Answer 28

Heritability

Question 29

is a mechanism by which individuals that have inherited beneficial adaptations produce more offspring on average than do other individuals.

Answer 29

Natural selection

Question 30

is all the individuals of a species that live in an area.

Answer 30

Population

Question 31

is the difference in the physical traits of an individual from those of other individuals in the group to which it belongs:

Answer 31

Variation

Question 32

While having many offspring raises the chance that some will survive, it also results in competition between offspring for resources.

Answer 32

Overproduction

Question 33

Sometimes a certain variation allows an individual to survive better than other individuals it competes against in its environment:

Answer 33

Adaptation

Question 34

Over time, natural selection will result in species with adaptations there are well suited for survival and reproduction in an environment:

Answer 34

Descent with modification
