What neurotransmitter is seen in excess after a stroke?
Glutamate is the neurotransmitter that is seen in excess after a stroke. This excess can lead to excitotoxicity, causing damage to brain cells and worsening the outcome of the stroke.
Does the sun give out natural highlights on light brown hair during the summer?
Yes, the sun can naturally lighten light brown hair during the summer due to its UV radiation breaking down the hair's pigment molecules. This process can create highlights or give the hair a sun-kissed appearance. It is important to protect hair from sun damage by using products with UV protection.
Why do old people get age spots?
Well this is because when we get older our skin starts stretching when this happens we get spots on us that our body doesn't catch up with its self and they called the spots liver spots then you get theses when your skin starts drying out those spots are brown the skin starts loosening up we bump or self's it can turn your skin red purple and tear the skin.Our skin isn't very strong.
How does vitamin e prevent aging?
Vitamin E is an antioxidant that helps protect cells from damage caused by free radicals. Free radicals can contribute to signs of aging such as wrinkles and sagging skin. By neutralizing free radicals, vitamin E can help prevent premature aging of the skin.
What is the reson of old age?
Old age is a natural result of the aging process, where the body's cells accumulate damage over time. This damage leads to a decline in physical and mental capacity, making individuals more susceptible to age-related diseases. The exact mechanisms behind aging are complex and involve a combination of genetic, environmental, and lifestyle factors.
How do melanocytes protect skin cells from UV damage?
Melanocytes produces melanin, the skin pigment that absorbs UV light from the sun and prevents it from damaging DNA in the cells.
How do UV rays contribute to the development of cancer?
UV rays can damage the DNA in skin cells, leading to mutations that can cause cancer to develop. UV rays can also weaken the immune system's ability to fight off cancer cells.
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.
What is the reason of incubating the UV-exposed cells in the dark environment?
cell that survive DNA damage due to the effect of the UV LIGHT only can growth in dark environment.
How does the sun cause damage to your body?
Uv rays kills the cells of the body and thus skin is burned -- prajakta
What does the ozone hole have to do with mutations in plants and animals?
Ozone in the upper atmosphere blocks (filters out) the harmfull UV components of sunlight which can damage DNA in cells. Where there is no Ozone the UV gets though and the damage caused to DNA results in mutations.
Do you need to wear goggles when using UV light?
Yes, you need to wear goggles when looking at UV light. It is highly penetrative and can cause damage to cells at the DNA level. Looking directly at UV can cause eye damage and it is imperative to limit exposure to it or wear goggles as a precaution.
How are humans adapted to UV rays?
Humans have evolved adaptations to protect against harmful effects of UV radiation. Melanin in the skin acts as a natural sunscreen, absorbing and scattering UV rays to prevent damage to skin cells. Additionally, repair mechanisms in cells help to fix any DNA damage caused by UV exposure.
How UV Light can break?
UV light has enough energy to break the chemical bonds in molecules, such as the bonds in DNA, causing damage to the structure of the molecules. When these bonds are broken, it can lead to mutations or cell death. UV light can also generate free radicals, causing oxidative damage to cells and tissues.
How does UV radiation cause skin cancer?
UV radiation causes skin cancer by damaging the DNA in skin cells. This damage can lead to mutations that can cause the cells to grow uncontrollably, forming cancerous tumors. UV radiation can also weaken the immune system's ability to repair damaged cells, further increasing the risk of skin cancer.
What is uv damage?
It is damage caused by the sun.
How does exposure to UV light affect the skin?
Exposure to UV light can damage the skin by causing sunburn, premature aging, and an increased risk of skin cancer. UV rays penetrate the skin and can harm the DNA in skin cells, leading to mutations and potential skin damage. It is important to protect the skin from UV exposure by using sunscreen and wearing protective clothing.
