Active and passive immunity involves all of the following except receiving mother's antibodies through breast-feeding. exposure
Bingel [31]

Explanation:

Immunity is the ability of an animal to resist infection.

There are two types of immunity in the body; INNATE OR INHERITED IMMUNITY AND ACQUIRED IMMUNITY. Inherited immunity it is the type of immunity that one is born with. It is passed from parent to offspring.

Acquired immunity is immunity to particular infections that is not inherited but has developed in the animal's life as it interacts with its environment. Acquired immunity can develop naturally in which case it is called NATURAL ACQUIRED IMMUNITY OR ARTIFICALLY.  

ACTIVE IMMUNITY is the form of acquired immunity in which the body produces its OWN antibodies against infections. While PASSIVE IMMUNITY is the form of acquired immunity in which an individual is PROTECTED AGAINST INFECTION BY RECEIVING ANTIBODIES.  

NATURAL ACQUIRED IMMUNITY

when attacked by the same pathogens again, they don't became seriously ill. this is because memory cells are able to recognise the antigens and stimulate the immune system to produce antibodies against the pathogens. This is known as NATURAL ACTIVE ACQUIRED IMMUNITY. It develops when one recovers from an infection.

During pregnancy, the mother passes antibodies across the placenta to the foetus. At birth the baby gets antibodies from the mother through breast milk. This is natural passive acquired immunity.

xxTIMURxx [149]

Answer:

Explanation:

The nervous system is divided into the central nervous system (CNS) & peripheral nervous system (PNS). The brain and the spinal cord comprise the central nervous system. The peripheral nervous system serves the rest of the body and they branch from the spinal cord. Ii is in the peripheral nervous system that you'll find motor and sensory neurons. The sensory neurons take information to the CNS to be processed. After processing information, the CNS sends back information through the motor neuron of the PNS indicating which action to be taken based on the ‘input’ information.
