The invention relates to compounds of the structure of formula I and II: where X is selected from the group consisting of O, S, and NH;Y, A and B are independently selected from the group consisting of N and CH; D, E and F are independently selected from the group consisting of CH...
In this upper atmosphere, ozone is made when ultraviolet light from the sun splits an oxygen molecule (O2), forming two single oxygen atoms. If a freed atom collides with an oxogen molecule, it becomes ozone. Stratospheric ozone has been called "good" ozone because it protects the Earth's...
Such biochemical arrangements almost always rely on feedback loops—and the crucial molecule in the loop that matches cell physiology to oxygen availability is a protein complex called hypoxia-inducible factor (HIF). HIF was discovered and named by Dr Semenza, who works at Johns Hopkins University...
An RBC contains hemoglobin, a molecule specially designed to hold oxygen and carry it to cells that need it. The primary function of red blood cells is to transport oxygen from the lungs to the cells of the body. RBCs contain a protein called hemoglobin that actually carries the oxygen. In...
There is a very ___ dipole-induced dipole attraction between an oxygen molecule (O2) and water (H2O). Hydrofluoric acid Glass is very soluble in what solution? Acetone Styrofoam is not soluble in water, but is in ___. False, sucrose solubility increases with increasing water temperature....
through the catalyst, where it forms two oxygen atoms. Each of these atoms has a strong negative charge. This negative charge attracts the two H+ ions through the membrane, where they combine with an oxygen atom and two of the electrons from the external circuit to form a water molecule (...
Contrary to popular belief, cockroaches cannot survive a nuclear explosion; however, it is true that cockroaches are more tolerant to certain ionizing radiation than humans. Even so, they cannot survive bug spray, as it consists of certain neurotoxic sub
