Evolution; Unity and Diversity 3

Question 1

Advantageous Trait

Answer 1

make an organism more likely to survive and reproduce in its environment.

Question 2

Coevolution

Answer 2

the reciprocal evolutionary change in a set of interacting populations over time resulting from the interactions between those populations.

Question 3

Convergent Evolution

Answer 3

occurs when organisms that aren’t closely related evolve similar features or behaviours, often as solutions to the same problems.

Question 4

Distribution

Answer 4

the action of sharing something out among a number of recipients.

Question 5

Divergence

Answer 5

The evolution of different forms or structures in related species as they adapt to different environments.

Question 6

Ecosystem

Answer 6

a biological community of interacting organisms and their physical environment.

Question 7

Fitness

Answer 7

Biological fitness is defined as an organism’s ability to pass its genetic material to its offspring.

Question 8

Gene

Answer 8

(in informal use) a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

Question 13

Gene Pool

Answer 13

the combination of all the genes (including alleles) present in a reproducing population or species.

Question 14

Phenotypic Variation

Answer 14

the variability in phenotypes that exists in a population

Question 15

Population

Answer 15

a group of organisms living in the same geographical area at the same time

Question 16

Survival Rate

Answer 16

Question 17

Variation

Answer 17

a change or difference in condition, amount, or level, typically with certain limits.
