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 correct answer is c. water to move out of the strawberry, making it smaller
Explanation:
Osmosis is the process refers to the movement of liquid molecule from the area of high solute concentration to an area of low solute concentration through a semipermeable membrane to equalize the osmotic balance.
Osmosis is important for any cell to maintain a proper osmotic balance of the cell. So if sugar is sprinkled on a strawberry the solute concentration outside the strawberry cells will increase which will result in water release from the cell.
This release of water from the cell will shrink the strawberry and make it small. Therefore the correct answer is c.
It constantly moves to readjust the position of the eye.<span>It constantly moves to maintain a steady point of fixation.</span>
You need to draw a food chain starting with something small like bacteria and and getting back around the loop to bacteria again( explaining what the the previous organism does to the next for example it eats it). Then you need to underline the organisms/animals. Then write in bold the way it got the energy from the previous one( for example if it eats it )
