<span>The correct answer is B. Lack of water. When there's no water and you start to dehydrate, your salivary glands start working extra hard because your mouth can't be dry and the salivary glands produce saliva to keep the mouth and the throat dry. If your throat and mouth are dry you can't even swallow.</span>

Gekata [30.6K]

Answer:

Prediction is correct.

Explanation:

In the body, transportation of molecules can occur in different ways or mechanism.

An example is by facilitated diffusion.

It is a passive form of transport where carrier proteins shuttle the molecule such as glucose into the cell without using energy.

Glucose being a large molecule is shuttled by glucose carriers across the cell membrane into the cell by facilitated diffusion.

Therefore an increase in the number of glucose carrier means an increase in the rate of glucose transport.

The results will show our prediction was correct.
