Vitamin D is produced in the skin in response to ultraviolet light exposure however dancers spend long periods of time indoors so have limited exposure to sunlight, as a result they are often vitamin D deficient which can lead to injuries and underperforming. The importance of vitamin D should not be overlooked as ‘Vitamin D receptor sites have been identified in virtually every tissue within the body’. Vitamin D is important in aiding the absorption of calcium which improves bone strength,…

atoms—leading to conformational changes which cause base-pair bonds to be broken, shifted, or replaced, causing genetic mutations, or abnormalities in the typical phenotypic expression of an organism. The purpose of this lab was to understand more about ultraviolet light as an agent of mutagenesis and become familiar with the manipulation of the single-celled fungus Saccharomyces cerevisiae. Through a series of experiments, the effects of varying degrees of UV radiation exposure on cultures of…

Systemic Lupus Erythematosus also known as SLE is an autoimmune disease that attack’s its own tissues. Systemic Lupus Erythematosus is a chronic disease. Systemic Lupus Erythematosus is the most common form of Lupus with 200,000 new patients diagnosed each year in the United States with 1.5 Americans living with a lupus diagnosis and there are many cases that go undiagnosed. When it comes to common causes the cause of Systemic Lupus Erythematosus is unknown but scientists have come to believe…

Most of the traits that organisms inherit are not harmful (they are usually helpful or neutral). An example of this is blood type in humans which is passed onto new generation and is not an advantage or disadvantage, but neutral. There are two kinds of chromosomes that are present inside cells and that are passed on to offspring during sexual reproduction. These are autosomes and sex chromosomes mutations in each determine. Some traits however can be harmful. An example of this are diseases that…

Increasing roughness, mainly from sunlight that destroy the skin’s collagen and elastin, the skin cells start to turn over in an irregular fashion resulting in scaly patches of rough skin. 2. Spots everywhere due to Constant exposure to the sun’s ultraviolet rays makes our skin pigment act abnormally, resulting in spots throughout the face, upper chest, and hands—basically, anywhere the sun has shone on. 3. Excessive wrinkling, particularly on the cheeks, neck, and forehead, is usually seen only…

sun burns, skin cancer and plants damages are as a result of the UV rays that can no longer be absorbed by the ozone layer. Global warming has depleted the Ozone layers, and it’s not possible to shield human beings and plants from the harmful ultraviolet rays emitted by the sun. Carbon dioxide gases are emitted mainly from cars and factories. Currently, there are about 800 million vehicles that contribute the green house gases. This is mainly seen in the current warming of the globe such as…

Most fossils are found within layers of sedimentary rocks called strata. Deeper strata are usually older and therefore fossils from different time period can be compared. Analysis of fossils from different strata suggests that more complex, modern organisms evolved from simpler, more ancient organisms.Imprint fossils are one example of fossils that died and been buried and the sediments get preserved. Biogeography is the study of species distributions. It examines how species have been…

Do you know what are air pollution and its effects on human life and even the environment? Air pollution is one of the virtual problems nowadays and it can damage human life and the environment. Air pollution is the introduction of chemicals, biological materials or other harmful materials into the Earth atmosphere, possibly causing disease, damage to other living organisms such as the built environment and death to human. In addition, most people assume that air pollution is a common problem…

Importance of eating organic kales Overview Most of us have learned in health education that vegetables are the essential food substance for a one to be healthy and free from frequent diseases. Many are the times when the health experts advise us to include vegetables in every meal but because of ignorance, we continue with the normal unbalanced diet.
