All of the following are health benefits of soluble fiber except
a. normalizes blood glucose
b. delays gastric emptying
c. reduces serum cholesterol
d. stimulates appetite

d. stimulates appetite

Explanation:

The soluble fiber is the one that dissolves in water, and its main characteristic is the delaying gastric emptying, they made you feel full for hours because it creates a viscosity gel that stays in the colon.

This gel covers the colon and prevents gastritis, and get the sugar absorption and realizing slower.

Also, use serum cholesterol, and this is why it helps to reduce heart cardiopathy disease.

d. stimulates appetite

Explanation:

Soluble fiber is known to suppress appetite and the suggested ways in which it does this is by:

1) Slowing bowel movement.

2) Controlling the release of sugar in the blood, more slowly. Insulin will also be released slowly thus decreasing the sense of hunger.

3) Regulating hormones involved in hunger control such as ghrelin.

4) Increasing hormones that make one feel full, such as cholecytokinin, GLP-1 (glucagon-like peptide 1) and peptide YY.    

the areas around the equator

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
