Why does exposure to uv radiation cause death in vegetative cells but not endospores?
UV radiation causes damage to the DNA of vegetative cells, leading to cell death. Endospores, on the other hand, have a protective protein layer that shields their DNA from UV radiation damage, allowing them to survive exposure. This difference in DNA protection is why endospores are more resistant to UV radiation compared to vegetative cells.
Which cells of the body are most susceptible to radiation damage?
thyroid gland is one of the most sensitive organs..
How is brain surgery done?
There are several brain cancer treatments. These include: radiation, chemotherapy and clinical trials. Radiation therapy is the use of high-energy rays to kill tumour cells and stop them from growing and multiplying.
Do night lights kill brain cells?
Unless the light sources emit harmful forms of radiation such a X-rays or Gamma-rays the answer is no, they do not!
What is the definition of a radio resistant tumor?
the tumor is not effected by radiation
What form of radiation can humans see?
Humans can see visible light, which is a form of electromagnetic radiation with wavelengths between 400-700 nanometers. This range of wavelengths is detected by the photoreceptor cells in our eyes and processed by the brain to produce the sensation of sight.
Is brain a most radiosensitive tissue?
The brain is not considered the most radiosensitive tissue in the body; instead, it has a relatively low sensitivity to radiation compared to other tissues, such as bone marrow or the gastrointestinal tract. The central nervous system, particularly neurons, has limited capacity for regeneration, which can make damage from radiation more critical. However, glial cells, which support neurons, can be more affected by radiation. Overall, while the brain can be impacted by radiation exposure, it is not the most radiosensitive tissue.
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.
Can a microwave kill your brain cells?
No, using a microwave as intended to heat food will not kill brain cells. Microwaves emit non-ionizing radiation, which does not have enough energy to cause damage to cells in the body. It is safe to use a microwave for cooking purposes.
Are there cells in the brain?
Yes. They are called, ironically, brain cells.
What kind of cells are in the brain?
Neurons are brain cells
How many cells in the human brain?
There are over 400,094,800 cells in the human brain, while the entire body has about 50 to 75 trillion cells.
