Answer the following question given this paragraph: Most tunicates live a sessile existence in shallow ocean waters and are suspension feeders. The primary foods of tunicates are plankton and detritus. Seawater enters the tunicate's body through its incurrent siphon. Suspended material is filtered out of this water by a mucus net (pharyngeal slits) and is passed into the intestine through the action of cilia. The anus empties into the excurrent siphon, which expels wastes and water. Lancelets possess a notochord, dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail in the adult stage (Figure 15.35). The notochord extends into the head, which gives the subphylum its name (Cephalochordata). Extinct fossils of this subphylum date to the middle of the Cambrian period (540488 mya). The living forms, the lancelets, are named for their blade-like shape. Lancelets are only a few centimeters long and are usually found buried in sand at the bottom of warm temperate and tropical seas. Like tunicates, they are suspension feeders. Q: Most tunicates live a sessile existence in shallow ocean waters and are suspension feeders. the primary foods of tunicates are plankton and this? Choices: - bacteria - crustaceans - debris - detritus A:
(Answer)
detritus

(Q).
Answer the following question given this paragraph: Sebaceous glands produce an oily substance called sebum . Sebum is secreted into hair follicles and makes its way to the skin surface. It waterproofs the hair and skin and helps prevent them from drying out. Sebum also has antibacterial properties, so it inhibits the growth of microorganisms on the skin. Q: Sebaceous glands produce an oily substance called what? Choices: - ear wax - pus - synovial fluid - sebum A:
(A).
sebum
Ques:Answer the following question given this paragraph: Diabetes mellitus is a disorder of glucose metabolism in which insulin production by the pancreas is impaired. Since insulin helps glucose enter the cells, a decrease of this hormone means that glucose cannot be used in its normal fashion. When this happens, the body begins to break down fats, producing a decrease in blood pH. Chemical systems in the body can balance this pH shift for a while, but excessive acid production can create serious problems if not corrected by administering insulin to restore normal glucose use. Q: What is a disorder of glucose metabolism in which insulin production by the pancreas is impaired? Choices: - cluster mellitus - populations mellitus - sugar mellitus - diabetes mellitus A:

Ans:diabetes mellitus
Question: Answer the following question given this paragraph: 15.6 Entropy and the Second Law of Thermodynamics: Disorder and the Unavailability of Energy Entropy is the loss of energy available to do work. Another form of the second law of thermodynamics states that the total entropy of a system either increases or remains constant; it never decreases. Entropy is zero in a reversible process; it increases in an irreversible process. The ultimate fate of the universe is likely to be thermodynamic equilibrium, where the universal temperature is constant and no energy is available to do work. Entropy is also associated with the tendency toward disorder in a closed system. Q: What is the loss of energy available to do work called? Choices: - negentropy - force - power - entropy A:
Answer:
entropy
