R136a1 and our Sun both are made of the same compounds and molecular build, however R136a1 is 261 times bigger and the mass is approx. 261 times greater than our Sun's mass.
<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>
D
Wave B because the compressions are more tightly packed, giving it a larger amplitude
A macrophage is a large phagocytic cell that engulfs foreign particles and pathogens. So Macrophage.
Hope this help! :)
<span>tRNA - Transfer RNA: Brings amino acids to ribosomes during translation.
rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
<span>snRNA - Small nuclear RNA: With proteins, forms complexes that are used in RNA processing in Eukaryotas. (Not found in prokaryotes.)</span></span>
