3
The basic unit of life is
A molecule
DNA
The cell
The atom
4
Metabolism is
The ability of a species to change over time
The ability of living things to process sugar into energy
The basic unit of life
The ability of an organism to respond to its environment
5

Scientists want to study how oil spills affect aquatic plant growth. What's the DV?
Amount of oil spilled
How much the plants grow when exposed to oil.
The plants that aren't exposed to the oil
How long the measurements are taken
7
Homeostasis is
Highly organized into systems
The basic unit of life
The ability to maintain constant internal conditions
A type of data that indicates the quality of something
8
A hypothesis is
An educated statement
A testable guess
An educated guess
A testable statement
9
Single-celled organisms (bacteria, etc) are
Highly organized

Analyze data
11
What happens if your body can't maintain homeostasis?
You develop additional adaptations
