C Individuals can only change when they try to
D Because selection does not produce new variants of traits
Question #2

Question #6
A The ability to run fast is passed from gazelles to their offspring
B All of these statements are correct
C Predation from lions is a powerful selective pressure
D Faster gazelles are more likely to escape predators and survive long enough to produce offspring
Question #7

B reproductive success
C aggressiveness
D strength
Question #10
A There is competition among individuals for resources.
B Favorable variations are passed on and accumulate in populations over time.
C Population size increases more rapidly than food supplies.

Question #11
A the inheritance of acquired characteristics
B natural selection
C catastrophism
D uniformitarianism
Question #12
A no form of a trait is more advantageous than another because all individuals have exactly the same form.

C there is no competition among individuals.
D traits are never inherited by offspring.
Question #13
A individuals always compete with each other physically.
B variation affects the ability of individuals to survive and reproduce.
C any given environment can support only a certain number of individuals.
D variation is passed from parents to offspring.
Question #14
A heritable variation in organisms.
B bigger organisms surviving at a higher rate than smaller organisms.
C the interaction of organisms with their environment.
D existing variation in organisms.
Question #15

B apply his knowledge of domesticated species to undomesticated ones
C recognize the importance of biological variation within a population
D appreciate the fact that population size is limited by availability of food

Question #17
A Was first observed in a species of frog that lays an average of 2,000 eggs
B Is measured as the total number of sex partners over the life span
C Never happens for smaller individuals
