The answer to your question is A.
Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.
Explanation:
When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.
As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.
Thanks to its memory cells, the virus will remain much less time in the body.
<h2>Cell Analogy</h2>
Explanation:
As we see that parents control everything in the house. Similarly,the nucleus controls everything in the cell.
A door is analogous to the cell membrane because it allows people come and go. Similarly,the cell membrane in a cell can allow certain things to enter and exit.
The cytoplasm fills the space in a cell. It is similar to air which is filled everywhere in the house.
- Nuclear membrane: Security guard
The nucleus in a cell is protected by nuclear membrane. The nuclear membrane is analogous to secuity guard. As people in a house are protected by security guard, similarly nucleus is protected by nuclear membrane.
- Endoplasmic reticulum: Hall ways
Endoplasmic reticulum transport things to other places in the cell. It is similar to hallways which help us to reach different places in the house.
The golgi bodies modify,sort and package proteins.
It send them to other parts of the cell when needed.
It is similar to a Car which transports people and can store stuffs.
The mitochondria in a house is analogous to Stove as it breaks down nutrients and turns them into energy. Similarly, the Stove in our house, cooks foods and it is converted into energy when consumed.
The ribosomes are a cell structure that make protein. It is same as a kitchen in our house where people make food or proteins.
The correct answer is -
E. double coincidence of wants
