Question 1

Coevolution

Answer 1

Close ecological relationship that Cy as agents of natural selection for each other ( insects and plants)

Question 2

Adaptive radiation

Answer 2

Process by which a single species or small group of species evolves over a relatively short time into several different forms

Question 3

Behavioral isolation

Answer 3

Helps members of the same species identify each other as proper mates

Question 4

Reproductive isolation

Answer 4

May live in the same place but imdidvidual properties prevent interbreeding

Question 5

Temporal isolation

Answer 5

Keeps individuals of different species from interbreeding even if they live in the same environment

Question 6

Geographic isolation

Answer 6

Deprecation of two populations of the same species or breeding group by a physical barrier such as mountains or oceans

Question 7

Backroumd extinction

Answer 7

Special become extinct because of natural selection

Question 8

Mass extinction

Answer 8

Many species become extinct I’m a short period of time

Question 9

Genetic drift

Answer 9

Random changes in allele frequency Affects small populations

Question 10

Mutations

Answer 10

Caused by; environmental factors
Lethal- does not survive
Beneficial- become part of the gene pool

Gene flow

Answer 12

Movement of individuals into and put of a population
