Question

GUYS AND GIRLS I NEED HELP PLZ!!!

Insulin is an important hormone that allows the body to use glucose from food. After an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. The glucose causes the beta cells to release insulin. Insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy.

What does this information best demonstrate?

A.
A hormone is a protein that performs many functions in the body.
B.
Cells interact with other cells for regulation and homeostasis.
C.
Beta cells are not necessary for glucose to be utilized.
D.
Only certain cells can use glucose to produce energy.

i think the answer is b

Answer 2

The answer is; B.

Cells have different receptors on their surfaces that are responsive to particular signals (such as hormones). When a signal interacts with the particular receptor, a particular response is invoked in the cell. This signal may be produced even by a cell that may be far away from the target cells. This is how cells communicate with each other to maintain homeostasis in the body.
