animal species that are not found anywhere else in the world, such as the Tasmanian Devil and The Eastern Quoll (possibly extinct). Which of the following would be a result of genetic drift event that impacted the small Tasmanian devil population after many generation & how do we know this could happen?
The tasmanian devil may become extinct due to limited genetic variation prohibiting natural selection. We know this is possible because it happened to the Eastern Quoll.
A new species of tasmanian devil may appear, which is what happened to the Eastern Quoll
The tasmanian devil may reproduce with other animals to create a more diverse and stronger fertile species
Geographic Isolation allows for new traits to appear helping the organism survive.
The image above shows speciation. What is happening?
A boundary is formed splitting a population, over time the populations develop different traits for survival.
Two species are immediately separated and then allowed to mix again through the concept of geneflow.
Founders Effect at work.
