The fact that the eye structures of vertebrates and insects are analogous
The fact that the genes encoding the eye structures of vertebrates and insects are analogous
The fact that the eye developmental genes of vertebrates and insects are homologous
What does it mean that the eye structures and specific genes for those structures are analogous but the genes that control eye development are homologous?
Select all that apply
It means vertebrates and insects had a common ancestor that possessed genes that coded for a primitive eye
It means every species that descended from the common ancestor developed additional genes that made changed the structure of their eye
It means that vertebrates and insects are not related to each other but developed eyes in a similar pattern
Which of these statements does NOT help explain why the development of gene sequencing technology provided a turning point in evidence gathering related to this claim?
Select all that apply
Before gene sequencing, the only evidence was the anatomical appearance of the eyes of vertebrates and insects
Because the eye structures are so different in appearance, it was easy to conclude these groups had no evolutionary relationship with each other
Gene sequencing shows that there are enough genetic similarities in the genes of eye development to suggest a very early common ancestor
Gene sequencing shows that, since the genes encoding eye structures are analogous, that vertebrates and insects share no common ancestors

The pair of population graphs below display the results of two different five-year hunting cycles, one on light trees and one on dark trees. The population of light-colored moths is shown by the light gray dots, and the population of dark moths is shown by the dark gray dots. How do these results demonstrate natural selection?
The moth populations shown here demonstrate random fluctuations over time that are not explained by tree color.
On light trees, individual moths tried to become lighter in color to match the tree background. On dark trees, individual moths tried to become darker in color.
The moths that were the same color as their background were more likely to survive and reproduce. Over time, the populations of these well-adapted moths increased.
Small particles of tree bark became embedded in the moth’s wings, causing the moths to become darker on the dark trees and lighter on the light trees. These acquired traits were then passed down to the next generation of moths, causing the populations to change color over time.
Suppose a certain species of insect lives in the lush green canopy of the rain forest. Some of the insects are bright green in color, and some are bright yellow. Assume there is a natural predator of the insect in the area. What do you expect to happen to the populations of the green and the yellow insects over time?
The green insect population will increase and the yellow insect population will decrease.
The green insect population will decrease and the yellow insect population will increase.
Both insect populations will remain constant over time.
Both insect populations will increase over time.
Which of the following statements best describes what will most likely occur to the moth populations in the image above?
The light moths will be captured by predators more easily than the dark moths, and the population of dark moths will rise.
The light moths will be captured by predators more easily than the dark moths, and the population of light moths will rise.
The dark moths will be captured by predators more easily than the light moths, and the dark moths will probably go extinct.
The light moths will change their wing color to match that of the dark moths.
What is the most likely explanation of the data shown below?
There has been a drought in the area that is affecting all life forms.
The population of natural predators of the moths has gotten smaller.
The moths are living in an environment with light trees.
The moths are living in an environment with dark trees.
What is an example of artificial selection?
Letting dogs choose their own mate
Letting plants pollinate on their own
Crossing a labrador and a poodle to create a labradoodle
Which statement is true comparing natural selection and artificial selection?

In natural selection, traits benefit the species and in artificial selection, the traits benefit humans
In natural and artificial selection, the process takes hundreds of years to occur
In natural and artificial selection, nature determines what traits will be passed down to offspring.

A particular bird species lays an average of 4 eggs per nesting season. If more than four eggs are produced, the parents may not be able to feed the hatchlings. If less than 4 eggs are produced, there is an increased risk that predators will take all the young that have been produced. (a)
A lizard population lives in a very rocky area consisting of black rocks and white rocks. Black lizards can hide from predators by living on black rocks, and white lizards can hide from predators by living on white rocks. The intermediate grey colored lizard is found in fewer numbers because of its inability to hide from predators in this environment. (a)
