zysi [14]

Answer: D) Stereotyping

Choice A is false because this involves denying a person to do something based on factors such as religion, race, ethnicity, etc.

Choice B is false because this term involves a crime or suspected crime being committed, or about to be committed. And it also makes the assumption based on a person's race.

Choice C is false since segregation is the separation of people usually by race or ethnicity. Though you could have class based segregation (eg: rich vs poor) and other forms.

Choice D is true because stereotyping is where you lump a bunch of people together based on cultural or societal assumptions. Usually it's in the form of "all ___ people do such and such" where you fill in the blank with a specific race or culture.

aliya0001 [1]

Answer:

toward the 20% solute side of the membrane

Explanation:

that is the process of osmosis, in which the water moves in the direction that tends to equalize the solute concentrations on the two sides.

Basically it's to make it 50% 50%, so the water moves to the 20% solute side to raise the %

I hope it's clear enough.
