Answer:

Epitopes.

Explanation:

Antigen: Antigens are foreign proteins that enter the host body through an infection. Antigens are generally high molecular weight proteins or polysaccharides. Viruses and bacteria contain antigen on their surface or inside the body.

Epitope: Epitope is the molecular region on the surface of the antigen which interacts with the antibody binding site on the antigen. Epitopes are capable of stimulating an immune response so, these are also known as antigenic determinants. Binding between the receptor and epitopes occurs when they both fit together like a puzzle, that event is necessary to activate B-cell production of antibodies.

URGENT! What results would you expect to see if exercise does not increase bone mass?
Nikitich [7]

When exercise does not increase bone mass, it has been observed that the risk of bone fractures increases due to osteoporosis.

<h3>What are the benefits of exercise to bone mass and density?</h3>

Bone mass refers to the mass of the bones in a living organism as a result of the deposition of minerals within the bone.

An increase in bone mass is directly related to the strength of the bone.

Strong bones have high bone masses whereas weak bone have low bone mass.

Physical activity have been shown to improve bone mass by increase the mass of deposited minerals in the bone.

Exercise such as walking, running, jogging, and other forms of exercise have been shown to improve bone mass and hence, the strength of bones.

However, when exercise does not increase bone mass, osteoporosis is observed which results in bone fracture.

In conclusion, the strength of a bone is directly related to the bone mass which is directly related to the mass of minerals deposited within them.
