Question 1

What is biology?

Answer 1

Biology is the scientific study of life

Question 2

Order

Answer 2

Organisms are built with orderly structure

Question 3

Reproduction

Answer 3

Organisms reproduce like kind

Question 4

Growth and development

Answer 4

Organisms undergo consistent growth and development which is controlled by inherited DNA

Question 5

Energy processing

Answer 5

Use chemical energy to power their cellular activities and exchange energy w the environment

Question 6

Response to environment

Answer 6

Response to environmental stimuli (Venus fly trap)

Question 7

Regulation

Answer 7

All organisms control internal environment within limits that sustain life

Question 8

Evolutionary adaptation

Answer 8

All populations of living things have the ability to change over time due to the passing of successful traits from parent to offspring

Evolution=change over time
Successful traits=adaptations
