natural selection and evolutio

Question 1

structural adaptation

Answer 1

physical feature that contributes to survival

Question 2

mimicry

Answer 2

resemblance of one species to another

Question 3

physiological adaptations

Answer 3

changes in organisms METABOLIC and CHEMICAL processes

Question 4

behavioral adaptations

Answer 4

inherited behaviors that help survival

Question 5

microevolution

Answer 5

small change within population

Question 6

macroevolution

Answer 6

large change in population

Question 7

fitness

Answer 7

organisms ability to reproduce fertile offspring

Question 8

disruptive selection

Answer 8

both/either extremes have most optimal adaptations for environment, average/middle drops or goes extinct

Question 9

directional selection

Answer 9

one extreme has best adaptation for environment, other side drops

Question 10

stabilizing selection

Answer 10

both/either extremes adaptations aren’t optimal for environment, middle rises/survives

Question 11

gene pool

Answer 11

all the alleles of a population’s genes, used for giving population diversity

Question 12

gene drift- bottleneck effect

Answer 12

eliminates genes from a population (naturally)

Question 13

gene drift- founder effect

Answer 13

few members leave and start new population

Question 14

homologous structures

Answer 14

have similar body structures, all inherited from CA, but do different functions

Question 15

analogous structures

Answer 15

body parts have same functions, different structure (different ancestor)

Question 16

vestigial structures

Answer 16

body structure that no longer functions

Question 17

non-random mating

Answer 17

individuals choose mates based on physical traits (sexual attraction)
