Explanation / Answer

1. The inability of blood to carry adequate oxygen, often due to lack of iron is anemia because other diseases not occur due to iron deficiency. Marasmus(not able to ingest protein, carbohydrates, and calories), Kwashiorkor( due to lack of protein in diet), Goitre( due to lack of Iodine).

2. Human relies on mainly on maize(corn), rice and wheat for the majority of nutrients around 60% that human consume.

3. Gene inserted into a plant to produce toxin for their protection is removed from a bacterium. Ex. about 10 years ago, Monsanto scientists inserted a toxin gene from the bacterium called Bt i.e. Bacillus thurigenesis into cotton plants to create caterpillar resistant variety. These genes carry the instructions for the production of a toxic protein.

4. DDT(Dichlorodiphenyltrichloroethane) is an organic chemical which has harmful effects on the environment so banned.
