Answer the following question given this paragraph: Global air currents cause global winds. The figure below shows the direction that these winds blow ( Figure below ). Global winds are the prevailing, or usual, winds at a given latitude. The winds move air masses, which causes weather. Q: Winds moving air masses causes what? Choices: - earthquake - tremors - tsunami - weather A:
weather

Ques: Answer the following question given this paragraph: Endocrinologist An endocrinologist is a medical doctor who specializes in treating disorders of the endocrine glands, hormone systems, and glucose and lipid metabolic pathways. An endocrine surgeon specializes in the surgical treatment of endocrine diseases and glands. Some of the diseases that are managed by endocrinologists: disorders of the pancreas (diabetes mellitus), disorders of the pituitary (gigantism, acromegaly, and pituitary dwarfism), disorders of the thyroid gland (goiter and Graves' disease), and disorders of the adrenal glands (Cushing's disease and Addison's disease). Endocrinologists are required to assess patients and diagnose endocrine disorders through extensive use of laboratory tests. Many endocrine diseases are diagnosed using tests that stimulate or suppress endocrine organ functioning. Blood samples are then drawn to determine the effect of stimulating or suppressing an endocrine organ on the production of hormones. For example, to diagnose diabetes mellitus, patients are required to fast for 12 to 24 hours. They are then given a sugary drink, which stimulates the pancreas to produce insulin to decrease blood glucose levels. A blood sample is taken one to two hours after the sugar drink is consumed. If the pancreas is functioning properly, the blood glucose level will be within a normal range. Another example is the A1C test, which can be performed during blood screening. The A1C test measures average blood glucose levels over the past two to three months by examining how well the blood glucose is being managed over a long time. Once a disease has been diagnosed, endocrinologists can prescribe lifestyle changes and/or medications to treat the disease. Some cases of diabetes mellitus can be managed by exercise, weight loss, and a healthy diet; in other cases, medications may be required to enhance insulin release. If the disease cannot be controlled by these means, the endocrinologist may prescribe insulin injections. In addition to clinical practice, endocrinologists may also be... Q: What doctors specialize in diseases stemming from glandular issues? Choices: - anthropologists - dermatologists - oncologists - endocrinologists A:
Ans: endocrinologists

Answer the following question given this paragraph: Mammals breathe with the help of a diaphragm. This is the large muscle that extends across the bottom of the chest below the lungs. When the diaphragm contracts, it increases the volume of the chest. This decreases pressure on the lungs and allows air to flow in. When the diaphragm relaxes, it decreases the volume of the chest. This increases pressure on the lungs and forces air out. Q: What muscle in the chest helps inflate and deflate the lungs? Choices: - pectoral - cartilage - heart - diaphragm A:
(A).
diaphragm
Ques:Answer the following question given this paragraph: The reaction of an alkyl halide with an inorganic hydroxide base at elevated temperature produces an alcohol. The molecular reaction to produce methanol from iodomethane and sodium hydroxide is shown below. Q: The reaction of an alkyl halide with an inorganic hydroxide base at elevated temperature produces what? Choices: - blood - methane - yeast - an alcohol A:

Ans:an alcohol
Question: Answer the following question given this paragraph: Because the health of cells depends on maintaining the proper levels of cations in intracellular fluids, any change that affects the normal flux of metal ions across cell membranes could well cause an organism to die. Molecules that facilitate the transport of metal ions across membranes are generally called ionophores (ionplus phore from the Greek phorein, meaning "to carry"). Many ionophores are potent antibiotics that can kill or inhibit the growth of bacteria. An example isvalinomycin, a cyclic molecule with a central cavity lined with oxygen atoms (part (a) in Figure 21.14 "Valinomycin Is an Antibiotic That Functions Like an Ionophore") that is similar to the cavity of a crown ether (part (a) in Figure 13.7 "Crown Ethers and Cryptands"). Like a crown ether, valinomycin is highly selective: its affinity for K+ is about 1000 times greater than that for Na+. By increasing the flux of K+ ions into cells, valinomycin disrupts the normal K+ gradient across a cell membrane, thereby killing the cell (part (b) in Figure 21.14 "Valinomycin Is an Antibiotic That Functions Like an Ionophore"). Figure 21.14 Valinomycin Is an Antibiotic That Functions Like an Ionophore. Q: Why is it necessary to maintain proper levels of cations in intercellular fluids? Choices: - cell division - reverse homeostasis - for digestion - keep cells healthy A:
Answer:
keep cells healthy
