Steps scientists use to test a problem
What is the Scientific Method
All living things get energy from

What is a stimulus?
references aspects that are NON- living
Abiotic Factors

what is a monomer
speeds up the rate of reaction and activation energy... an example in a biological term ...
what is a catalyst? what is an enzyme

What is a Hypothesis?
Maintaining stable internal conditions while external conditions can change
What is homeostasis?

4 Tenents to evolution
What is Variation, Traits are passed on, Overproduction, Many offspring don’t survive because of competition.
where reactants are brought together to react in an enzyme "lock and key"
