Answer:
<u>Nerve. All the three heads of triceps brachii are innervated by the four branches of the radial nerve (C7, C8). However, according to the cadaveric study it is found that the medial head of triceps brachii is innervated by the ulnar nerve</u>
Explanation:
14. Surface Area , and Volume Area limits the size of cells.
15 .A cell is a metabolic compartment where a multitude of chemical reactions occur. The number of reactions increase as the volume of metabolic volume within a cell increases. (The larger the volume the larger the number of reactions)
All raw materials necessary for metabolism can enter the cell only through its cell membrane.
The greater the surface area the larger the amount of raw materials that can enter at only one time.
Each unit of volume requires a specific amount of surface area to supply its metabolism with raw materials. The amount of surface area available to each unit of volume varies with the size of a cell.
As a cell grows its SA/V decreases.
At some point in its growth its SA/V becomes so small that its surface area is too small to supply its raw materials to its volume. At this point the cell cannot get larger.
16. Cells only divide when they receive specific signals from proteins called mitogens,the presence of mitogens can limit cell division. Mitogens are needed for cell division in healthy cells and are released depending on what cells the body needs.
Answer:
While many microbes are harmless to humans, others can cause serious problems. They can spoil food, introduce toxins, cause disease and lead to a host of other problems. The importance of microbiological testing is to quickly identify these contaminants and treat them before they do irreversible damage.
Explanation:
Aerobic bacteria are bacteria that can grow and live when oxygen is present.
