. If a person comes in contact with this same virus years later, what does our body produce to get rid of or kill the virus
borishaifa [10]

If a person comes in contact with this same virus years later, our body produces antibodies to get rid of or kill the virus

Explanation:

When a person is infected by a virus, the infected person's body develops antibodies as an immune response to act against the virus. Antibodies are produced as part of humoral immunity.

Antibodies work by neutralizing the viral activity, agglutination,  phagocytosis or by complement system.

Antibodies are protein compounds which can recognize the invading pathogens and attack them.

Antigens or viral proteins in the virus leads to the production of antibodies in the host's body.

The specific antibodies triggers innate immune response upon detecting specific viral antigens when infected and will help the body to get rid of  or kill the virus.

"Dietitians often recommend that we frequently consume foods containing omega-3 fatty acids. An omega-3 fatty acid is one that h
9966 [12]

An omega-3 fatty acid is one that has its first double bond at the <u>methyl </u>end of the molecule.

Explanation:

Fatty acids will have a methyl end and a carboxylic acid end and the long carbon chain.

The number of hydrogen atoms attached to the carbon atoms depends upon its saturation type – saturated or unsaturated fatty acid.

The main advantage of the unsaturated fatty acids is that they have fewer hydrogen atoms because they are replaced with a double bond between the carbon atoms.

There are both short chain (carbon atoms 18 or less) or long chain (more than 20) fatty acids.

Omega-3 fatty acids are polyunsaturated fatty acids (PUFA). Depending upon the carbon chain length, the first C=C double bond occurs between the third and fourth carbon atom from its methyl end on the carbon chain of the omega-3 fatty acid.

Omega-3 fatty acids are recommended by dieticians due to its immense health benefits especially for the heart since it reduces blood triglyceride level, blood pressure, plaque formation, and the risk factors for heart attacks or failure. These are also good for the eyes, to treat mental depression, and for fetal brain development during pregnancy.
