(PLSSS DO THIS ILL MARK BRAINLESS) Matter on Earth constantly cycles between the different reservoirs of the Earth system. As matter cycles through the Earth's reservoirs, what effect does this have on the total amount of matter on Earth?
A.
The total amount of matter on Earth constantly decreases.
B.
The total amount of matter on Earth is always changing.
C.
The total amount of matter on Earth constantly increases.
D.
The total amount of matter on Earth remains constant.

The total amount of matter on Earth constantly increases.

Explanation:

This is because there are always new things taking birth every second and they have matter in them, so the matter is increasing constantly.

The answer is D. The total amount of matter on Earth remains constant

Explanation:

I just did this and its the correct outcome :/ Hope it helps

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
