Question:

What is the difference between a polar and non-polar compound?

Lexye B.
Answer:

A polar compound is one that has one side that is partially charged positive and one side that is partially negative. This is due to the unequal sharing of electrons. Examples of these are water, ammonia, and hydrogen sulfide. A non-polar compound is a compound that is not charged. It shares its electrons equally between the elements. Examples of these are gasoline and toluene.

Question:

What is the part of the cell that is responsible for protein synthesis, packaging, and exportation?

Lexye B.
Answer:

The golgi apparatus is responsible for these things. There are two types of endoplasmic reticulum on the golgi. One is called the smooth endoplasmic reticulum (SER), and is responsible for synthesis of lipids, and the other is the rough endoplasmic reticulum (RER) which is responsible for the synthesis of proteins.

Question:

What is one distinguishing factor that determines whether you are looking histologically at an artery or a vein?

Lexye B.
Answer:

Arteries carry blood away from the heart to all other parts of the body, and veins return blood to the heart from all parts of the body. One distinguishing factor between an artery and a vein is that veins have thin non-elastic walls, whereas arteries have thick elastic muscular walls.
