Exploring the former lakes of Mars, these scientists are hoping to answer one of the major questions of astronomy and biology. Is life a pretty ordinary phenomenon in the universe, popping up wherever conditions are favourable, or is it really a one-off phenomenon that we have practically no ...
Aminotelism (Type of excretion – amino acids) Guanotelism (Type of excretion – guanine) What is excretion and types? Humans must get rid of two types of wastes. Wastes from the digestive system (feces) and wastes from metabolic activities (sweat & urine). Removing digestive wastes (poopin...
There are two major classes of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the molecule that contains all of the information required to build and maintain the cell; RNA has several roles associated with expression of the information stored in DNA. Of course,...
Biology is the study of life. The word "biology" is derived from the Greek words "bios" (meaning life) and "logos" (meaning "study"). In general, biologists study the structure, function, growth, origin,evolutionand distribution of living organisms. Biology is important because it helps us...

Watson, Crick and Wilkins were awarded theNobel Prize in medicinein 1962 "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material." Franklin was not included in the award, even though her work was integral to the re...
And so this is what we're doing in my lab. We're developing new medicines that are basically cell-surface lawnmowers -- molecules that go down to the surface of these cancer cells and just cut off those sialic acids, so that the immune syste...

produce negative OH-ions and positive ions. Acids on the other hand, produced positive H+ions and other negative ions. This theory works well for many common chemicals such as lye or NaOH. Lye dissolves in water to form positive sodium Na+ions and negative OH-ions, and it is a strong ...
