Evolution

Question 1

Sexual reproduction

Answer 1

A reproductive process that involves two parents that combine their genetic material to produce a new organism which differs from both parents.

Question 2

Asexual reproduction

Answer 2

A reproductive process that involves only one parent and produces offspring that are genetically identical to the parent.

Question 3

Species

Answer 3

A group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce.

Question 4

Adaption

Answer 4

An inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment.

Question 5

Evolution

Answer 5

Change over time; the process by which modern organisms have descended from ancient organisms.

Question 6

Scientific Theory

Answer 6

A well-tested explanation for a wide range of observations or experimental results.

Question 7

Natural Selection

Answer 7

The process by which organisms that are best adapted to their environment are most likely to survive and reproduce.

Question 8

Variation

Answer 8

Any difference between individuals of the same species.

Question 9

Behavioral Adaption

Answer 9

A behavior that helps an organism survive and reproduce in its environment.

Question 10

Structural Adaption

Answer 10

A physical characteristic that allows an organism to survive and reproduce in its environment.

Question 11

Physiological Adaption

Answer 11

A biochemical function that makes an organism better suited to its environment.

Question 12

Hibernation

Answer 12

An animal’s state of greatly reduced activity that occurs during the winter.

Question 13

Migration

Answer 13

The regular, seasonal journey of an animal from one environment to another and back again for the purpose of feeding or reproduction.

Question 14

Selective Breeding

Answer 14

by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together

Question 15

Environmental Pressures

Answer 15

We’ve learned that selective pressures can come in many different forms, such as environmental conditions, threats from predators and diseases, and even human manipulation. Selective pressures drive selection which, in turn, leads to the evolution of a population, or changes in its genetic makeup over time

Question 16

Geotropism

Answer 16

the growth of the parts of plants with respect to the force of gravity. The upward growth of plant shoots is an instance of negative geotropism ; the downward growth of roots is positive geotropism.

Question 17

Phototropism

Answer 17

the orientation of a plant or other organism in response to light, either toward the source of light ( positive phototropism ) or away from it ( negative phototropism ).
