What do cells damaged by ultraviolet radiation result in?
It is suspected that this damage induces mutations that result in the development of malignant melanoma.
What happens to the tissues organs and organ systems if these cells are damaged or diseased?
The more damaged the cells are, the less efficient they will work. Your body will try to destroy these cells and replace them as quickly as possible. This largely depends on which cells are damaged, the extent, and the nature of the damage. Sublethal damage may result in accumulation of fluids or fatty degeneration. Lethal damage will result in necrosis, the death of the cell. When many cells are damaged, the surrounding cells may undergo mitosis, which is normal tissue growth. Necrosis can result in organ disease or failure.
Why are sunbeds unhealthy?
It is like standing next to a star. Sunbeds expose you to ultraviolet radiation and this can ionise your cells and damage them as it passes through your body. This is potentially harmful if too many cells get damaged as they can become cancerous and cause a tumour which can kill you.
How Can stem cells repair a damaged heart?
Stem cells can repair a damaged heart by turning into new cardiac cells to replace the damaged tissue.
How do hair cells in the ear contribute to damage and hearing loss?
Hair cells in the ear can be damaged by loud noises, aging, or certain medications. When these hair cells are damaged, they can no longer properly transmit sound signals to the brain, leading to hearing loss. This damage is often irreversible and can result in permanent hearing impairment.
What is a principle of the cell theory that supports the idea that new cells will replace damaged cells in a scraped knee?
The principle that states cells arise from pre-existing cells supports the idea that new cells will replace damaged cells in a scraped knee. When skin cells are damaged, nearby cells will divide to produce new cells to replace the damaged ones, adhering to the principle that new cells come from existing cells in the body.
What do you think will happen to the tissues organs organ systems if the cells were injured?
It will depend on which cells are damaged and the extent/nature of the damage. Sublethal damage is when the damage does not kill the cell. This may result in the accululation of water or another substance (eg. hydropic or fatty degeneration). If the cell is lethally damaged, it will undergo necrosis. If large areas of cells are damaged, the surrounding cells usually react by undergoing mitosis (depending on the tissue type in question). If large enough areas undergo irreversible damage, the tissue will become necrotic and organ disease or failure may result.

What allows growth and worn out or damaged cells?
Mitosis allows growth and replaces worn out or damaged cells.
Can damaged rods and cones heal?
No, damaged rods and cones in the eye cannot heal. Once they are damaged, the cells do not regenerate, which can result in permanent vision impairment. However, there are treatments available to help manage certain eye conditions and preserve existing vision.
What replaces dead or damaged cells?
Dead or damaged cells are replaced by nearby healthy cells that divide and multiply to fill in the empty space. In some cases, stem cells can also differentiate into the specific cell type needed to replace the damaged cells.
Damaged cells of an organism are usually by mitosis?
Damaged cells of an organism are usually repaired through the process of mitosis, where the damaged cell divides and produces two identical daughter cells. This allows for the organism to replace the damaged cells with healthy cells, maintaining proper functioning of tissues and organs.
