Why bother to outline? Outlining helps one:

I. identify the main ideas.

Il. identify systems and their components.

III. improve the ability to retrieve information from the

long-term memory.

IV. increase the amount of information that enters the

short-term memory

I, II, III, IV

You wake up the morning after a party and think you see a 3 ft x 4 ft Amoeba. Luckily, you practiced biology before the party and know that, because Amoeba are single-celled organisms, there could not be an Amoeba this big because it would have too:

much cell volume relative to its surface area for gas exchange to occur adequately.

A t-test of two means returns 0.81. What is the probability that any observed difference between the two means is due to chance rather than a real difference?
