Before the marble starts rolling, it is potential energy. Once it is rolling, it is kinetic energy. You know it stays the same because the marble probably would not be rolling if it weren't. All that's happening is that the ball is rolling faster because of gravity.


<span>Gravity assists the marble, leading to conservation of energy. The stored energy is release as momentum, the output of energy is constant.</span>

A human eats a meal and afterward their blood glucose levels rise. Explain how the human body responds to return their blood glu
Nookie1986 [14]

Answer:

Explanation:

The bloodstream carries glucose-a type of sugar produced from the digestion of carbohydrates and other foods-to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen.

Insulin , glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range. Too little or too much of these hormones can cause blood sugar levels to fall too low (hypoglycemia) or rise too high (hyperglycemia).

Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal. When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal

Which statement best describes how a catalyst can speed up a chemical reaction? The catalyst decreases the reaction energy neede
beks73 [17]

Answer:

The catalyst decreases the reaction energy needed.

Explanation:

The catalyst speeds up chemical reactions by decreasing the amount of activation energy/reaction energy needed in the reaction.

Compared to reactions without catalysts, they are much faster because there is less activation energy needed.
