<span>Homeostasis Body's tendency to maintain a steady internal state; physiological equilibrium or balance around an optimal set point. [hot=sweat, cold=shivers]
Janice sweating on the treadmill in order for her body to cool off is an example of Homeostasis. Homeostasis is the body's ability to keep a steady internal temperature, state, equilibrium or balance around the ideal set point. This means when you are hot, you sweat to cool the body down and when you are cold your body shivers to help warm it up.</span>
Answer:
False
Explanation:
Restriction enzymes, also called restriction endonucleases, are enzymes found in bacteria that cut DNA. They recognise target sequences and cut DNA at or near these sequences. These sequences are called restriction sites.
They act as a defense mechanism against invading pathogens. However, they are routinely used in molecular biology labs to perform DNA technologies such as genetic engineering.

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.
