Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
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.
