Why are tobacco and alcohol and ultraviolet radiation listed as carcinogens?
It could be connected somehow with the fact that tests, studies, and surveys over forty years and thousands of subjects have demonstrated that regular tobacco use, excessive consumption of alcohol, and excessive exposure to UV are all linked to the increased occurrence of certain types of cancers, and that the increase is statistically significant to a degree that these factors may realistically be called 'causes'.
Can a light bulb make you sick?
Exposure to light during the night can affect melatonin level in the body and disrupt sleep, which is not healthy. Low levels of melatonin in the body may be linked to cancer. Also, certain colors can cause health problems. Excessive exposure to blue light can lead to early macular degeneration in the eyes, one of the major causes of blindness in the elderly. Excessive exposure to UV light, such as from tanning bulbs, can cause sunburn, aging of the skin, eye injury, and even skin cancer.
Which type of inheritance involves traits linked to a sex chromosome?
It is called sex-linked inheritance. If the sex-linked gene is on the X sex chromosome, it is often called X-linked inheritance.
What is miosis-?
Miosis is constriction of the pupil of the eye. It is the normal reaction to an increase in the amount of light entering the eye, but can also be linked to pathological conditions, microwave radiation exposure and certain drugs.Please see the related question "What is Meiosis?" for information on cell division. Also, see "What is Mitosis?".
What would happened if the ozone layer vanished?
If the ozone layer vanished, we would all die. With no ozone, ultraviolet rays (UV-B specifically) are easily able to penetrate the earth's atmosphere and exposure to UV-B rays has been linked to the increased occurrence of cancer, cataracts, mutation, and decreases in crop yields and loss of arable land. This affects Man and all DNA-based life on the surface of the Earth. An essential part of the atmosphere is the ozone layer. It is very important for life on earth. The atmosphere absorbs ultraviolet solar radiation, and moderates temperature.
How is radiation linked to birth defects?
RADIATION. Exposure of the mother to high levels of radiation can cause small skull size (microcephaly), blindness, spina bifida, and cleft palate. How severe the defect is depends on the duration and timing of the exposure.
What disease is excess fat linked to?
Cancer
How radiation is linked to chernobyl and hiroshima?
A nuclear bomb was dropped on Hiroshima in 1945. And in 1986 a nuclear accident occurred at Chernobyl. That's why radiation is linked with either of them.
What type of light is most dangerous to the back of the eye?
The sun's primary danger to us comes in the form of UV light or radiation. UV radiation is a component of solar radiation. Artificial sources like welding machines, tanning beds, and lasers can also give off UV radiation. There are three types of UV radiation. UV-C is absorbed by the ozone layer and does not present any threat. UV-A and UV-B radiation can have adverse long- and short-term effects on the eyes and vision. Both long- and short-term exposure to UV radiation can harm the eyes, affect vision, and compromise overall eye health. There are several eye diseases and conditions caused or aggravated by exposure to UV radiation: Macular Degeneration. Cataracts.. Pterygium. Often called "surfer's eye." Skin Cancer. Skin cancer in and around the eyelids is also linked to prolonged UV exposure. Photokeratitis. Also known as corneal sunburn or "snow blindness."
Can sleeping on your cell phone affect your body?
Recent studies have linked sleeping near your cell phone to lack of sleep. Most cell phones have 884 MHz wireless signals ...emitting radiation. One study, done by M.I.T exposed subjects to "mobile phone radiation" as they were about to sleep. Many phones have 884 MHz wireless signals, which have been linked to affecting one's sleep. Cell phone radiation exposure during the night can reduce one's ability to recuperate from a stressful and difficult day.
What factors are associated with causing cancer?
cigarette smoke, air and water pollution, and exposure to ultraviolet radiation from the Sun increase the risk of cancer.
Why do people who work outdoors at greater risk of getting skin cancer?
The main principle behind this claim is that outdoor workers have a greater exposure to the sun. Excess exposure to the sun has been linked to melanoma and other skin cancers. The sun releases ultraviolet (UV) radiation which is harmful in large doses. UV rays are classified into UV-A, UV-B, and UV-C, all of which can contribute to skin cancer. UV rays travel like any ordinary waves and can penetrate into the skin. A chemical in the skin called melanin, which pigments skin, absorbs some of the UV radiation to protect the body. Sunburn occurs when the UV radiation exceeds the amount melanin can absorb. As with any ionizing radiation, it can cause the genetic codes and cells to undergo a mutation, causing cells to change functions and in some cases divide uncontrollably. If you work outdoors, it is vital you protect yourself from excess sun exposure. Always find shade if possible, apply SPF 30+ sunblock lotion, wear a hat, wear UV safe sunglasses and cover exposed body parts. Any mole or freckle that changes its shape, size of colour should be reported immediately to your medical doctor for evaluation. If you suspect any abnormal skin changes, have it checked by a medical doctor for possible skin cancer.
What is the maximum amount of radiation a human body can tolerate?
100 milliSieverts is the smallest radiation dose clearly linked to cancer. 1 Sievert is the smallest radiation dose required to induce radiation sickness. The average person absorbs 250 millirems over a lifetime.
What are the risks linked with working with uranium?
Uranium is radioactive, direct exposure can lead to cancer as well as other birth defects.
Which of the following has not been linked to causing cancer carotenoids high fat diet UV radiation viral infection?
carotenoids
Waht is a sex-linked condition that more often affects males?
color blindness
Is the pyramid on the dollar bill linked to a cult?
Possibly, but it is considered a conspiracy theory to nonbelievers. There is quite a bit of exposure of this topic. Look up illuminati on youtube.
