D Correct answer
Explanation

Pernicious anaemia caused when the body does not make enough red blood cells due to lack of cyanocobalamin (vitamin B12). Pyridoxine deficiency (also known as B6 deficiency) is a paediatric disease due to a lack of pyridoxine (or vitamin B6).

Multiple choice

What does "deficiency'' mean in the passage?

Directions: Read the passage given carefully and answer the question that follows.

The diet which contains adequate amount of all the important nutrients like carbohydrates, fats, proteins, minerals and vitamins, sufficient for the normal growth and development of the body is called a balanced diet. The constituents of balanced diet are - Carbohydrates, Fats, Proteins, Minerals (Salts), Vitamins, Water and Roughage, Carbohydrates are the compounds of carbon, hydrogen and oxygen. They are the main source of energy. The fats are the compounds of carbon, hydrogen and oxygen. The main function of fats in the body is to provide a steady source of energy. The proteins are highly complex organic compounds of carbon, hydrogen, oxygen and nitrogen. Proteins are very important for the growth and repair of the body. Kwashiorkor is a disease which occurs due to the deficiency of proteins in the diet of children whereas Marasmus occurs in the infants (small children) due to the deficiency of proteins. The metals, non-metals and their salts are called minerals. Our body needs minerals for its proper functioning.

  1. Lack of fats

  2. Lack of carbohydrates

  2. Marasmus

  3. Rickets

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

 The passage says, "Kwashiorkor is a disease which occurs due to the deficiency of proteins in the diet of children..." So, option 1 is correct.

Multiple choice

Match the vitamins with the appropriate deficiency diseases.

P. Thiamine 1. Dermatitis
Q. Pantothenic acid 2. Night-blindness
R. Biotin 3. Wernicke-Korsakoff syndrome
S. Ascorbic acid 4. Scurvy
5. Paresthesia

  1. P - 3, Q - 5, R - 1, S - 4

  2. P - 2, Q - 3, R - 5, S - 4

  3. P - 3, Q - 4, R - 2, S - 1

  4. P - 2, Q - 1, R - 5, S - 4

  5. P - 5, Q - 1, R - 3, S - 4
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The deficiency of thiamine (vitamin B1) causes Beriberi, Wernicke-Korsakoff-Syndrome. Lack of pantothenic acid causes Paresthesia diseases. The deficiency of biotin causes Dermatitis and Enteritis diseases. The deficiency of ascorbic acid causes Scurvy diseases. Hence, the correct match of codes is P - 3, Q - 5, R - 1, S - 4.

Multiple choice

Which of the following statements is/are not true?

P. The lack of panthothenic acid in diet causes nausea and vomiting. Q. Dermatitis of fingers and neck is caused by the deficiency of vitamin B3. R. Behavioural abnormalities in children is caused by the deficiency of ascorbic acid.

  1. Only P

  2. Only Q

  3. Only R

  4. Only P and Q

  5. Only Q and R
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The lack of panthothenic acid in diet causes nausea, vomiting and tremor of the outstretched hands. Dermatitis of fingers and neck is caused by the deficiency of vitamin B3 or niacin. Behavioural abnormalities occur in riboflavin deficient children. The deficiency of ascorbic acid or vitamin C causes scurvy, pain in bones and bleeding gums. Hence, statement R is not true.
