B Individuals can only change when they try to
C Because large changes are better than small increments of change when breeding by blending
D Because selection does not produce new variants of traits
Question #2
A All of these statements are true.
B Natural selection reduces variation in the trait.
C Natural selection acts by removing only variants of highest fitness.
D Natural selection does not actually remove any variants in real life.

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

Question #8
A species
B individuals
C families
D groups
Question #9
A age at death
B aggressiveness
C reproductive success
D strength
Question #10
A Species are unchanging types, and individual variation within a species is not important.
B There is competition among individuals for resources.
C Favorable variations are passed on and accumulate in populations over time.
D Population size increases more rapidly than food supplies.
Question #11
A the inheritance of acquired characteristics
B natural selection
C uniformitarianism
D catastrophism
Question #12
A the one trait that exists is always advantageous, and change is not necessary.
B no form of a trait is more advantageous than another because all individuals have exactly the same form.
C traits are never inherited by offspring.
D there is no competition among individuals.
Question #13
A variation affects the ability of individuals to survive and reproduce.
B individuals always compete with each other physically.
C any given environment can support only a certain number of individuals.
D variation is passed from parents to offspring.
Question #14
A the interaction of organisms with their environment.
B bigger organisms surviving at a higher rate than smaller organisms.
C existing variation in organisms.
D heritable variation in organisms.
Question #15
A recognize the importance of biological variation within a population
B claim that favorable variations would tend to be destroyed, unfavorable ones be preserved
C apply his knowledge of domesticated species to undomesticated ones
D appreciate the fact that population size is limited by availability of food
Question #16
A Is differences in average reproductive success between species
B Is differences in reproductive success between individuals of the same group
C Was first observed in a species of frog that lays an average of 2,000 eggs
D Is observed when an individual’s parents have different numbers of offspring
Question #17
A Is the number of offspring who survive to an age at which they themselves can reproduce
B Is measured as the total number of sex partners over the life span
C Never happens for smaller individuals
D Was first observed in a species of frog that lays an average of 2,000 eggs
