Answer: Keeping those genes locally in the mitochondria gives the cell a way to individually control mitochondria,” Johnston says, because pivotal proteins are created in the mitochondria themselves. ... Other structures in our cells could also benefit from this type of local control.
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:
Explain how heat in the atmosphere and water affect weather?
Amount of water in the atmosphere determines the amount of rainfall which depicts how cool the environment would look like.
Water has a great effect on the weather as evaporation helps to determine whether there would be heat or not, when there is high rise of evaporation it shows that the environment or weather is hot vice versa
