Question #6
A The ability to run fast is passed from gazelles to their offspring
B Predation from lions is a powerful selective pressure
C Faster gazelles are more likely to escape predators and survive long enough to produce offspring
D All of these statements are correct
Question #7
A finch beak size had no effect on survival rates.
B more finches with deep beaks died than finches with shallow beaks.

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 uniformitarianism
B the inheritance of acquired characteristics
C natural selection
D catastrophism
Question #12
A no form of a trait is more advantageous than another because all individuals have exactly the same form.
B the one trait that exists is always advantageous, and change is not necessary.
C traits are never inherited by offspring.
D there is no competition among individuals.
Question #13
A variation is passed from parents to offspring.
B individuals always compete with each other physically.
C any given environment can support only a certain number of individuals.
D variation affects the ability of individuals to survive and reproduce.
Question #14
A existing variation in organisms.
B the interaction of organisms with their environment.
C heritable variation in organisms.

Question #15
A apply his knowledge of domesticated species to undomesticated ones
B recognize the importance of biological variation within a population
C appreciate the fact that population size is limited by availability of food
