What else can I help you with?
Do liver cells usually undergo cell division?
No. Only yo repair minor damage to the liver.
When water leaves the cell the cell will?
When water leaves the cell, the cell will shrink or shrivel up due to loss of water, a process known as plasmolysis. This can affect the cell's ability to function properly and may lead to cell damage or death in extreme cases.
What is p53 and how does it work?
p53 is a tumor suppressor gene that helps to control cell growth and prevent cancer development. It plays a critical role in protecting cells from DNA damage by either repairing the damage or inducing cell death if the damage is severe. When activated, p53 can signal for cell cycle arrest, DNA repair, or apoptosis (programmed cell death) to eliminate cells with irreparable damage.
Which of the following cell types are least sensitive to ionizing radiation damage?
Red blood cells are the least sensitive to ionizing radiation damage because they lack a nucleus and are unable to repair DNA damage caused by radiation exposure. This also makes them unable to undergo cell division or replication.
What checks for cell damage during the Cell Cycle?
The p53 tumor suppressor protein plays a key role in monitoring cell damage during the cell cycle. If DNA damage is detected, p53 can halt the cell cycle to allow for repair or trigger apoptosis if the damage is irreparable.
Why is the function of mitosis cell division is dangerous to the heart?
This is because mytotic cell division does not occur in the heart, so if damage is done the cells in the heart cannot repair themselves.
How does a cell know when to carry out mitosis and when not to carry out mitosis?
Cells regulate the cell cycle through checkpoints that monitor cell conditions. Factors such as DNA damage, cell size, and growth signals determine whether a cell should proceed with mitosis or pause the cell cycle to repair damage. If conditions are not favorable, the cell will not enter mitosis.
What part of the cell is particularly at risk from exposure to ultra-violet rays?
The cell's DNA is particularly at risk from exposure to ultra-violet rays. UV radiation can cause damage to the DNA structure, leading to mutations and potential cell death. Cells have mechanisms to repair this damage, but excessive exposure can overwhelm these repair processes.
Why the formation of calluses on the hands provides evidence that cell division can be stimulated by cell damage?
calluses on the hands provides evidence of cell damage because if you are using your hand doing a lot of heavy lifting, or gripping something too hard it could cause calluses. It begins to turn yellow or white, and the area becomes hard. It can kill or damage the cells which could be harder for the cell division to take place. Cell division works faster to hear the damage. Mitosis helps repair skin tissue.
When plant cells are exposed to salt water what happens to them?
When plant cells are exposed to salt water, they undergo plasmolysis due to the higher concentration of salt outside the cell. This causes water to move out of the cell, leading to the cell membrane pulling away from the cell wall. This can result in wilting and potential damage to the plant cells.
Why are checkpoints important to the health of the cells?
Checkpoints are important in cell cycle regulation as they ensure that each phase of the cell cycle is completed accurately before progressing to the next phase. Checkpoints help to prevent the proliferation of damaged or mutated cells, thus maintaining cellular health and preventing the development of diseases like cancer. They enable cells to repair DNA damage or induce apoptosis if the damage is too severe for repair.
What cells that are placed in a hypertonic solution of pure water tend to?
Cells placed in a hypertonic solution of pure water will tend to lose water and shrink due to the higher concentration of solutes outside the cell causing water to move out of the cell by osmosis. This can lead to dehydration and potential cell damage.
