32. Which of the following statements about hormones and carbohydrate metabolism is NOT correct?
(A) Thyroxine promotes cellular oxidation of glucose; parathyroid hormone inhibits glucose oxidation.
(B) Thyroxine secretion can be regulated by the hypothalamus and the pituitary gland.
(C) Insulin and glucagon act antagonistically to maintain blood glucose homeostasis.
(D) Starvation leads to an increase in glucagon secretion.
(E) Hypothyroidism (low thyroid function) can lead to carbohydrate accumulation in tissues.

33. Which of the following statements about human excretion is correct? (A) The nephron is the structural unit of the kidney, composed of Bowman's capsule, the renal tubule, the glomerulus, and the collecting duct. (B) Antidiuretic hormone (ADH) increases urine volume by promoting sodium excretion in the collecting duct. (C) The filtrate that passes from the glomerulus into Bowman's capsule consists entirely of waste products with no useful substances. (D) The primary function of the renal tubule is reabsorption; it plays no role in the secretion of waste substances into the filtrate. (E) Kidney function is regulated by secretions from the parathyroid glands, the posterior pituitary gland, and the adrenal glands.

34. In the nitrogen cycle, various microbial processes transform nitrogen between its different chemical forms. When decomposers, such as bacteria and fungi, break down the proteins and nucleic acids found in dead organic matter, they release inorganic nitrogen in the form of ammonium (NH₄⁺). What is this specific process called? (A) Nitrogen fixation (B) Ammonification (C) Nitrification (D) Denitrification (E) Assimilation

35. A plant growing in magnesium-deficient soil would most directly exhibit _____. (A) reduced chlorophyll production (B) decreased xylem transport (C) increased transpiration rate (D) enhanced nitrogen fixation (E) increased stomatal density

36. A plant stem is girdled so that phloem transport is disrupted but xylem remains intact. Which of the following processes would continue normally immediately after girdling? (A) Downward movement of sugars from leaves (B) Pressure-flow-driven sucrose movement (C) Distribution of amino acids to roots (D) Translocation of photosynthates to fruits (E) Long-distance transport of water to leaves

37. In a temperate forest ecosystem, a mutation spreads through fungal populations that prevents the formation of multicellular hyphae, restricting fungi to unicellular growth forms. Although metabolic pathways for enzyme production remain intact, the organisms cannot form extensive filamentous networks in soil or woody substrates. Which ecosystem-level process would most likely experience the greatest decline as a direct consequence? (A) Net primary productivity by autotrophs (B) Atmospheric nitrogen fixation rates (C) Oxygenic photosynthesis in the canopy (D) Breakdown of lignin-rich plant biomass (E) Carbon fixation by soil microbes

38. In chloroplasts, inhibition of photosystem II would most directly reduce the production of _____. (A) NADPH and the proton gradient across the thylakoid membrane (B) ATP generated by substrate-level phosphorylation (C) glucose during the Calvin cycle (D) RuBP regeneration (E) oxygen consumption by mitochondria

39. Which characteristic represents a synapomorphy uniting ecdysozoans (e.g., arthropods and nematodes) and most clearly distinguishes them from other bilaterian invertebrates? (A) Presence of a fluid-filled body cavity (B) Expression of radial body symmetry (C) Periodic molting of an external cuticle (D) Development of repeated body segments (E) Possession of an open circulatory system

40. Which population characteristic is most directly regulated by density-dependent factors? (A) Carrying capacity (K) (B) Birth rate during a catastrophic event (C) Intrinsic rate of increase (r) (D) Dispersal ability (E) Age at sexual maturity

41. According to the pressure-flow model of phloem transport, long-distance movement of sucrose depends primarily on _____. (A) active transport of water into sieve-tube elements at the source (B) capillary forces within sieve plates (C) a pressure difference established between source and sink tissues (D) diffusion of sucrose through plasmodesmata over long distances (E) bulk flow driven by transpiration in xylem vessels

42. A population of 10,000 diploid organisms shows genotype frequencies that initially conform to Hardy–Weinberg expectations. Over the next generation, which of the following scenarios would be expected to produce the largest deviation from Hardy–Weinberg genotype proportions in a single generation? (A) A 1% migration rate from a genetically similar neighboring population (B) Mild inbreeding with an inbreeding coefficient F = 0.05 (C) Occasional mutation at a rate of 10⁻⁶ per allele per generation (D) A temporary reduction of population size to 5,000 individuals (E) Heterozygote disadvantage reducing heterozygote fitness by 50%
