Using the image above, which conclusion can be drawn about these organisms?
All four vertebrates move in the same direction
The limbs can be used in water and on land
A lizard is an ancestor of a frog
All four vertebrates share a common ancestor
The hindlimb of the baby whale dissappears as it continues to grow. What information about the development of whales does this tell us?
The embryo shows that the adult whale will have 4 limbs
The whale's embryo development is most likely the same as the frog
Embryo development helps identify a relationship that is not always apparent as adults
Embryo's are important in order to compare what environment the organisms live in
How can genetic variation be introduced into a population of asexual reproducing living things? Remember asexual reproduction is when only one parent is needed to create offspring.
The environment where the organisms live changes so the organism changes
The organisms receive genetic information from both parents.
Mutations occur randomly in the organisms DNA
Why would an organism become resistant to a vaccine? Remember vaccines are medical treatments that provide immunity against diseases.
While being treated with vaccine's some organisms will become stronger and survive to pass on the resistance to offspring.
Organisms gradually become more resistant to vaccines and pass this resistant trait on to their offspring
Organisms that already have a genetic resistance to vaccines will survive and pass on the resistant trait to their offspring
What is natural selection?
The process where organisms that are better adapted to their environment survive and reproduce
The process where organisms change over time
The process where organisms that are not adapted to their environment survive and reproduce
Which scientist coined the term natural selection?
Gregor Mendell
Madame Curry
Charles Darwin
Henrietta Lacks
What is a punnet square used for?
To explain evolution of different organisms
To predict how many offspring an ancestor will have
To describe the relationship between ancestor and off spring
To predict the genotype and phenotype of offspring by crossing two parents of the same species
Who is Gregor Mendel?
A European scientist who discovered the law of inheritance through his work with pea plants
A European scientist who discovered the theory of natural selection through his work with finches on the Galapagos islands
What is the theory of evolution?
The idea that only the strong will survive in a population.
The change in the characteristics of a species over several generations.
Evolution is dependent on the process of natural selection.
false
true
Through his work with finches, Charles Darwin discovered what information?
The genes from a parent are passed down to their offspring and that each offspring receives one set of genes from each aparent
Only the finches who's beaks were best adapted to their environment allowing them to feed themselves in the most efficient way possible were able to survive and reproduce in their population
He did not discover anything
What did Gregor Mendel discover through his work with pea plants?
Only organisms that are best adapted to their environment will survive and reproduce.
The law of inheritance, genes are passed down from parent to offspring and each parent passes down one set of genes to their offspring.
What is a dominant allele?
A trait that is not likely to appear
A trait that is likely to appear
What is a recessive allele?
A trait that is likely to appear
A trait that is not likely to appear
How are dominant alleles notated?
Using lowercase letters to emphasize the idea that they will not appear
Using capital letters to emphasize the idea that they will appear
Using lowercase letters to emphasize the idea that they will appear
Using capital letter to emphasize the idea that they will not appear
Recessive alleles are notated using capital letters
true
false, they are notated using lowercase letters
Dominant traits are likely to appear and will "overpower" recessive traits
true
false
Which of the following is an example of a heterozygous gene?
bb
BB
Bb
Which of the following is an example of a homozygous dominant gene?
Bb
bb
BB
What is a heterozygous gene?
An organism who has the same alleles for a gene
An organism that has two different alleles for a gene.
In which rock layer can the oldest fossils be found?
On the top layer, closest to the Earth's surface
On the second layer from the top
On the third layer from the top
On the bottom layer, farthest from Earth's surface
What does the principle of superposition tell us about fossils? Select all that apply
Lower layers in rock are older because they settled first. New layers formed on top of the older layers.
Higher layers in rock are older because they settled first. New layers formed underneath of the older layers.
Fossils found in the higher rock layers are younger than those found in the bottom rock layers.
Fossils found in the lower rock layers are younger than those found in the top rock layers.
