Acid-base homeostasis - Acid-base homeostasis is the part of human homeostasis concerning the proper balance between acids and bases, in other words the pH. The body is very sensitive to its pH level. Outside the range of pH that is compatible with life, proteins are denatured and digested, enzymes lose their ability..

Pollen Proves Beneficial For Northern Lakes - ScienceDaily (June 12, 2006) — Mention the word pollen to most people and it triggers thoughts of their battle against allergic reactions. However, a University of Alberta researcher has found an important spin-off for this fine yellow dust-like powder. See also: Plants & Animals Ecology Research Marine Biology Agriculture and Food Nature Sea Life Biology Reference Fertilisation Characteristics of common wasps and bees Phytoplankton Plant sexuality Mark Graham, a PhD student from the Department of Biological Sciences at the U of A, has shown for the first time the benefits of pollen on boreal lakes. Rich in nutrients, pollen is an essential component of plant fertilization but few think of its importance to fertilize lakes. Wind-dispersed pollen in early summer is not only visually striking, but it can represent a substantial pulse of nutrients to northern lakes. Graham's research team found that plankton responded strongly to additions of pollen in experimental enclosures, located a....

Enzyme Important In Aging Identified - ScienceDaily (July 13, 2009) — The secret to longevity may lie in an enzyme with the ability to promote a robust immune system into old age by maintaining the function of the thymus throughout life, according to researchers studying an 'anti-aging' mouse model that lives longer than a typical mouse.

In all mammals, the thymus―the organ that produces T cells to fight disease and infection―degenerates with age. Results of the study are published in the July 7 issue of the Proceedings of the N....

Scientist Discovers Novel Iron-copper Alliance - ScienceDaily (July 30, 2007) — Iron is the workhorse of trace minerals. An essential component of red blood cells, disruption of iron levels in the body will result in a myriad of serious conditions, and life cannot be sustained without it. See also: Health & Medicine Dietary Supplement Vitamin Alzheimer's Research Matter & Energy Biochemistry Batteries Sports Science Reference Micronutrient Dietary mineral Essential nutrient Heavy metals In novel research, investigators at the University at Buffalo's School of Public Health and Health Professions, have learned that iron is only one half of an all-important duo of trace minerals -- the other being copper -- that work in tandem to maintain proper iron balance, or homeostasis. It appears the workhorse has a helper. James F. Collins, Ph.D., UB assistant professor of exercise and nutrition sciences and biochemistry, discovered that when iron-absorption by cells lining the small intestine decreases during iron-deficient states, copper abs....

Bugs Expose Underground Carbon Traffic System 10 Times More Important .. - ScienceDaily (Oct. 8, 2005) — The flow of carbon through soil is ten times greater than the amount of carbon moved around by the burning of fossil fuel but until now how this happens was at best poorly understood. Soil was almost literally a black box to scientists interested in carbon. Now researchers at the University of Warwick have been able to shed light in that black box by getting a particular class of insects to expose the key underground carbon traffic system - by eating it.

  The Power of Hydrogen   For our video, we explored ph. We made the theme of our video superhero and comic book-like because ph stands for the the power of hydrogen. Our mission was to show examples of ph in our environment as well as demonstrate how it is related to the processes of homeostasis and denaturization. Before doing this assignment, we never really associated ph as being something important to the function of cells. We discovered it is an important part of homeostasis, which is a balance all organisms must maintain in order to functions. Homeostasis could be a balance between cell membranes and a solution or between organs and many other examples. Maintaining ph levels is a part of a cells ability to achieve homeostasis. We knew homeostasis was a crucial part of life but we did not realize how important ph was to it! Additionally, we explored phs relationship with enzymes, particularly their role in denaturization. First, we had to explain to the audience the meaning of the lock and key theory. The..

Question : Importance of separation technique used in chemistry in day to day life.

Answer : any material made up of two or more substances that are not chemically combined . Each component in a mixture retains its own set of physical properties. the isolation of pure components of a mixture requires the separation of one component from another. separation of the components of mixture is performed through routine process of chemistry.

Question : Question 1 Which of the following provide(s) evidence for the importance of water for biology? (p. 25) Liquid water is abundant in rain forests, where diverse life is abundant, and rare in deserts, which have much less life within them. About 2/3 of most organisms' masses consist of water. Many molecules can move around and interact easily in an aqueous environment. All of the above are evidence for water's importance. Only two of the above provide such eviden..

Answer : 1.) All of the above are evidence for water's importance. 2.) True 3.) There is an equivalence between the concentrations of H+ and OH- within it. 4.) Adhesion to the walls of the tube cause the top surface to advance upward, and cohesion between the individual water molecules pull along the molecules beneath. 5.) As it freezes, its density decreases. 6.) It absorbs or releases H+ ions reversibly to resist a pH change within its buffering range.

Question : Why does the blood contain pH buffers?

Answer : Blood has pH buffers to maintain a stable pH of our blood. Why do we need a stable pH? Enzymes and cells are sensitive to changes in pH. Enzymes and other proteins can have their shapes altered (aka denatured) when pH is changed & since the shape of an enzyme is so important to its function (because it's shape is what allows it to bind to a specific substrate). If enzymes can't function then processes in the body would not be completed thus leading ultimately to death.
