If an individual has an <u>increased</u> rate of blood flow to the skin,such as would happen with emotion or alcohol consumption ,their skin takes on a <u>reddish</u> tinge.
Explanation:
Our skin is provided with a large number of blood capillaries. These capillaries bring blood and nutrients to the layers of skin. Whenever vasodilation of these capillaries occur, the blood flow to the skin increases and the skin gets a reddish tinge.
During an emotional upsurge such as embarrassment causes the adrenal glands to release adrenaline.
Adrenaline as well as alcohol vasodilates the blood vessels and increases the flow of blood to the skin. Hence, the skin gets a reddish tinge.
The answer is actually false, i just took the test

Answers:
1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.
2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.
3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.
Step-by-step explanation:
Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.
Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.
Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.
