Skin cells, divide in a continuous manner that makes new skin cells to replace the skin cells we lost. Cells regulate their division by cyclins. Some cells divide faster when it supposed to stop dividing and this will lead to cancer disease.
<u>Explanation:</u>
The process of cell division occurs for many reasons. A single cell is divided into two which in turn they will be divided into four and so on. This corresponds to the process of cell division and cell reproduction. Cell division is an unique characteristics in human beings. Interactions between signaling proteins produces checkpoints in the cell cycle to ensure that cells do not divide at improper times.
A protein named Cyclins plays a major role in the determination and the regulation of the cell division process. The division that occurs in the cell can be regulated by the this protein type. They acts as a switch for controlling the cell division process. They will signal the cells when to divide and when to stop. When any cell continues to divided even after it is signaled to stop they may lead to a disease called cancer. These are different form the normal cells because they will be having their own growth factors that controls their growth and they will lose the normal controls on the cell cycle.

Answer:
The second picture showing big rocks with the gaps between where they touched empty.
Explanation:
The figure shown in picture 2 will be the most porous as it does not comprise of any blocking particles. I t will be well sorted and will allow small molecules to easily pour through it.
On the other hand, the other figures like figure 3 will not have much porosity as the path is blocked by many large and small rocks in the image. Hence, it is not the correct option.

are part of the brain that shows a larger surface of the brain. When the gyri
change in structure or form it shows that a body is encountering sickness and

If you must leave an injured or ill athlete unattended to get additional help, and you do not suspect an injury to the head, neck or back, then you should ask not to move while going for help, either by calling 911 or looking for someelse to help, once contacted help return immediately with the injured person and check that no threat has appeared to his life and provide care while the help gets there.
