your skin replaces itself about every 30 days, everything else is replaced in cycles that take somewhat longer than that
if the cells are permanently mitotic the are not able to repair them selves.
Organisms need new cells for growth, repair, and to replace old or damaged cells. Cell division allows organisms to produce new cells that are needed to maintain and support bodily functions. Without new cells, organisms would not be able to grow, heal, or maintain proper functioning.
Mitochondria can replicate themselves. They also have own ribosomes.
If all of your cells stopped reproducing, your body would not be able to replace damaged or dead cells, leading to tissue degeneration and organ failure. This would ultimately result in death. Cell reproduction is essential for growth, repair, and maintenance of the body's functions.
Cancer cells are able to take over healthy cells due to multiple mutations in the genes. When the healthy cells become cancerous, the genetic information will be damaged and destroyed.

no
No, otherwise you would see para and quadriplegics getting better.
The gene BRCA1 helps repair damaged DNA in cells, which can prevent the growth of abnormal cells that could lead to breast cancer. Mutations in the BRCA1 gene can increase the risk of developing breast cancer because the cells may not be able to repair DNA damage properly.
If the myelin sheath is able to repair and regenerate itself, normal nerve function may return. However, if the sheath is severely damaged, the underlying nerve fiber can die.Because nerve fibers in the central nervous system (brain and spinal cord) rarely regenerate, such damage is irreversible.
Cells that rapidly divide are most sensitive to ionizing radiation damage, including stem cells, progenitor cells, and cells of the gastrointestinal tract, bone marrow, and skin. These cells have higher metabolic activity and are less able to repair damaged DNA compared to more differentiated cells.
Certain neurons can repair themselves while others can't. Neurons that can repair themselves are refreed to as white matter. The reason white matter can repair itself is because the axons of white matter are myelinated. The axons of neurons in grey matter on the other hand, cannot repair themselves because they are unmyelinated.
Amitosis is the condition where cells don't divide, so the organ wouldn't be able to replace any of its cells.
if you don't sleep enough then you won't be able to focus and you will irritableAnswer:Sleep helps to rest and repair the brain. The more hours that an individual stays forcibly awake, the more that damaged brain cells are suspended from repair. Read on the related link on how this was determined by an experiment in University of Wisconsin.
