Ultraviolet radiation may increase when there is an increase in sunspots
A) heat is related to speed/ energy of molecules so when it is decreased the molecules slow down and stop bouncing around/ loose energy
A temperature inversion occurs when a layer of warm air settles on top of a layer of cold air, and the cold air ends up trapped underneath.
CARBOHYDRATE HELPS TO IDENTIFY CELL TYPES.
Carbohydrates, proteins and lipids are all present inside the cell. Carbohydrates are usually attached to the cell proteins and lipids in order to enhance their functionality. These attached carbohydrates are typically used to identify cells.
<span>The most crucial principle of ELISA (enzyme-linked immunosorbent assay) is a highly specific antibody-antigen interaction.</span>
ELISA is a biochemical technique used to detect the presence of an antibody or an antigen in the biological sample. Simply described, in an ELISA, an antigen is immobilized on a solid surface and then a specific antibody is applied over the surface so that it can bind to the antigen. The antibody is usually linked to an enzyme, and in the final step, a substrate for that enzyme is added. The enzyme can convert it to some detectable signal, most commonly a color change. <span>Medical usage of ELISA is in the diagnosis of HIV infection, pregnancy tests, measurement of cytokines…</span>
