A frame shift mutation is a genetic mutation caused by insertions or deletions of nucleotide in a DNA sequence that is not divisible by 3.
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.
Answer:
The effort put by scientist and sailors about earth is that they keep on going round the earth and putting their lives in danger and some even give their lives.
Explanation:
......
Archaea and Bacteria were grouped together because they were both Prokaryotes since they had no nucleus. Scientists then realized they were different because archaea can live in extreme environments, and bacteria can't.
hopefully my answer helps u
Cellular respiration associates oxygen with glucose within the mitochondria to generate ATP; water and carbon dioxide are generated as well. Photosynthesis utilizes energy from sunlight to produce glucose and distinct oxygen from carbon dioxide and water.
The cellular respiration uses the outcomes of photosynthesis and photosynthesis utilizes the outcomes of cellular respiration at its initial stage.
Both the process of cellular respiration and photosynthesis exhibit an equal enthalpy. Thus, the correct answer is option A.
