Body Mass Index (BMI) is calculated using which parameters? MCQ with Answer and Explanation

Body Mass Index (BMI) is calculated using which parameters?
A. Weight and height
B. Weight and age
C. Height and waist circumference
D. Fat percentage and muscle mass
Answer: Option A
Solution (By JKSSB Mock Tests)
Body Mass Index (BMI) is a simple index used to classify underweight, overweight, and obesity. It is calculated as a person's weight in kilograms divided by the square of their height in meters (kg/m2). While it is a useful population-level screening tool, it does not directly measure body fat and may not be accurate for athletes or the elderly.

Question #1
The number of ATP molecules produced from one glucose molecule during aerobic respiration is approximately:
A. 2
B. 4
C. 18
D. 36-38

Correct Answer: Option D


Explanation:
In eukaryotes, complete oxidation of one glucose molecule via glycolysis, Krebs cycle, and electron transport chain yields a net of about 36-38 ATP molecules (depending on shuttle systems). Glycolysis yields 2 ATP, Krebs 2 ATP, and oxidative phosphorylation 32-34 ATP. This is much higher than anaerobic respiration (2 ATP).

Question #2
Night blindness is caused by the deficiency of which vitamin?
A. Vitamin B1
B. Vitamin C
C. Vitamin A
D. Vitamin D

Correct Answer: Option C


Explanation:
Vitamin A (Retinol) is essential for the formation of rhodopsin (visual purple), a pigment in the rod cells of the retina necessary for vision in low light conditions. Deficiency of Vitamin A leads to night blindness (nyctalopia), where a person has difficulty seeing in dim light. Severe deficiency can also cause xerophthalmia and complete blindness.

Question #3
Rosie, the first transgenic cow, was engineered to produce human:
A. Interferon
B. Alpha-lactalbumin
C. Insulin
D. Growth hormone

Correct Answer: Option B


Explanation:
Rosie, the first transgenic cow, was created in 2000. She was genetically modified to produce milk that contained human alpha-lactalbumin, a protein found in human breast milk. Her milk was nutritionally more balanced for human babies than normal cow's milk, containing about 2.4 grams per liter of this human protein. This demonstrated the potential of transgenic animals for producing pharmaceutical or nutritional products.
