but the definition of beauty which you have accepted that triggers the attraction is almost entirely socially created, and it is changing every day. To prove this, just look at photos of “attractive” people from your parents’ generation and take note of your reaction to them. Just a sing...
Asthma, familial Mediterranean fever and Crohn's disease(inflammatory bowel disease) all result from an over-reaction of the immune system, while autoimmune polyglandular syndrome and some facets of diabetes are due to the immune system attacking 'self' cells and molecules. At what age does your ...
What is the reaction called where bonds are broken in a molecule by the addition of water and bigger molecules breakdown into their subunits? What is the term for a giant molecule formed by the joining of smaller molecules, usually by a condensation reaction...
Some of these methods are more efficient than others, and, over time, methods like reaction spinning, melt extrusion, and solution wet spinning have mostly been discarded. Nearly 95 percent of the world's spandex is now made with a method called solution dry spinning, and it is this ...
The aggregation disrupts normal brain cell function, eventually causing neurons to die. However, researchers don't know how repetitive head trauma might trigger tau buildup in the first place. Some studies hint that viruses in the brain may play some part in the chain reaction. CTE is ...

There are cases where it strikes quickly but it is more common when cancerous tumors manifest after years of specific habits. Good examples of this are smoking, exposure to radiation (i.e. from cell phones), and overexposure to ultraviolet rays, which result in lung cancer, brain cancer, an...
molecules. Although the pathway of hapten-specific T-cell activation is now well established, several questions need to be addressed: first, what is the nature of the hapten-modified peptides displayed by MHC? Second, how many of these peptides stimulate T-cells?; third, what are the ...
giant structures it takes a lot of energy to break all the bonds. as a result, ionic compounds have high melting points and boiling points . ionic compound examples for example, the reaction between magnesium and chlorine. the magnesium atom has two electrons in its outermost shell. by losing...
Its a part of ATP (Adenosine triphosphate), you know, the compound that fuels every cell in your entire body? Trisodium phosphate is just the salt form of the compound. Mixed with water, it just breaks back down into sodium (table salt) and phosphate! So many people scared of natural ...
