Body has got immune system. This immune system or the body immunity forms the antibodies to fight the viruses. The immunity against the viruses is usually life long.
the quantity of precipitate, which forms after the reagent antibody (precipitin) has incubated with the sample and reacted with its respective antigen to form an insoluble aggregate.
AIDS, HIV, and Epstein-Barr disease are all forms of auto-immune disease. There are others.
Naturally acquired immunity occurs through contact with a disease causing agent, when the contact was not deliberate, whereas artificially acquired immunity develops only through deliberate actions such as vaccination. they are both immunitys
Each antibody has a variable region at the top of the arms of the Y-Shaped structure of the antibody. These variable regions each have a different sequence of amino acids and therefore a different structure. This means that only specific antigens can bind to the binding sites - only those with a complementary shape. The antigen fits into the binding site by induced fit. Once the antigen has bound to the antibody it forms a highly specific antigen-antibody complex. Therefore the role of the variable region is to produce a specific binding site for each type of antigen.
Immunoglobulin A (IgA) is the primary antibody found in blood and respiratory secretions. It plays a crucial role in mucosal immunity, providing a first line of defense against pathogens in mucosal areas such as the respiratory tract. IgA exists in two forms: serum IgA, found in the bloodstream, and secretory IgA, which is present in mucosal secretions like saliva, tears, and respiratory fluids.
Active immunity is long term protection that generally lasts 20-30 years and passive immunity is immediate protection. there are two forms, naturally acquired and artificially acquired. in active immunity the naturally acquired immunity is when you suffer from the disease then recover again. the artificially acquired way is by getting a vaccination. in passive immunity, the naturally acquired way is to receive antibodies from mother in pregnancy and breastfeeding, the artificial way is to have antibodies injected in a serum for immediate response for example when you have been bitten by a poisonous animal. note they are not vaccinated.
Kinda. Its considered late.
Humans can develop active immunity naturally through exposure to a pathogen, which triggers an immune response and the production of antibodies. Artificially, active immunity can be induced through vaccination by administering weakened or inactivated forms of a pathogen, prompting the immune system to produce memory cells for future protection against that specific pathogen.
Endocytosis and exocytosis are forms of transport that are considered active, as they require energy to move substances into and out of the cell.
