The reason why some people are more sensitive than others comes down to how our body modulates pain from the skin to the brain and the structure of the brain itself. It all begins with a bunch of sensory receptors detecting an unpleasant stimuli. These are transformed into pain signals that are then conducted throughout the central nervous system via a series of 'pain pathways'.
-Ultraviolet (UV) exposure – The sun is the most well-known source of UV radiation, but UV rays also come from tanning beds and other artificial sources.
-Genetics – Some risk factors of skin cancer can be inherited through our DNA.
-Immunosuppression – Some conditions, like AIDS, and certain medications, such as those provided after organ transplants, can suppress the body’s immune system and might contribute to the development of skin cancer.
-Radiation exposure – In addition to UV, there are other forms of radiation that may adversely affect the skin cells, such as X-rays or therapeutic radiation.
-Toxic sunscreens -- Most sunscreens block the absorption of Vitamin D with toxic chemicals that seep through the skin and into the bloodstream and all throughout your body. Using these toxic sunscreens could actually cause cancer. Some toxic ingredients that are in these kinds of sunscreens: oxybenzone. benzene, parabens, homosalate, octinoxate, and octocrylene
Caucasians are more at risk for skin cancer because they have less melanin produced in their skin. Lighter skin tones produce less melanin and are more prone to damaged DNA particulate from UV radiation.
Answer:
Una suspensión es una mezcla heterogénea que contiene partículas grandes que se asientan por gravedad. La arena en agua es un ejemplo de una suspensión. Una solución es una mezcla homogénea de dos o más sustancias donde una sustancia está disuelta en la otra.
Explanation:
Una mezcla homogénea es aquella en la que sus componentes están mezclados de forma tal que es imposible diferenciarlos a simple vista, estando distribuidos de manera uniforme. ... Por el contrario, los elementos de una mezcla heterogénea son distinguibles a simple vista y su distribución no es uniforme.

Answer:
The correct option is: a. amniotic fluid released when the amniochorionic membrane ruptures
Explanation:
Amniotic sac is a sac that protects the fetus in the womb and contains the amniotic fluid. Amniorrhexis is the rupture of the amniochorionic membrane of the amniotic sac and the release of the amniotic fluid. The term water breakage is used to describe the rupture of the amniotic sac, generally at the onset of labor and the release of the amniotic fluid.
