Q: Ethers readily dissolve what type of molecules? Read this paragraph and choose the correct option from the provided answers: Ethers are good solvents for other organic compounds because of their low reactivity. They readily dissolve non-polar molecules. Diethyl ether is perhaps the best known ether. It is widely used as a solvent and has been used as an inhalable anesthetic. Choices: - proteins - lipids - polar - non-polar A:
non-polar

Q: Many genetic disorders are caused by mutations in one or a few of? Read this paragraph and choose the correct option from the provided answers: Many genetic disorders are caused by mutations in one or a few genes. Choices: - lesions - organs - blood cells - genes A:
(Answer)
genes

Ques: Q: What device uses an electromagnet to change electrical energy to kinetic energy? Read this paragraph and choose the correct option from the provided answers: An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy. When current flows through the motor, the electromagnet rotates, causing a shaft to rotate as well. The rotating shaft moves other parts of the device. Choices: - public motor - melodic motor - Magnetic motor. - electric motor A:
Ans: electric motor

Q: Baroreceptors in the aortic arch and carotid sinuses monitor what level in the body? Read this paragraph and choose the correct option from the provided answers: 25.9 Regulation of Fluid Volume and Composition The major hormones regulating body fluids are ADH, aldosterone and ANH. Progesterone is similar in structure to aldosterone and can bind to and weakly stimulate aldosterone receptors, providing a similar but diminished response. Blood pressure is a reflection of blood volume and is monitored by baroreceptors in the aortic arch and carotid sinuses. When blood pressure increases, more action potentials are sent to the central nervous system, resulting in greater vasodilation, greater GFR, and more water lost in the urine. ANH is released by the cardiomyocytes when blood pressure increases, causing Na+ and water loss. ADH at high levels causes vasoconstriction in addition to its action on the collecting ducts to recover more water. Diuretics increase urine volume. Mechanisms for controlling Na+ concentration in the blood include the reninangiotensinaldosterone system and ADH. When Na+ is retained, K+ is excreted; when Na+ is lost, K+ is retained. When circulating Ca++ decreases, PTH stimulates the reabsorption of Ca++ and inhibits reabsorption of HPO 24 . pH is regulated through buffers, expiration of CO2, and excretion of acid or base by the kidneys. The breakdown of amino acids produces ammonia. Most ammonia is converted into less-toxic urea in the liver and excreted in the urine. Regulation of drugs is by glomerular filtration, tubular secretion, and tubular reabsorption. Choices: - hunger - air intake - temperature - blood pressure A:
(A).
blood pressure

Ques:Q: What type of species can alternate between medusa and polyp forms? Read this paragraph and choose the correct option from the provided answers: As you can see in Figure below , both body plans have radial symmetry. Some cnidarian species alternate between medusa and polyp forms. Other species exist in just one form or the other. Choices: - mollusks - crocodilian - chordata - cnidarian A:

Ans:cnidarian

Ques: Q: What organ creates bile? Read this paragraph and choose the correct option from the provided answers: The liver is an organ of both digestion and excretion. It produces a fluid called bile , which is secreted into the duodenum. Some bile also goes to the gall bladder , a sac-like organ that stores and concentrates bile and then secretes it into the small intestine. In the duodenum, bile breaks up large globules of lipids into smaller globules that are easier for enzymes to break down. Bile also reduces the acidity of food entering from the highly acidic stomach. This is important because digestive enzymes that work in the duodenum need a neutral environment. The pancreas contributes to the neutral environment by secreting bicarbonate, a basic substance that neutralizes acid. Choices: - kidney - pancreas - heart - liver A:
Ans:
liver
