1) both the neural and endocrine systems play a role in coordinating body activities.
2) most chromalveolateshave the alternation of generations life cycle, but some species
of fungus have a diplontic life cycle.
3) chemiosmotic atp synthesis occurs in the cytosol of the cell.
4) small, variable regions of dna that may change an individual's susceptibility to
disease are called proteomes.

14) the fact that a nucleic acid is a very complicated molecule suggests that
a. the rna-first hypothesis is impossible.
b. rna could not have arisen on its own by chance, but required enzymes to guide the
synthesis of nucleotides and then nucleic acids.
c. sophisticated enzymes were not present or available to synthesize it.
d. no natural system could ever generate it.
e. the protein-first hypothesis is therefore the only plausible hypothesis.

a. repeatedly encourage the child to perform a behavior and then reward the good
behavior so the child associates the behavior with the reward.
b. repeatedly encouragethe child to perform a behavior and then wait several days
before rewarding the good behavior so the child associates the behavior with the
reward.

the good behavior so the child associates the behavior with the reward.
d never encourage a specific behavior from a child but randomly give them rewards.
