Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of immunity is the cell attack?
A
direct
B
indirect
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The adaptive immune system takes over if the innate immune system is not able to destroy the germs. It specifically targets the type of germ that is causing the infection.

Detailed explanation-2: -There are B and T type lymphocytes. B lymphocytes become cells that produce antibodies. 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.

Detailed explanation-3: -The innate immune responses are the first line of defense against invading pathogens. They are also required to initiate specific adaptive immune responses. Innate immune responses rely on the body’s ability to recognize conserved features of pathogens that are not present in the uninfected host.

Detailed explanation-4: -Killer T cells are called “cytotoxic” or “cytolytic” because they possess special molecular weapons that enable them to directly attack and destroy other cells displaying targets they recognize, for example, a virus-infected cell or even a cancerous cell.
