What are the characteristics

1.made up of cells(unicellular,multicellular)
7.DNA 2.Growth(process)and 8.development(cycle 8.die
3."obtain"and "use" energy
4.respond to environment
5.maintain internal energy
6.reproduce
9.evolve

1

Sexual reproduction takes?

Two parents

2

Asexual reproduction takes?

1 parent

3

What is homeostasis?(maintain stable environment category)

Variables are regulated so internal conditions remain stable

4

What is Aneobolism?(build up)

Construct molecules from small units

5

What is Canabolism?(breakdown)

Large molecules are broken down into smaller parts and then used up in respiration

6

What is metabolism?

A set of life‑sustaining chemical transformations within the cells of living organisms. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments.

7

What is science?

An organized way of gathering and analyzing evidence about the natural world

8

What is inferring?

A logical interpretation based on what scientists already know

9

What is a hypothesis?

A scientific explanation for a set of observations that can be tested in ways that support or reject it

"If....,then..."

10

What is the independent variable

The variable that is changed on purpose

Goes on the X axis

11

What is the dependent variable?

The variable that is observed and is changed in response to the independent variable

12

Control group?

The group that is exposed to the same conditions as the experimental group except for 1 independent variable

13

What is a constant?

NOT changed during an experiment

14

What is a stimulus?

A signal to which an organism responds

15

What is a theory?

substantiated explanation of some aspect of the natural world that is acquired through the scientific method, and repeatedly confirmed through observation and experimentation.
