Abundance of the chemical elements

Water is the key element to support the life and preserves natural ecosystems on earth. In the history of civilization water plays an important role for the establishment of habitat and also for expansion of trade. Most of the towns and cities were developed near sources of drinking water and along rivers for transportation.

agent “known to be carcinogenic” (CDC, 2014). The mechanisms by which formaldehyde produces its carcinogenic affects and the mechanism by which the cell repairs these aberrations inflicted on DNA is not know. This paper will focus on formaldehyde’s abundance in the surrounding environment, as well as the ways formaldehyde interacts with DNA to induce DNA damage. This paper will also briefly talk about some plausible mechanisms of DNA repair the cell…

Imagine this situation: Jennifer walks into a supermarket, and she goes through the aisles, buying a majority of healthy fruits, veggies, and lean meats. She undergoes this same shopping trip every week, believing eating a diet replete with healthy fruits, veggies, and proteins will lead to a long, healthy life. However, fifty years from now, Jennifer finds out she has cancer. How could this happen? Jennifer never acknowledged the difference between genetically modified and non-genetically…

Title Introduction Hearing the word magnesium might take you back to lab class in high school. You probably remember when we mixed various chemicals and someone would invariably cause an explosion. It seems like magnesium was involved in some way. That was exciting; however, if you’re reading this, that’s probably not the Magnesium in which you’re interested. If it is, then you’re in the wrong place so head back to Google. The magnesium you’re perhaps looking for is the one that’s located in…

Introduction Mammalian Skin: The Basics The first line of defence between the outside world and inside an animal is the skin. It is an effective barrier against physical, chemical and pathogenic assault (1). However, the skin is not only a barrier but a sensory organ enabling animals to sense the surrounding environment, provoking appropriate responses for animal survival. There are two main types of skin; thin skin (hairy), which makes up nearly all the skin on the body, and glabrous skin…

population growth, use of chemical fertilizers and pesticides has been increased in agriculture. Many agricultural practices have harmful effects on soil quality and contribute to both surface soil and ground soil pollution. Because of low efficiency, fertilizers get accumulated in soil over time and cause ill effect on soil fertility and productivity. Chemicals or salts present in pesticides have also harmful effect on plants and animals when left behind in the soils. These chemicals along with…

What the stream team will be doing is going to the stream and seeing how much nitrate, phosphates, dissolved oxygen, turbidity, temperature, and pH is in the water. The stream team will look at the effect on water quality, the effect on plants and animals, the acceptable levels for swimming, sources and sources categorized, the best management practices, whether the sources are point source, or nonpoint source pollutants, and the test results. The stream team will be doing all of those topics…
