Question 1

The mechanism of natural selection works, primarily, to change which of the following?

A The genotypes of individual organisms and their expression

B The rate of mutations resulting from external factors

C The distribution of traits in a population over time

D The likelihood that traits of organisms are passed on

Question 2

A Soil lacking nutrients

B Abundant herbivores

C Little or no rainfall

D Low insect population

Question 3

A  there is variation in genes in a population

B genetic traits are heritable across generations.

C genetic information is stored on chromosomes.

D genes result in traits that provide advantages.

Question 4

A Within the population, the amount of cotton fiber produced per plant would shift to be greater.

B The geographic range of insects that feed on cotton would become more restricted.

C New varieties of cotton that produce enzymes similar to the pesticide would evolve.

Question 5

A The frequency in the population of individual plants that produce high levels of ammonia in their roots increases with soil acidity.

B As the acidity of the soil increases, the number of individual plants able to survive and reproduce decreases.

C When the plants are grown in soil with a neutral pH, the levels of ammonia in the roots of the plants remains stable over generations.
