is important that antibodies have a symmetrical quaternary structure to create
two identical binding sites for antigens. An antibody is a relatively large
protein having a Y-shape. Plasma cells produce antibodies which are then used
by the immune system to fight off pathogens (e.g. bacteria and virus). The antibody
is able to recognize the antigen of the pathogen. It binds with it either to
neutralize it directly or “tag” the microbe for future attack by other parts of
the immune system. </span>

Hail is formed when the water droplets freeze together in the cold upper region of the thundercloud. These lumps of ice are called hailstones. Most hailstones are between 5 mm and 15 cm in diameter and can be round or jagged. Hail stones are not frozen raindrops.
Factors that govern the ultimate size of hailstones are hail has strong storm clouds, especially strong heat, high liquid water content, large vertical range, large water droplets, and many cloud layers are formed by clouds below 0 ° C (32 ° F). This type of intense heat may also indicate the presence of a tornado.
