Answer:
The correct order would be:
A vaccine introduces a weakened flu virus into the body.
↓
The immune system identifies antigens on the weakened flu virus.
↓
Antibodies are produced, which bind to the weakened flu virus and signal immune cells to destroy it.
↓
The actual flu virus enters the body, and lymphocytes recognize the antigens.
↓
Antibodies are quickly produced and allow the body to fight off the infection.
Vaccination or immunization is the process which helps in developing the immunity (adaptive) against a particular pathogen or microorganism.
It includes the administration of antigen, weakened or heat-killed microorganism (such as flu virus) into the patients body. Body's immune system produces naive B and T cells to eliminate the antigen.
This encounter enables the immune system to produce memory B and T cells against that particular pathogen.
In future, whenever the same antigen enters the body, the immune system gets activated quickly due to the presence of memory cells. It enables the body to produce more effective secondary response against the pathogen.
Photosynthesis is just a fancy word that describes how plants make their own food. photo means 'light' and synthesis means 'to put together'.
The three things that the plant "puts together" are sunlight, carbon dioxide, and water. When a plant receives these 3 things, something happens; an organelle in the cells of the plant called chloroplasts combine them and turn it into sugar in which the plant eats. Cool, huh?

There are many ways in which they are different but one of the important one is :
in photosynthesis, CO2 is used and O2 is released while in cellular respiration O2 is taken and CO2 is released !
Answer:
Attraction: is a feature of some sort that draws two things together. For example, opposite sides of magnets <em>attract</em> each other,
Repulsion: is the opposite of attraction. Instead of bringing things together, it pushes them apart.
Explanation:
Atomization refers to separating something into fine particles.
