Answer the following question given this paragraph: Nutrients the body needs in relatively small amounts are called micronutrients . They include vitamins and minerals. Vitamins are organic compounds that are needed by the body to function properly. Several vitamins are described in Table below . Vitamins play many roles in good health, ranging from maintaining good vision to helping blood clot. Vitamin B12 is produced by bacteria in the large intestine. Vitamin D is synthesized by the skin when it is exposed to UV light. Most other vitamins must be obtained from foods like those listed in Table below . Q: What is the term for nutrients the body needs in relatively small amounts, including vitamins and minerals? Choices: - minor nutrients - insignificant nutrients - trace nutrients - micronutrients A:
(Answer)
micronutrients

Answer the following question given this paragraph: Vacuoles are membrane-bound organelles that can have secretory, excretory, and storage functions. Vacuoles are usually much larger than vesicles. Many organisms will use vacuoles as storage areas and some plant cells have very large vacuoles. The large central vacuole of the plant cell is used for osmotic control (storage of water) and nutrient storage. Contractile vacuoles are found in certain protists. These vacuoles take water from the cytoplasm and excrete it from the cell to avoid bursting due to osmotic pressure. Q: These vacuoles take water from the cytoplasm and excrete it from the cell to avoid bursting due to what? Choices: - apoptotic pressure - static pressure - impervious pressure - osmotic pressure A:
(Answer)
osmotic pressure

Answer the following question given this paragraph: When you pour a glass of water, or fill a car with gasoline, you observe that water and gasoline flow freely. But when you pour syrup on pancakes or add oil to a car engine, you note that syrup and motor oil do not flow as readily. The viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 10.15, have higher viscosities. We can measure viscosity by measuring the rate at which a metal ball falls through a liquid (the ball falls more slowly through a more viscous liquid) or by measuring the rate at which a liquid flows through a narrow tube (more viscous liquids flow more slowly). Q: The viscosity of a liquid is a measure of what? Choices: - resistance to change form - ability to absorb flow - adaptability to surroundings - resistance to flow A:
(Answer)
resistance to flow
