Q: As blood glucose levels rise what is released from the pancreas? Read this paragraph and choose the correct option from the provided answers: 24.5 Metabolic States of the Body There are three main metabolic states of the body: absorptive (fed), postabsorptive (fasting), and starvation. During any given day, your metabolism switches between absorptive and postabsorptive states. Starvation states happen very rarely in generally well-nourished individuals. When the body is fed, glucose, fats, and proteins are absorbed across the intestinal membrane and enter the bloodstream and lymphatic system to be used immediately for fuel. Any excess is stored for later fasting stages. As blood glucose levels rise, the pancreas releases insulin to stimulate the uptake of glucose by hepatocytes in the liver, muscle cells/fibers, and adipocytes (fat cells), and to promote its conversion to glycogen. As the postabsorptive state begins, glucose levels drop, and there is a corresponding drop in insulin levels. Falling glucose levels trigger the pancreas to release glucagon to turn off glycogen synthesis in the liver and stimulate its breakdown into glucose. The glucose is released into the bloodstream to serve as a fuel source for cells throughout the body. If glycogen stores are depleted during fasting, alternative sources, including fatty acids and proteins, can be metabolized and used as fuel. When the body once again enters the absorptive state after fasting, fats and proteins are digested and used to replenish fat. Choices: - adrenaline - estrogen - hemoglobin - insulin A:
insulin

Q: When does the nucleus divide? Read this paragraph and choose the correct option from the provided answers: The nucleus divides during mitosis, and the cytoplasm divides during cytokinesis. Choices: - meiosis - photosynthesis - epistasis - mitosis A:
(Answer)
mitosis

Ques: Q: Naphthalens is a chemical which is commonly used in what? Read this paragraph and choose the correct option from the provided answers: Delocalization of the electrons makes for a more stable molecule than a similar molecule that does not have delocalized electrons. Benzene is a more stable and less reactive compound than straight-chain hexenes. The sp 2 hybridization of the carbon atoms results in a planar molecule as opposed to the puckered structure of cyclohexane. Benzene rings are common in a great number of natural substances and biomolecules. The figure below shows the structural formulas for vanilla and naphthalene. Naphthalens is a chemical which is commonly used in mothballs. Choices: - shampoo - fertilizers - inhalers - mothballs A:
Ans: mothballs

Q: What can happen spontaneously or as a result of mutagens in the environment? Read this paragraph and choose the correct option from the provided answers: Many mutations are not caused by errors in replication. Mutations can happen spontaneously, and they can be caused by mutagens in the environment. Some chemicals, such as those found in tobacco smoke, can be mutagens. Sometimes mutagens can also cause cancer. Tobacco smoke, for example, is often linked to lung cancer. Choices: - lesions - combustion - traits - mutations A:
(A).
mutations

Ques:Q: A monosaccharide is the simplest carbohydrate and cannot be hydrolyzed to produce a smaller what? Read this paragraph and choose the correct option from the provided answers: A monosaccharide is the simplest carbohydrate and cannot be hydrolyzed to produce a smaller carbohydrate molecule. Disaccharides contain two monosaccharide units, and polysaccharides contain many monosaccharide units. Choices: - amino acid - glucose atom - quark - carbohydrate molecule A:

Ans:carbohydrate molecule
