The answer is Walter Hess
Hess manipulated the diancephalon of the brain of cats by inserting metal rods in the hypothalamus regions of the brain, where the diencephalon is located, and passing electrical current through the rods to the brain region. He noticed that the cats, among other complex behavioral changes, would curl up and sleep.
Its the epidermis because it is subdivided into two layers.
Answer: The Organism is most likely to be a starfish
I will try my best to answer your question
Shearing forces-rationale: friction, impaired circulation, localized pressure, and shearing forces are all risk factors of pressure ulcer development; trapeze use reduces shearing forces. shearing forces (opposing forces that cause layers of skin to move over each other, stretching and tearing capillaries and, eventually, resulting in necrosis) can occur as clients slide down in bed or are pulled up in bed. subcutaneous skin layers adhere to the sheets while deeper layers, muscle, and bone slide in the direction of movement. to reduce shearing forces, the nurse should instruct the client to use an overbed trapeze, place a draw sheet under the client to move him up in bed, and keep the head of the bed no higher than 30 degrees.client needs category: physiological integrityclient needs subcategory: basic care and comfortcognitive level: applicationreference: taylor, c., et al. fundamentals of nursing: the art and science of nursing care, 6th ed. philadelphia: lippincott williams & wilkins, 2008, p. 1196.
Answer:
c. a high percentage of very long chain saturated fatty acids
Explanation:
Saturated fatty acids do not have double bonds (they are saturated with hydrogens), so their tails are relatively straight. Unsaturated fatty acids, on the other hand, contain one or more double bonds, which often produces an elbow or bend. (You can see an example of an unsaturated bent tail in the phospholipid structure diagram that appears at the beginning of this article.) Saturated and unsaturated phospholipid fatty acid tails behave differently when the temperature drops:
- At colder temperatures, the straight tails of saturated fatty acids can be tightly bound, producing a dense and quite rigid membrane.
- Phospholipids with unsaturated fatty acid tails cannot bind so closely due to the bent structure of their tails. For this reason, an unsaturated phospholipid membrane remains fluid at lower temperatures than a saturated phospholipid membrane.
Most cell membranes contain a mixture of phospholipids, some with two saturated (straight) tails and others with a saturated tail and an unsaturated (folded) tail. <u>Many organisms — fish, for example — can adapt physiologically to cold environments by changing the proportion of unsaturated fatty acids in their membranes, that is, increasing the proportion of saturated long-chain fatty acids.</u>
In addition to phospholipids, animals have an additional component in their membrane that helps them maintain fluidity. Cholesterol, another type of lipid that is embedded between the membrane phospholipids, helps decrease the effects of temperature on fluidity.
