Explanation:
There are several types of antibodies and antigens, and each antibody is capable of binding only to a specific antigen. ... Antigens are bound to antibodies through weak and noncovalent interactions such as electrostatic interactions, hydrogen bonds, Van der Waals forces, and hydrophobic interactions.
Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
<span>The epidermis is mainly a composition of cells called keratinocytes. Defensive cells are known as Langerhans cells and are one of the three types of specialized epidermal cells, The epidermis is bonded to the dermis. Hairs grow in the dermis and up to the epidermis. So, the dermis and the epidermis both have cells and hair. </span>
