Regents Evolution Unit Test Review

An example of a population in which evolution could take place in a relatively short period of time could be

• pathogenic bacteria exposed to antibiotics

• oak trees in a stable ecosystem

• elephants living in a wildlife preserve

• algae grown under constant conditions

In the photograph below, two fish are displaying a behavior commonly observed among pairs of rabbitfish. While one has its head down feeding on coral, the other remains upright, alert for predators.

This behavior continues to be present in the rabbitfish population because

• this behavior was learned by observing other fish species

• both fish could not fit into the small spaces in the coral

• this behavior increases their chance of survival

• the fish species needed to become alert to survive

A genetic change that occurs in a body cell of a mouse will not contribute to the evolution of the species because

• body cell mutations will cause the cell to die before it reproduces

• the evolution of a species can result from changes in reproductive cells, not body cells

• random changes are repaired by enzymes before they are passed on to offspring

• the evolution of a species is caused by natural selection, not genetic variation

Scientists who have examined the fossil record have noted that some species have changed very little over long periods of geologic time. The lack of change in such organisms is most likely because

• all members of their population were genetically identical, and they lived in a rapidly changing environment

• there was a large amount of variation in their population, and the environment changed frequently

• they could move between different environments when food supplies became scarce

• the environment that they lived in remained the same, and they were well-adapted to it.

Base your answer to this question on the information below and on your knowledge of biology.

Fossil Footprints

Scientists examined a trail of fossil footprints left by early humans in soft, volcanic ash in Eastern Africa. A drawing of the trail of footprints is shown below. Each footprint is represented as a series of lines indicating the depth that different parts of the foot sank into the volcanic ash.

• The individuals were running from a predator.

• The volcano was about to erupt again.

• One individual was much taller than the other.

• One individual had larger feet than the other.

A biologist conducting a long-term field study noticed there were two types of mice in a valley. One type of mouse had webbed toes, and one type of mouse lacked webbed toes. A dam was built in the valley turning the land to wetland. As the years passed, all mice living in the valley were found to have webbed toes. No mice were found with non-webbed toes.

Which statement best explains the observed change in the mouse population?

• Webbed toes in mice are controlled by the environment.

• The mice grew webbing to move more efficiently in the new environment.

• Webbed-toed mice survived better and reproduced more than mice without webbed toes.

• The increased water levels in the valley increased the mutation rate in the mouse population.

Which of the following is NOT an example of natural selection? 

• People selectively breeding hamsters.
• Insect populations developing resistance to certain pesticides.
• Bacteria becoming resistant to antibiotics.
• Male birds of certain species developing colorful feathers to attract female mates.
