Antibodies have a variable region that binds to a specific antigenic determinant.
Antibody
An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system or can neutralize it directly (for example, by blocking a part of a virus that is essential for its invasion).

Answer:
Explanation:
Science (genetics, molecular biology, genomics) genes or gene products that are homologous (descended from a common ancestor) and are found in separate species due only to the speciation event (not to gene duplication).

Atlantic Cod is a marine fish. The fish has less salt in its internal body while the salt concentration in the sea water in which the Cod lives is high. Thus through the process of osmosis ( a process in which an element moves across a permeable membrane from regions of high concentration to the regions of low concentration) the salt moves from the ocean into the fish body. In such scenario the metabolism of the fish body gets disturbed, and there is an urgent need to remove the excess salt with the help of Kidney (through extremely concentrated urine) by going against the concentration gradient in order to maintain the homeostasis.
Jb Kown, the anthropologist in question, compares the fieldwork settings by their <u>fight for equality.</u>
Such is the case in many countries around the world, South Korea at times struggles to maintain equality in all of its settings, such as in factories. Anthropologist jb Kwon researched factory workers and found that <u>inequality </u>is present in the form of job and wage distribution between men and women.
The anthropologist Jb Kwon compares this with the anti-racist work he took part in after the Micheal Brown incident in that they are both done to argue <u>for </u><u>equality </u><u>among all people</u>, regardless of <u>gender</u>, <u>race</u>, or <u>background</u>.
