For example, enzymes are proteins that speed up chemical reactions in the body and hormones, like insulin, are proteins that regulate the activity of cells or organs. Some proteins transport materials throughout your body, such as hemoglobin, which is the oxygen-transporting protein found in your red blood cells
Answer:
True
Explanation:
Elastic fibers are composed of elastin, myofibrils and fibrillin. They are distributed <u>separately</u>, and therefore do not form bundles(they actually form a kind of mesh), like collagen fibers.
Elastic fibers are usually thin and long and can stretch up to 1.5x of their total length.
These fibers confer elasticity to the connective tissue. The mesh formed of elastic fibers easily yields to minimal tensions, returning to its original shape as soon as the deforming forces cease.
An example of the action of elastic fibers is when we pull the skin from our hands and release it, the elastic fibers are responsible for quickly returning the skin to its original shape.
The correct answer is microbiology.

Microbiology is the branch of science that study microorganism. It contains a few sub-disciplines including virology (study viruses), parasitology (study parasites), mycology (study fungi) and bacteriology (study bacteria). Studied microorganism might be unicellular (one cell), multicellular (cell colony), or acellular (without cells).</span>
After break down food may be used in the body to provide energy, as building blocks for tissue and cells, and can be stored for future use.
The body uses food for energy, for growth by making new cells and repairing or replacing tissues, may be stored by converting it into glycogen or fat before they can be stored. The main types of foods are carbohydrates, proteins and fats.
The order of flow of oxygen within the human body may be described simply. Oxygen first is inhaled through the nasal cavity and then passes through the trachea, through the bronchi and into the lungs. In the lungs, the oxygen is passed into the blood stream through the alveoli and then is carried to the heart. The heart pumps this oxygenated blood throughout the body, primarily to organs and muscle cells, where it is consumed in respiration and is converted to carbon dioxide and excreted.
