The answer to address both these problems is called biofortification. This area looks at improving food quality with respect to protein, oil, vitamin, micro nutrient and mineral content.

The answer to address both these problems is called biofortification. This area looks at improving food quality with respect to protein, oil, vitamin, micro nutrient and mineral content. The oils need to be rich in omega 3 fatty acids which are good for heart. Similarly, proteins should have more of lysine and tryptophan (essential amino acids). Many varieties of maize, carrots and spinach have been released which fulfill the above criteria.
Allergy is the exaggerated response of the immune system of certain antigens present in the environment. In metropolitan cities life style is responsible in lowering of immunity and sensitivity to allergens. More polluted environment increases the chances of allergy in children. Some symptoms of allRead more
Allergy is the exaggerated response of the immune system of certain antigens present in the environment. In metropolitan cities life style is responsible in lowering of immunity and sensitivity to allergens. More polluted environment increases the chances of allergy in children. Some symptoms of allergic reactions are sneezing, watery eyes, running nose and difficulty in breathing.
Migration may cause enrichment of the gene pool of such alleles that are being selected for, or anull the effects of selection through replishment of alleles that were selected against by nature.

Thymus is the primary lymphoid organ. In thymus gland, immature lymphocytes differentiate into antigen-sensitive lymphocytes. If thymus gland is removed from the body of a person, his immune system becomes weak. As a result the person's body becomes prone to infectious diseases.

When we say simple or complex organisms we are talking in terms of evolutionary history of an organism. A simple organism is considered to be primitive and has simple thallus organisation. The level of complexity of metabolism is also low. On the other hand a complex organism refers to a more evolveRead more
When we say simple or complex organisms we are talking in terms of evolutionary history of an organism. A simple organism is considered to be primitive and has simple thallus organisation. The level of complexity of metabolism is also low. On the other hand a complex organism refers to a more evolved form forming higher levels of structural and functional complexities. They are believed to have arisen from simple organisms.
Life style diseases are increasing alarmingly in India. We are also dealing with large scale malnutrition in the population. Is there any method by which we can address both these problems?
