Answer:False
Explanation:
Acid rain is an indirect result of burning fossil fuels Acid rain occurs when sulfur dioxide and nitrogen dioxide are released into the atmosphere due to incomplete combustion of fossil fuels. Each of these oxides is mixed with rainwater to form sulfuric acid and nitric acid. Thus, acid rain is in fact an indirect result and is not a direct result of the release of acid when burning fossil fuels. This is because oxides are formed during combustion.
Hey there!
Let's start with the first blank. The ozone layer starts in the stratosphere and is made of ozone gases made to protect the Earth from the Sun's harmful UV rays. If the ozone layer wasn't there (not to mention the rest of the atmosphere), we would be exposed to that kind of radiation. Thereofe, "Ultra violet rys would not be <u>blocked</u> by the ozone layer."
For the next one, a lot of levels of substances in the air would change, like UV and oxygen- as there would be more radiation from the lack of protection and all the oxygen would escape.
Hopefully this helps!
The value of x = 4
<u>Explanation:</u>
RS = 4(x-3)+6
= 4x-12+6
= 4x-6
RT = 5(2x-6)
= 10x-30
Showing left hand side is equal to right hand side.
4x-6 = 10x-30
Divide both left hand side and right hand side by 2, we get:
2x-3 = 5x-15
Rearrange both the sides
-3+15 = 5x-2x
12 = 3x
x = 4
Thus, the value of x is 4
This is a type of protein found in the cell membrane, which regulates the coming and going of substances into or out of the cell.

Answer:
a population is the entire pool from which a statistical sample is drawn. A population may refer to an entire group of people, objects, events, hospital visits, or measurements. A population can thus be said to be an aggregate observation of subjects grouped together by a common feature.
