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.

postnew [5]

Answer:

light is required to provide energy for photosynthesis

Explanation:

For photosynthesis to take place, it requires the presence of light and chlorophyll. The process has two stages; light and dark stage.

In the light stage, chlorophyll molecules absorb light energy which is used to split water molecules into oxygen and hydrogen atoms. The process is called photolysis.

water→ hydrogen atoms + oxygen.

The hydrogen atoms produced enter the dark stage while oxygen is released in the atmosphere. In the dark stage, carbon dioxide combines with the hydrogen atoms to form simple sugar such as glucose.
