The main difference between suede and other types of leather is that suede fabric is derived from the underside of animal skin while most types of leather are derived from the top side of animal skin. The underside of animal skin is much softer than the outside, but it is also less ...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
However, it has been found that cancer can be promoted by large doses of some compounds that are chemopreventive when consumed in foods. One famous example is beta-carotene, which helps to prevent lung cancer when consumed in the diet but promotes lung cancer when take in high doses as a...
There are three essential elements involved in producing fire: heat, oxygen and fuel. To put a fire out, you need to effectively remove one of these elements. The best way to remove heat is to dump water on the fire. This cools the fuel to below the ignition point, interrupting the com...
Bioassays are important in the development of pharmaceuticals and lab testing. Bioassays help determine which compounds prove to be an effective treatment.10 What Is an Assay Value? An assay value is the quantity of an ore's valuable elements, calculated by multiplying its assay grade or percentag...
Up to5 percentof pharmaceutical elements are not removed by wastewater treatment and have been found in drinking water reservoirs. There have not been sufficient studies on associated risks of drugs in drinking water, though theEnvironmental Protection Agencyis working to determine pharmaceutical concentra...
