D) dilating sureface blood vessels

When you're out in cold weather, your skin triggers shivering so the blood vessels will contract and keep you as warm as possible. But if there's a heat wave, you'll sweat to increase the blood flow to the capillaries, which in turn increases sweating. This process cools you off as the water evaporates from your skin.

True or false: single sugars are too large to be absorbed directly into the bloodstream
AleksandrR [38]

Answer:

False

Explanation:

The sugars on the basis of the number of glucose or sugar units can be categorized into two categories:

1. Simple sugars: The sugars which contain one or two sugar units called mono and disaccharides.

2. Complex sugars: The sugars which contain more than two sugar units are complex sugars.

The simple sugars like glucose, galactose are easily digested by the digestive system of the human body and easily absorbed by the cells.

Since the simple sugars or simple sugars are small in their structure compared to the complex carbohydrates therefore false is the correct answer.
