45. Retinoic acid, a metabolite of vitamin A, plays a key role in vertebrate development, differentiation, and organogenesis. Retinoic acid normally binds to the RAR receptor to initiate changes in gene expression.

(A) Muscle cells, but not neurons, contain the gene for the RAR receptor. (B) The RAR receptor gene is expressed in muscle cells but not neurons. (C) Neurons can produce retinoic acid, so they do not need RARs for development. (D) RAR transcripts are hydrolyzed by lysosomes in neurons but not in muscle cells.

46. Vertebrate immune cells, which are phagocytic, include which of the following? I neutrophils； II) macrophages； III) dendritic cells； IV) natural killer cells (A) I and III only (B) II and IV only (C) I and IV only (D) I, II, and III

48. Most of the ATP supplies for a skeletal muscle undergoing prolonged exercise come from________. (A) glucose metabolized by aerobic respiration (B) glycolysis (C) tropomyosin binding to calcium (D) the transfer of a phosphate group from creatine phosphate

49. Coral reefs occur on the southeast coast of the United States, near Florida, but not at similar latitudes on the southwest coast near Los Angeles. Differences in which of the following most likely account for this? (A) air temperatures driven by precipitation (B) day length (C) water temperatures driven by ocean currents (D) marine salinity differences
