Unit 1

Question 1

What is a structure?

Answer 1

A structure is something put together/constructed
Ex: the shape; the materials made out of

Question 2

What is a function?

Answer 2

A function is how it works; what it does

Question 3

With a different structure will the function be different?

Answer 3

If you change the structure you will change the function

Question 4

How does the structure define the function?

Answer 4

the structure is the “ingredients”, and it will define the function of the object

Question 5

Can the PMC model help determine what is alive and what isn’t?

Answer 5

It can. Scientists can determine if its living by following it.

Question 6

What is the P in PMC?

Answer 6

P is Program it is DNA, and it is what animals and we use

Question 7

What is the M in PMC?

Answer 7

M is metabolism it is all about getting and using energy
EX: food and photosynthesis

Question 8

What is the C in PMC?

Answer 8

Question 11

List in order on the levels of organization that biologists study.

Answer 11

atom -> molecule -> organelles -> cells -> tissues -> organs -> organ system -> organism -> population -> community -> ecosystem -> biome -> biosphere

Question 12

What is the difference between a cell and tissue and how are they the same?

Answer 12

Tissues are formed by cells of similar functions being grouped together. Cells are the smallest structural functional units of organisms while tissues are clusters of specialized cells.
