What conclusion can we come to by reading the following graph?

• The paramecium grew slowly over the first few days but then its growth sped up

• The paramecium grew quickly over the first few days, but then its growth slowed down

• The paramecium failed to grow during the experiment

Answer explanation

We knew that the paramecium grew quickly over the first few days because the line on the graph shot up like a rocket. Then it started to level out as the growth slowed down.

The independent variable is what you _______ during an experiment.

• change
• do not change 
• measure
• count

Doctors are trying to determine if a certain medication helps to cure migraines. In their experiment, one group is given the new medication while the other group is given a sugar pill (placebo). The group being given the sugar pill is the

• independent variable

• dependent variable

• control group

• experimental group

Answer explanation

The control group DOES NOT receive the independent variable (in this case, the new medication). This group helps to determine whether the experimental medication is actually working.

The largest amount of DNA (genetic information) in a plant cell is contained in

• the nucleus

• all protein molecules

• the vacuole

• the mitochondria
