Answer:
A. it does not change
Explanation:
the temperature of water does not change if you heat it after it has already reached the boiling point
after boiling point the temperature becomes constant and the heat energy supplied is used for vaporization .
<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>
Atherosclerosis
Explanation:
Correct order of the sequence of events that leads to atherosclerosis is:
c, d, b, a
Development of atherosclerosis is caused by a high concentration of LDL‐cholesterol in the blood, and lowering the level of LDL‐cholesterol reverses atherosclerosis thus preventing cardiovascular disease
Cholesterol is the key component of arterial plaques which gave rise to the cholesterol hypothesis for the pathogenesis of atherosclerosis
Population studies have shown that elevated levels of both LDL cholesterol and apolipoprotein B (apoB) 100, which is the main structural protein of LDL, are directly associated with risk for atherosclerotic cardiovascular events
Answer:
a. significantly lesser
Explanation:
The density of protists living in the hay infusion is significantly lesser than the regular pond water because protists likes to live in aquatic or any water bodies. Some protists float on the surface of the water making their own food like plants by using the process of photosynthesis. Aquatic environments are ideal environment for protists, which have cilia and flagella that allows them to move in the water in search of food..
