The DERMIS, especially the deep reticular layer of dermis, is composed of DENSE IRREGULAR connective tissue.
Dense regular connective tissue is composed of tightly wound fibers of collagen, mainly found in tendons and ligaments.
A high pressure system has higher pressure at its center than the areas around it. Wind blows away from high pressure. Winds of a high pressure system swirl in the opposite direction. But a low pressure system - clockwise north of the equator and counterclockwise south of the equator.
The answer is ribose.
mRNA is actually messenger ribonucleic acid. As any other RNA (ribonucleic acid) it consists of a phosphate group, sugar ribose, and nucleobases (adenine, uracil, cytosine, guanine). So, it is called RIBOnucleic acid because it consists of sugar RIBOSE.
Take for example DNA - deoxyribonucleic acid. It is called DEOXYRIBOnucleic acid because it consists of sugar DEOXYRIBOSE.
