the action or process of adapting or being adapted.

Question 2

Behavior

Answer 2

Question 3

Competition

Answer 3

to the rivalry between or among living things for territory, resources, goods, mates

Question 4

Fitness

Answer 4

Fitness is a quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype

Question 5

Gene Pool

Answer 5

A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species

Question 6

Genetic Variation

Answer 6

Genetic variation is the presence of differences in sequences of genes between individual organisms of a species.

Question 7

Geographic Isolation

Question 9

Natural Selection

Answer 9

Natural selection, process in which an organism adapts to its environment through selectively reproducing changes in its genotype.

Question 10

Phenotypic Expression

Answer 10

the observable characteristics in an organism that results from the expression of genes.

Answer 14

natural selection arising through preference by one sex for certain characteristics in individuals of the other sex.

Question 15

Speciation

Answer 15

occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
