Exposure to UV radiation can lead to damage in living tissues by causing sunburn, skin aging, and an increased risk of skin cancer. UV radiation is absorbed by the DNA in cells, leading to mutations that can disrupt normal cell function and potentially lead to cancerous growth. It is important to protect the skin from excessive UV exposure by using sunscreen and seeking shade when outdoors.
What else can I help you with?
What are the three types of UV rays and their effects?
The UV rays are of three types. they are UV-A, UV-B, UV-C.
What happens to ultra violet rays as they reach earths surface?
As ultraviolet (UV) rays from the sun reach Earth's surface, a significant portion is absorbed by the ozone layer in the stratosphere, which protects living organisms from harmful effects. The remaining UV radiation that reaches the surface is primarily UV-A and a smaller fraction of UV-B, both of which can cause skin damage and increase the risk of skin cancer. Additionally, UV rays can contribute to environmental effects, such as affecting ecosystems and degrading materials like plastics.
How does ozone interact with the sun?
Ozone absorbs ultraviolet (UV) radiation from the sun, preventing most of it from reaching the Earth's surface. This absorption of UV radiation by ozone forms a protective layer in the Earth's stratosphere, which shields living organisms from the harmful effects of excessive UV exposure, such as skin cancer and cataracts.
Why can't clinical trials be done on human tissue samples only?
The tissue samples are not alive. They are not growing/moving like a living human so the effects the drugs have on the non living samples may be different to the effects on a living human.
How ozone effects living things?
It irritates the Eyes, throat, lungs. It can also harm plants and other living things and damage many materials. It absorbs UV-B or more energetic light, that would otherwise reach Earth's surface. UV-B damages DNA, passing through skin (or leaf structures) that is transparent to UV-B.
What is a list of the effects of ozone depletion?
The ozone depletion makes UV rays enter the earth. UV rays are fatal for living organisms.
What are the three types of UV rays and their effects?
The UV rays are of three types. they are UV-A, UV-B, UV-C.
What happens when you put eye drops when you're on LSD?
LSD is potent in such very small quantities that it can have significant effects when it comes in contact with skin, which is dead tissue. If it is capable of absorbing through dead tissue to living tissue in large enough quantities to have effects, then it is certain to have effects when put on living tissue, which has much closer contact to the bloodstream and therefore the brain. In short, it certainly will, even in very small quantities.
Why clinical trials can't be done on human tissues?
The tissue samples are not alive. They are not living or moving like a living human. The effects of the drugs may be different on 'non living' samples may be different to the effects on a non-living human.
What are the useful effects of ultraviolet rays of the sun?
Useful effects of UV are also there. Filters, locks etc use UV.
What effect is ultra violet rays having on life here on earth?
UV has adverse effects. It can cause skin cancer to living organisms.
What are the effects on the destruction at the ozone layer on living things?
Destruction of ozone can cause UV rays to come in. This can even cause global warming.
Is it bad for a scar to have UV rays shining on it?
UV is no worse for scar tissue than for normal skin.
What happens to ultra violet rays as they reach earths surface?
As ultraviolet (UV) rays from the sun reach Earth's surface, a significant portion is absorbed by the ozone layer in the stratosphere, which protects living organisms from harmful effects.

Additionally, UV rays can contribute to environmental effects, such as affecting ecosystems and degrading materials like plastics.
What layer in the earths atmosphere blocks out harmful rays from the sun?
The ozone layer in the Earth's stratosphere blocks out harmful ultraviolet (UV) rays from the sun. It absorbs most of the sun's UV radiation before it reaches the Earth's surface, protecting living organisms from the harmful effects of UV exposure.
How does ozone interact with the sun?
Ozone absorbs ultraviolet (UV) radiation from the sun, preventing most of it from reaching the Earth's surface. This absorption of UV radiation by ozone forms a protective layer in the Earth's stratosphere, which shields living organisms from the harmful effects of excessive UV exposure, such as skin cancer and cataracts.
Why clinical trials can't be done on human tissue samples only?
Clinical trials require studying the effects of a treatment in a living organism to understand its overall impact, including potential side effects and interactions with other bodily systems. Human tissue samples lack the complexity of a functioning organism, meaning that critical information about how a treatment interacts with the body as a whole would be missed.
