It could also treat niacin deficiency along with high triglyceride and cholesterol levels. Additionally, it can lessen the chance of a heart attack but also slow artery narrowing.

Niacin, sometimes referred to as nicotinic acid, would be a naturally occurring vitamin B_{3} found in the diet. It can raise blood lipid (fat) levels, including triglycerides and cholesterol, when used as medicine. In order to exert its effects, nicotinic acid causes the liver to produce less "bad" cholesterol and triglycerides.

The pictures represent three different states of matter.
juin [17]

Answer: Y → Z → X

Explanation:

The three states of matter shown in the picture are:

X) solid - in solids, molecules are bond together, so they are not free to move. They can only vibrate about their position - therefore they have the least freedom of motion

Z) liquid - in liquids, molecules are not bond, so they can move past each other. However, there are still strong intermolecular forces that keep the molecules close to each other, so they are not completely free to move - so this is the intermediate amount of motion

Y) Gas - in gases, molecules are completely free to move, since the intermolecular forces between them are negligible. Therefore, this is the state where molecules have the greatest amount of motion
