Explanation:
Correct answer:
A vaccine is a substance that stimulates the antibodies production and helps to provide immunity against one or more than one disease. It is made by taking a small amount of dead or whole weaned germs such as bacteria or virus that cause the disease.
When these weakened pathogens are introduced in the body they evoke the immune response inside the body and activates T- cells and B-cells inside the body, which prepare antibodies against that antigen in advance in order to save the body from infection by the same pathogen in the near future.
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
Answer:
The rise in the level of water indicates that CO2 is produced by germinating seeds during respiration. Actually, the germinating seeds respire and produce CO2.
It would be convection because it isnt having any physical collision which rules out conduction and it is going through mid air which rules out evaporation and radiation
