Is needed to justify the sample size
Serves as the control for the experiment
Is needed to formulate a hypothesis
Serves as the conclusion for the experiment

8
The unique banding pattern created by gel electrophoresis is called a
DNA fingerprint
restriction enzyme
transgenic organism
recombinant plasmid
9
The building blocks of starch are
lipds
glucose molecules
amino acids
proteins
10
The finches had different beaks so they could....
to make different sounds
eat different food
no reason
11
The inside of the model cell turned blue black because
iodine (starch indicator) diffused into the cell
glucose diffused into the cell
starch diffused out of the cell
Benedict's solution diffused into the cell
12
diffusion...
makes proteins
requires no energy
requires energy
is the same as active transport
13
What color is Iodine in the presence of starch?
green
Blue/Black
Yellow

14
Independent variable? Exercise lowers blood pressure
Blood Pressure
Amount of exercise
15
What is an advantage of a change in pulse rate after exercising?
the blood is carrying ATP
The blood is removing oxygen from muscle cells
none of these
Increased blood flow carries excess wastes from muscle cells
