They bind to MHC class I molecules and T-cell receptors
Following influenza infection or receipt of a flu vaccine, the body's immune system develops antibodies that recognize and bind to “antigenic sites,” which are regions found on an influenza virus' surface proteins
<h3>What are Antibodies ?</h3>
When the immune system of the body recognises dangerous compounds, known as antigens, it produces a protein called an antibody. Microorganisms (bacteria, fungi, parasites, and viruses) and chemicals are examples of antigens.
- Proteins called antibodies defend you when your body comes into contact with an unwelcome chemical. Antibodies, which are made by your immune system, bind to these foreign chemicals and drive them out of your body. Antibody is also known as immunoglobulin.

For this item, we assume that the gas behaves ideally such that it follows the ideal gas law and the ideal gas equation is applicable.
PV = nRT
where P is pressure, V is volume, n is number of moles, R is universal gas constant, and T is temperature. When the right-hand side of the equation is constant, there exist a relationship that,
P₁V₁ = P₂V₂
Substituting the given,
(0.410 atm)(32 L) = (P₂)(28 L)
The value of P₂ is equal to 0.4686 atm.
All of these models apply to the scenario equally well.
Explanation:
- Firstly, the male crabs battle each other for territory using their greatly enlarged claws. This clearly depicts male-male competition.
- Secondly, Females choose to mate with only those male who are fit to survive in stress full condition. Thus female look for good genes that would enable her offspring to survive in stressful condition. Here Good gene mechanism applies.
- Thirdly, The presence of large claws make it more noticiable to female and stronger to compete with other males. Thus this is a direct benefit.
- Lastly, we see that female crab have a tendency to look up for their prey and this tendency is well exploited by male crabs who raise their claws to a heigh so that they get noticed by the female.
