    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.

  5. Asked: October 7, 2021In: Class 12 Biology

    What would happen to immune system, if thymus gland is removed from the body of a person?

    Ananya Jaynti
    Added an answer on October 7, 2021 at 8:36 am

    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 evolved form forming higher levels of structural and functional complexities. They are believed to have arisen from simple organisms.
