Q: Why does water have a high surface tension? Read this paragraph and choose the correct option from the provided answers: Choices: - high freezing point - helium bonding - oxygenation - hydrogen bonding A:
hydrogen bonding

Q: What exposure risk comes with aerobic respiration? Read this paragraph and choose the correct option from the provided answers: In summary, aerobic and anaerobic respiration each have advantages under specific conditions. Aerobic respiration produces far more ATP, but risks exposure to oxygen toxicity. Anaerobic respiration is less energy-efficient, but allows survival in habitats which lack oxygen. Within the human body, both are important to muscle function. Muscle cells specialized for aerobic respiration provide endurance, and those specialized for lactic acid fermentation support short but intense energy expenditures. Both ways of making ATP play critical roles in life on earth. Choices: - helium toxicity - carbon toxicity - nitrogen toxicity - oxygen toxicity A:
oxygen toxicity

Q: Catabolic and anabolic hormones in the body help regulate these? Read this paragraph and choose the correct option from the provided answers: Hormonal Regulation of Metabolism Catabolic and anabolic hormones in the body help regulate metabolic processes. Catabolic hormones stimulate the breakdown of molecules and the production of energy. These include cortisol, glucagon, adrenaline/epinephrine, and cytokines. All of these hormones are mobilized at specific times to meet the needs of the body. Anabolic hormones are required for the synthesis of molecules and include growth hormone, insulin-like growth factor, insulin, testosterone, and estrogen. Table 24.1 summarizes the function of each of the catabolic hormones and Table 24.2 summarizes the functions of the anabolic hormones. Choices: - brain signals - hormone levels - nutrient levels - metabolic processes A:
metabolic processes
