How is the behaviour of cancer cells different from that normal cells?
Cancer cells have the ability to grow and divide uncontrollably, whereas normal cells grow and divide in a regulated manner. Cancer cells can also invade surrounding tissues and spread to other parts of the body, a process known as metastasis, which normal cells do not do. Additionally, cancer cells may evade the body's immune system and resist cell death signals that would normally eliminate damaged cells.
In what parts of your body does mitosis not occur?
Within the body's cells.This is true but very vague. Mitosis occurs in all of the bodys cells that are somatic, meaning any cell that is notproduced in an organisms sex organ. The (daughter) cells that are produced are genetically identical to their (Parent) cell. These cells are produced for the purpose of replacing old or damaged cells in order to prevent disease, as well as growth and repair.
Do the nerve cells divide?
Most nerve cells do not divide in adulthood, with few exceptions such as olfactory neurons and certain neurons in the hippocampus. The majority of nerve cells are post-mitotic, meaning they lose their ability to undergo cell division after development.
Why do all human cells divide at the same rate throughout life?
They don't. Some grow and divide all the time (skin cells) and some never do (nerve cells) and some only at times when needed.
Certain eye stem cells can only differentiate into a few types of eye cells what kind of stem cells is this?
Multipotent
Not all cells divide or repair themselves?
That's correct. Nerve cells, for example, typically do not divide or repair themselves once they are damaged. This lack of division contributes to the challenges in regenerating nerve tissue after injury.
Why is it advantages for a cell to grow only to a certain size and then divide into two smaller cells?
Cellular division is the cellular equivalent of reproduction. It is how cells reproduce.
Why is it advantageous for a cell to grow only to a certain size and then divide into two smaller cells?
Smaller cells work more efficiently because their "supply lines" are short.

Why is it good to have dead cells on the surface of the body?
If only the first layer of cells is damaged, then only the dead cells will be affected (and fall off). This acts as protection for the newer cells underneath.
Why does a skin cell divide more often than liver cell?
As far as I know, liver cells usually only undergo mitosis if the liver is damaged. You should check a few other sources though.
The reason only certain cells are affected is that the membranes of these cells have specific?
receptors
What type of cells in the body perform mitosis?
Most cells in the body are capable of undergoing mitosis, with exceptions such as mature red blood cells and certain brain cells that are terminally differentiated and do not divide. Skin cells, gut cells, and immune cells are examples of cells that regularly undergo mitosis for growth, repair, and maintenance of tissues.
Do blood cells undergo meiosis?
no. only the cells in the gonads which are to become gametes undergo mitosis. blood cells, like all cells but gamete cells are called somatic and only divide by mitosis.

Can Bacterical cells didvide by mitosis?
That's about the only way they divide I believe.
