adaption

A

is any modification that makes an organism better able to function in a particular environment

24
Q

The theory of evolution

A

suggests how all living things descended from a common ancestor (Charles Darwin)

Q

Systematics

A

is the study of evolutionary relationships between organisms

34
Q

experimental design

the manner in which a scientist conducts an experiment

35
Q

experimental (independent) variable

a good experimental design ensures that the scientist is examining the contribution of a specific factor

36
Q

test group
