Another difference between antigen and antibody is where they are. Antigens are “hooks” on the surface of cells and are found in nearly every cell. You can find IgA antibodies in the vagina, eyes, ears, digestive tract, breathing passages, and nose, as well as in blood, tears, and saliva.
Temperature affects the type of plants because different plants require different temperatures and precipitation levels. Such as in the case of cacti, they need very little precipitation and can withstand very high levels of heat.
