A person acquires active immunity when their own immune system produces antibodies in response to the presence of a pathogen. Active immunity can result from either getting the disease or being vaccinated.

Active immunity can be acquired through natural exposure to an infectious agent, which triggers the body's immune response to produce antibodies. It can also be acquired through vaccination, where the immune system is exposed to a weakened or inactivated form of the pathogen, leading to the production of antibodies without causing illness.
Both active and passive immunity provide protection against specific pathogens. Active immunity is developed by the body after exposure to a pathogen or through vaccination, while passive immunity is acquired through the transfer of pre-formed antibodies from another source. Both types of immunity are specific to the pathogen encountered or targeted by the antibodies.
Natural immunity is acquired through natural exposure to an infectious agent, or through maternal antibodies passed from mother to child. Artificial immunity is acquired through vaccines or deliberate exposure to an infectious agent, without experiencing the full illness. Both types of immunity result in the body producing antibodies to protect against future infections.
passive transport and active transport.
Cells use the energy from ATP for active transport and cell division.
Immunity is the body's ability to resist or fight off infections or diseases. It is achieved through a complex system involving various cells, tissues, and organs that work together to protect the body from harmful pathogens. Immunity can be acquired naturally through exposure to diseases or artificially through vaccines.
