Anvisha [2.4K]

Answer:

The entry of food into the stomach.

Explanation:

Gastric secretion is triggered by the act of eating which is called as reflex phase and the entry of food into the stomach called a gastric phase. The entry of the food particles into the small intestine also helps to control the secretion of gastric called an intestinal phase.

The secreted fluid in the small intestine contains some ions, acids, etc such as pepsinogen, intrinsic factor, bicarbonate, hydrochloric acid, and mucus. The reflex phase or cephalic phase helps to stimulate parasympathetic neurons that release acetylcholine chemical, then it produces the higher secretion of gastric juice.

A. A population with an annual growth rate of 3% doubles roughly every ____ years.
nikklg [1K]

Answer:

a.

3*x=100\\100/3=33.(3)\\\\

And you can round 33.(3) to 33.

b.

4*x=100\\100/4=25\\\\

and the final result is 25.

c.

7*x=100\\100/7=14.29\\\\

And you can round 14.29 to 14.

Explanation:

First of all, you have to find how many times the growth rate would multiply to get closer to 100%. So if you multiply 3 times 33 you'll get 99. So, a population with an annual growth rate of 3% doubles roughly every 33 years.

This solution is just for annual growth rate that is one year long.
