Cells will generally divide when they receive specific signals indicating that growth or repair is needed, such as growth factors or hormones. Additionally, they must have adequate resources, such as nutrients and energy, to support the division process. The cell cycle checkpoints also play a critical role, ensuring that conditions are favorable and that the cell is ready to proceed with division.

What are the cells in your body that no longer divide in?
The cells in the body that typically no longer divide are called terminally differentiated cells. Examples include neurons in the brain and cardiac muscle cells, which have exited the cell cycle and generally do not undergo mitosis after reaching maturity. While some tissues can regenerate through stem cells, these specialized cells are generally considered to be in a permanent state of growth arrest.
Which cell type is least sensitive to ionizing radiationcells that don't have nucleus cells that are activiely dividing cells that divide slowly or cells that don't divide?
Cells that don't have a nucleus, such as red blood cells, are generally the least sensitive to ionizing radiation. This is because they lack the DNA that is typically damaged by radiation. In contrast, actively dividing cells and those that divide slowly are more sensitive due to their higher levels of DNA synthesis and repair processes. Cells that don’t divide at all are also less sensitive, but not as much as anucleated cells.
What are three 7th grade reasons cells divide?
cells divide because of: -growth -development -repair
How long would it take for 2 bacteria cells to divide and turn into 4 bacteria cells?
In ideal conditions, bacterial cells typically divide through binary fission, a process that can take about 20 minutes to a few hours depending on the species and environmental factors. So, it would generally take around 20 minutes to several hours for two bacterial cells to divide and become four cells.
What is it called with the cell divide to create new cells is called?
It is called mitosis when regular cells divide. It is called meiosis when sex cells divide.
What type of cells divide by mitosis?
somatic cells are generally in humans

Cells that no longer divide are called what?
Cells that no longer divide are called senescent cells. Senescence occurs when the telomeres found in the DNA of organisms become too short.
When we grow do our cells grow or divide?
Cells divide.
Human cells that do not divide?
Some human cells that do not divide include nerve cells (neurons) and cardiac muscle cells. These cells have limited or no capacity for cell division due to their specialized functions and mature state. Once these cells are fully developed, they generally do not undergo cell division.

Do skin cells divide?
yes. all skin cells divide and divide and divide all over your body.
Why do divide?
There are numerous reasons why cells divide. If someone skins their leg, for example, cells will divide for the purpose of replacing cells that have been damaged.
What are three 7th grade reasons cells divide?
cells divide because of: -growth -development -repair
Is it important for cells to divide?
If cells do not divide properly, then many problems can occur, cancer cells for example.

Which type of cells do not divide?
Nerve cells, also known as neurons, do not divide.
