Zinc, iron and vitamin A deficiency can be sorted out by 

  1. Biofortification

  2. Bioremediation

  3. Biofertilizers

  4. Bioaugmentation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biofortification is the method in which the food is added or supplemented with the required nutrients. This process can be used for the production of the staple crops with higher levels of essential nutrients. The staple crops like wheat are fortified with zinc and the golden rice, rice is fortified to produce beta-carotene. Rice and sweet potato can be fortified with iron. The rural areas generally feed on the staple crops and suffer from nutrient deficiency.

A dietary deficiency disease is

  1. Anaemia

  2. Diabetes

  3. Tetanus

  4. Cretinism
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Dietary deficiencies are disorders which occur because of a lack of essential nutrients in the diet or because the body cannot absorb and process those nutrients once they are eaten. Most dietary deficiency diseases are caused by a lack of protein, vitamins, or minerals. Iron is necessary for the formation of certain proteins and enzymes. Haemoglobin, which is the oxygen-carrying protein in the blood, is iron-dependent protein. Iron deficiency can lead to anaemia, a lack of oxygen in the blood, which in turn can lead to fatigue and other complications. Good food sources of iron are liver, lean meats, legumes, dried fruits, and green leafy vegetables. 
Therefore, the correct answer is option A.

  2. Calcium carbonate

  3. Oxalic acid

  4. Lactic acid
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Gout is a metabolic disease in which crystals of uric acid gets deposited in joints, tendons and surrounding soft tissues.
  • Symptoms of gout increase irritation, inflammation of joins and tendon tissue, joints become hot red and swollen.
  • Hence gout is due to accumulation of uric disease.
  • So, the correct answer is 'Uric acid'.

Gout is a

  1. Deficiency disease

  2. Infectious disease

  3. Degenerative disease

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gout is a clinical condition. Gout is a kind of arthritis. It can cause an attack of sudden burning pain, stiffness and swelling in a joint, usually a big toe. These attacks can happen over and over unless gout is treated. Over time, they can harm your joints, tendons and other tissues. Gout is most common in men. Gout is caused by too much uric acid in the blood. Most of the time, having too much uric acid isn't harmful. Many people with high levels in their blood never get gout. But when uric acid levels in your blood are too high, the uric acid may form hard crystals in your joints. It's not a degenerative disease, infectious disease and deficiency disease. Thus, option D is correct.
