The flu vaccine activates adaptive immunity. How does this occur? A vaccine introduces a weakened flu virus into the body. The i

mmune system identifies antigens on the weakened flu virus. Antibodies are quickly produced and allow the body to fight off the infection. The actual flu virus enters the body, and lymphocytes recognize the antigens. Antibodies are produced, which bind to the weakened flu virus and signal immune cells to destroy it. PUT IN ORDER

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.

Olin [163]

Answer:

Th acceptable distance of tubulin monomers along a protofilament is : <u>A. 4nm</u>

Explanation:

MICROTUBULES are an important component of the cytoskeleton of eukaryotic cells. Its function is part of a structural role that helps define cell morphology, and also serves as an intracellular motor for some proteins such as kinesin and dynein.  

For the correct formation of the structures called microtubules to occur, a process called polymerization is required. In this process there is a head-to-tail junction in which the dimer junction between tubulines forms a structure called protofilaments and those protofilaments run along the microtubule. Then, the other process occurs in which, by lateral interactions between the structures mentioned above , the wall of The microtubule will be completed.
