Order the steps for vaccination. pathogens enter the body and the body can remember the pathogen using memory cells, destroying the pathogen. a weakened or dead form of the pathogen is injected into the body. white blood cells produce antibodies that destroy the pathogen. the pathogen is not strong enough to cause disease but its presence in the body signals the body to protect itself against the pathogen.

A vaccine is known to be the biological preparation that are known to provide acquired active immunity to a body against a particular disease. It consists of agents that is similar to disease causing microorganism, it is often made up of weakened, killed form of microbes or its toxin or its surface protein.

Vaccination is the treatment which makes body stronger against a particular disease. It helps body to fight against infection by making antibodies against pathogen.

The steps of vaccination are:

 A weakened or dead form of the pathogen is injected into the body

                                                             ↓                                                    

The pathogen is not strong enough to cause disease but its presence in the body signals the body to protect itself against the pathogen

                                                              ↓

White blood cells produce antibodies that destroy the pathogen

                                                               ↓

Pathogens enter the body and the body can remember the pathogen using memory cells, destroying the pathogen

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2
