Question #2
A Natural selection does not actually remove any variants in real life.
B Natural selection reduces variation in the trait.
C All of these statements are true.
D Natural selection acts by removing only variants of highest fitness.
Question #3

B was reluctant to publish his theories
C published his theories as soon as he returned from his voyage on the Beagle
D all of these statements are true
Question #6
A Faster gazelles are more likely to escape predators and survive long enough to produce offspring
B The ability to run fast is passed from gazelles to their offspring
C All of these statements are correct
D Predation from lions is a powerful selective pressure
Question #7
A finches with shallow beaks were less likely to survive and reproduce than finches with deep beaks.
B finch beak size had no effect on survival rates.
C more finches with deep beaks died than finches with shallow beaks.
D many more small seeds were available for the finches to eat.
Question #8
A families
B individuals
C species
D groups
Question #9
A strength
B aggressiveness
C age at death
D reproductive success
Question #10
A Population size increases more rapidly than food supplies.
B Species are unchanging types, and individual variation within a species is not important.
C Favorable variations are passed on and accumulate in populations over time.
D There is competition among individuals for resources.
Question #11
A uniformitarianism
B the inheritance of acquired characteristics
C natural selection
D catastrophism
Question #12
A traits are never inherited by offspring.
B the one trait that exists is always advantageous, and change is not necessary.
C there is no competition among individuals.
D no form of a trait is more advantageous than another because all individuals have exactly the same form.
Question #13
A variation is passed from parents to offspring.
B any given environment can support only a certain number of individuals.
C variation affects the ability of individuals to survive and reproduce.
D individuals always compete with each other physically.
Question #14
A bigger organisms surviving at a higher rate than smaller organisms.
B existing variation in organisms.
C the interaction of organisms with their environment.
D heritable variation in organisms.
Question #15
A appreciate the fact that population size is limited by availability of food
B apply his knowledge of domesticated species to undomesticated ones
C claim that favorable variations would tend to be destroyed, unfavorable ones be preserved
D recognize the importance of biological variation within a population

C Is differences in average reproductive success between species
D Was first observed in a species of frog that lays an average of 2,000 eggs
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 Is the number of offspring who survive to an age at which they themselves can reproduce
D Never happens for smaller individuals
