The sun and its rays can be just as harmful as it is beneficial. Sunlight is needed for Vitamin D and energy, but the sun also produces Ultraviolet-A (UVA) and Ultraviolet-B (UVB) rays that can harm the body. Even though the sun’s rays can do damage to the body, many Americans choose to tan. According to skincancer.org, nearly 30 million Americans choose to tan indoors with the use of tanning beds.

In fact, it is the most common form of crystal-induced arthropathy, and the most common inflammatory arthopathy in men older than 40 years (Bolognia, First Consult). Gout is a deposition disease of metabolic origin caused by supersaturation of monosodium urate, or hyperuricemia. Needle-like crystals are deposited into joints, connective tissue, and the kidneys.…

Scientists consider stem cell research and stem cell therapy as having a positive impact on treating different forms of cancer. While embryonic stem cell research is extremely controversial, stem cells used in cancer treatment such as leukemia are different. Unlike embryonic stem cells that use an embryo for regeneration of healthy cells, the cells used in leukemia treatment are called hematopoietic stem cells. The use of stem cell therapy has increased the survival rate of leukemia patients…

Qn1 Ans Decision tree analysis will involve step determination of the chemical and physical characteristics of this chemical. By knowing them, it will be very easy to determine the best control method to be employed. Firstly, the compound is corrosive and it therefore suggests that it is highly reactive and use of water and any other chemicals that can lead to an undesired chemical reaction will be ruled out. Also, the spilled chemical is producing fumes, mostly it suggests that it is either a…

Although animal experimentation has provided many benefits, there are alternatives to test toxic substances that may eliminate the cruel use of animals in research. The United States, along with many other countries, have turned to the use of animals in research labs to test human products for hazardous substances. According to the Kennedy Institute of Ethics Journal, the United States uses about 12 million animals every year making it the biggest conductor of animal experimentation in the world…

1. A perception is when sensory impulses are interpreted in the brain, such as touching a hot stove. A sensation is when the brain becomes aware of a stimulus, such as pain. 2. Pain receptors are excited by any type of tissue damage. 3. Referred pain is a phenomenon when you feel pain in an area other than where the pain originates from. 4. The thalamus and cerebral cortex are the parts on the brain that interpret pain impulses. The thalamus establishes the awareness of pain, and the…
