They bind to MHC class I molecules and T-cell receptors
Following influenza infection or receipt of a flu vaccine, the body's immune system develops antibodies that recognize and bind to “antigenic sites,” which are regions found on an influenza virus' surface proteins
<h3>What are Antibodies ?</h3>
When the immune system of the body recognises dangerous compounds, known as antigens, it produces a protein called an antibody. Microorganisms (bacteria, fungi, parasites, and viruses) and chemicals are examples of antigens.
- Proteins called antibodies defend you when your body comes into contact with an unwelcome chemical. Antibodies, which are made by your immune system, bind to these foreign chemicals and drive them out of your body. Antibody is also known as immunoglobulin.

Answer:
Pelagibacter ubique is often cited as the most common organism ever: it's a third of all the single-celled organisms in the ocean. But, as is always the case, something eats P. unique. In fact, four different viruses parasitize this one species.
Explanation:
Bacteria are monerans, the simplest single-celled organisms. They are the smallest of all cells, visible only through powerful microscopes. Bacteria are also the most abundant forms of life. ... Bacteria recycle nutrients in the soil and aid the human digestive system.
The following model health claims can be used in the food labeling to illustrate the association between vitamin D, calcium, and osteoporosis:
1. Sufficient vitamin D and calcium throughout life, as a component of a well-balanced diet, may minimize the threat of osteoporosis.
2. Sufficient calcium and vitamin D as a component of a healthful diet, alongside physical activity, may minimize the threat of osteoporosis in the later stages. Thus, the given statement is True.
The response is known as hydrotropism.
