Consider the following statements regarding various vitamins in the human body, their chemical names, and deficiency disorders:
- 1. Deficiency of Vitamin A (Retinol) causes diseases like 'Xerophthalmia' and 'Night Blindness', and it is a fat-soluble vitamin stored in the liver.
- 2. Deficiency of Vitamin B-1 (Thiamine) causes 'Beriberi' disease, which affects the nervous system and heart functioning, and this vitamin is destroyed by excessive polishing of rice.
- 3. Vitamin C (Ascorbic Acid) is a water-soluble vitamin, whose deficiency causes 'Scurvy', characterized by bleeding gums and delayed wound healing, and it is synthesized in abundance by the human body itself.
- 4. Vitamin D (Cholecalciferol) also acts like a hormone, the deficiency of which causes bone diseases like 'Rickets' in children and 'Osteomalacia' in adults.
Which of the above statement(s) is/are completely true?
✓ Correct! Well done.
✗ Not quite — the correct answer is highlighted above.
Detailed Explanation
Statements 1, 2, and 4 are completely true. Vitamin A (Retinol) is fat-soluble and its deficiency causes night blindness; Vitamin B-1 (thiamine) deficiency causes beriberi and is depleted by polished rice; Vitamin D (cholecalciferol) deficiency causes rickets in children. However, statement 3 is false because Vitamin C (ascorbic acid) is not synthesized in the human body; it must be obtained from external diet (citrus fruits, etc.).

Consider the following statements regarding vitamins, their chemical names, and deficiency diseases: 1. Deficiency of Vitamin B1 (Thiamine) causes 'beriberi', which leads to problems like nervous system weakness and muscle paralysis, and it is a water-soluble vitamin. 2. Vitamin C (Ascorbic acid) is an antioxidant vitamin whose deficiency causes 'scurvy', characterized mainly by bleeding gums and delayed wound healing, and it remains stored in the body. 3. Vitamin D (Calciferol) is a fat-soluble vitamin synthesized by the skin in the presence of sunlight, and its deficiency causes 'rickets' in children and 'osteomalacia' in adults. 4. Vitamin B12 has the chemical name 'Cyanocobalamin' containing cobalt metal, and its deficiency causes 'pernicious anemia' because it is essential for the maturation of red blood cells.

Consider the following statements regarding a balanced diet and the role of various nutrients in the human body: 1. Carbohydrates and fats are the main energy-providing nutrients, where the oxidation of 1 gram of fat yields approximately 9.3 kcal of energy, which is more than double the energy obtained from an equal amount of carbohydrates. 2. Protein is called 'body-building food', whose main function is tissue repair and the formation of new cells, and its deficiency causes severe diseases like kwashiorkor and marasmus in children. 3. Vitamin A (retinol) is a water-soluble vitamin, whose deficiency causes eye diseases like night blindness and xerophthalmia, whereas vitamin C and B complex are fat-soluble. 4. Among mineral salts, deficiency of iodine causes the enlargement of the thyroid gland known as goitre, and iron deficiency hinders hemoglobin synthesis in the body, causing a disorder called anemia.

With reference to disaster management, Disaster Risk Reduction (DRR), and institutional structure in India, consider the following statements: 1. The Prime Minister is the chairperson of the 'National Disaster Management Authority' (NDMA) constituted under the Disaster Management Act, 2005, and this body promotes a 'proactive and prevention-oriented' approach instead of a 'reactive' approach to disaster management. 2. Under the global targets of the 'Sendai Framework for Disaster Risk Reduction (2015-2030)', a goal has been set to substantially reduce global human mortality by 2030, along with significantly reducing infrastructure damage and economic loss caused by disasters. 3. Community training schemes like 'Aapda Mitra' and 'Aapda Sakhi' are being run at the rural level by the Bihar State Disaster Management Authority (BSDMA) to reduce disaster risk, aiming to train local volunteers to deal with disasters like floods and lightning. 4. One hundred percent of the funding for the 'State Disaster Response Fund' (SDRF), used for relief operations after any disaster in India, is provided solely by state governments from their internal resources, with no financial participation from the central government.

Under the global targets of the 'Sendai Framework for Disaster Risk Reduction' (2015-2030), the goal is to substantially reduce global human mortality by 2030 along with massive cuts in infrastructure damage and economic loss due to disasters. 3. Community training schemes like 'Aapda Mitra' and 'Aapda Sakhi' are being run at the rural level by the Bihar State Disaster Management Authority (BSDMA) to reduce disaster risk, aiming to train local volunteers to deal with disasters like floods and lightning. 4.

Consider the following statements regarding the functions of hormones, vitamins, and various biomolecules in the human body and the diseases caused by their deficiency: 1. Insulin is a peptide hormone secreted by the beta cells of the islets of Langerhans in the pancreas, and it regulates blood glucose levels while stimulating the process of glycogenesis. 2. Vitamin D, also known as 'calciferol', is a fat-soluble vitamin that regulates the absorption of calcium and phosphorus in the body, and its deficiency causes 'rickets' in children and 'osteomalacia' in adults. 3. Iodine is essential for the synthesis of the 'thyroxine' hormone, the deficiency of which causes goiter, while severe deficiency of this hormone in adulthood leads to a condition called 'myxedema'. 4. Hemoglobin in the blood is an iron-containing protein that transports oxygen, and the anemia caused by its deficiency is always due solely to Vitamin B12 deficiency, with iron or folic acid playing no role.
