Connor decides to celebrate his 21st birthday by drinking a few beers at a local sports bar. After a while, Connor notices that he is making many more trips to the men's room than the week before when he drank similar amounts of carbonated water. Why is that?
A. Alcohol inhibits reabsorption of sugars, amino acids and other small metabolites, which decreases reabsorption of water.
B. Alcohol stimulates secretion of ions into the nephron and water follows by osmosis.
C. Alcohol inhibits the secretion of ADH by the posterior pituitary gland, thereby decreasing water reabsorption.
D. Alcohol stimulates filtration of the blood plasma by the glomeruli.
E. Alcohol stimulates the insertion of aquaporins into the plasma membranes of cells that line the collecting ducts, thereby decreasing water reabsorption.

Of these 4 genotypic classes of offspring, which arose from a parental gamete produced by the F1 females? (Select all that apply.)
In Drosophila, singed bristles (sn) and cut wings (ct) are both caused by recessive, X-linked alleles. The wild type alleles (sn+ and ct+) are responsible for straight bristles and intact wings, respectively. A female homozygous for sn and ct+ is crossed to a sn+ct male. The F1 flies are interbred. The F2 males are distributed as follows:
A) sn+ ct+
B) sn ct
C) sn+ ct
D) sn ct+

B) DNA replication in most cells stops when the double helix comes in contact with particular enzymes. C) most cells stop dividing when they bump up against other cells or collections of cells. D) DNA replication in most cells doesn't begin until the double helix comes in contact with particular enzymes. E) most cells stop dividing when they have reached 50 cell divisions.
