How can analysis of mammalian genomes be used to detect and treat human disease? Check all that apply.
_____ The genomes of the mammalian relatives of humans are the best targets for discovering new treatments for human diseases.
_____ Comparing the genomes of parasite and host is likely to reveal good drug targets to eliminate the parasite without harming the host.
_____ A comparison of mouse and human genomes would help reveal functions for previously unidentified human genes.
_____ A comparison of human and mouse genomes would help observe DNA sequences that evolved prior to the evolution of mammals.

When blood osmolarity increases:
A) the kidneys excrete more water from the body through diuresis in an attempt to normalize the blood's osmolarity. B) osmoreceptors located in the hypothalamus stimulate the release of vasopressin, which causes the body to retain water. C) the pituitary gland releases antidiuretic hormone (ADH), which stimulates the kidneys to resorb water and decrease the blood's osmolarity. D) volume-sensitive receptors in the atria stretch, causing the release of natriuretic proteins that normalize the blood's osmolarity.
A persistent infection is one in which
A) the virus remains in equilibrium with the host without causing a disease. B) viral replication is unusually slow. C) the disease process occurs gradually over a long period. D) host cells are gradually lysed. E) host cells are transformed.
