1. Kinetic Energy
2. Potential Energy

Question 17

Why do life need energy?

Answer 17

To do work and maintain order

Question 18

Change in environment requires the cell or organism to ________.

Answer 18

Adapt

Question 19

Why is adaptation not evolution?

Answer 19

Evolution occurs in a population level not in individual level

Question 20

Physiology

Answer 20

Study of how the human body works and our bodies’ automatic response.
ex. shivering (response to cold)

Question 21

Behavior

Answer 21

Change in activity of an organism in response to stimulus.
ex. choosing to wear a jacket (response to cold).

Question 22

Homeostasis

Answer 22

“Is a self-regulating process by which biological systems maintain stability while adjusting to changing external conditions.

Question 23

What are some homeostatic variables you control?

Answer 23

Anything that goes in and out of our body.
ex. temperature, gas exchange, breathing, etc.

Question 24

Two main ways organism grow?

Answer 24

1. Cell division (increase in cell size and number)
2. Mitosis

Question 25

How is development different form growth?

Answer 25

As the stages the cells go through they multiply and differentiate. ex. panda

Question 26

Two main method of reproduction

Answer 26

- sexual - asexual

Question 27

what cellular processes are involved during reproduction?

Answer 27

Meiosis in humans and mitosis in plants.

Question 28

Does evolution create variation or work on existing variation?

Answer 28

It works on the existing variation.

Question 29

Where does the variation come from?

Answer 29

Mutation (change in DNA sequences)

Question 30

Why is it important to have variation?

Answer 30

To survive and enhance its ability to survive.
