The increase in the high fiber diet reduces the risk of colon cancer is suggested by the researchers. The effect of high fiber dietary intake add bulk to the digestive system. It also reduces the time required by the food to travel from the colon. Our food often contains some carcinogenic contents, so the interaction of such carcinogens may also be reduced due to the high fiber diet and also reduces the risk of intestinal tract. The bacteria in the lower intestine breaks the fibers into butyrate, which inhibits the growth of tumors of the colon and rectum.
Ciliates move (c) using cilia. It is a group of protozoans. Cilia is an organelle of ciliates. It is a hair-like organelle that helps the ciliate move. It is also used in many ways like food gathering. It could even be used to sweep down food to their central channel.
A have the MC1R gene and melanin deference
Ozone is formed by the reaction of of nitrous oxides and reactive organic substance catalyzed by sunlight. This is a photochemical reaction provided with ozone forming compounds and sunlight.
Acid rain is defined as nitrous(NO2) and sulfurous (SO2) compounds enter the atmosphere as smog thereby precipitating as acid rain. This is detrimental in the environment as well as in agriculture.
Global warming is precipitated by the burning of fossil fuels that increases carbon dioxide, a greenhouse gas that traps heat, in the atmosphere. The greenhouse effect is the main principle behind global warming.
Ocean acidification is when excessive carbon dioxide is dissolved in the oceans as carbonic acid thereby increasing the pH of the ocean. Increases in the pH of the ocean can affect the living conditions as well as industrial conditions near it.
Groundwater pollution is defined as contaminating the groundwater with the runoff from industrial agriculture including organic and inorganic wastes as well as infectious and nuclear wastes.
Algae blooms or algal blooms are precipitated by eutrophication or the increase in nutrients in water such as nitrogenous compounds and phosphorus from fertilizers. Eutrophication of water precipitates the abnormally high growth rate of algae.
Ozone layer destruction is associated with CFCs such as Freon and aerosols as these compounds neutralize and destroy ozone. These compounds form free radicals that convert ozone (O3) to oxygen (O2) thereby reducing its capability to protect the earth from UV radiation.
Deforestation is primarily caused by urbanization (cutting down trees to provide empty land in building structures) and industrial farming (converting forests into agricultural lands for farming).
