Answer:
14). A. Prion
Many different diseases of animals and humans are caused by the pathological form of the prion protein (PrP). In animals, these disorders include scrapie of sheep and goats, "mad cow" disease, and chronic wasting disease of elk and deer. In humans, these maladies include kuru, Creutzfeldt–Jakob disease (CJD), Gerstmann–Sträussler–Scheinker disease (GSS), and fatal familial insomnia (FFI).
15). C. It activate the immune system to fight off infection parasites
A higher body temperature accelerates the internal workings of cells. This means disease-fighting cells respond faster, and immune responses increase. Germs, on the other hand, don't reproduce as well at higher temperatures. A very high fevercan slow down or kill off the microbes that cause some infectious diseases.
16). A. the ability of an organism to maintain constant internal conditions.
17). A. Osmosis
The movement of water molecules from a region of lowconcentration solution to high concentration solution through semipermeable membrane is called osmosis
18). C. 5
