- Question
Kwashiorkor disease in children is caused by
Options- A. sufficient carbohydrates but less fats in diet
- B. sufficient carbohydrates and fats but deficient proteins in diet
- C. sufficient vitamins but deficient fats in diet
- D. sufficient fats but deficient vitamins in diet
- Correct Answer
- sufficient carbohydrates and fats but deficient proteins in diet
ExplanationKwashiorkar is produced by protein deficiency unaccompanied by calorie deficiency. It results from the replacement of mother?s milk by a high calorie-low protein diet in a child more than one year in age. Like marasmus, kwashiorkor shows wasting of muscles, thinning of limbs, failure of growth and brain development

Correct Answer: transfusion of contaminated blood and blood products
Explanation:
AIDS is caused by the Human Immuno deficiency Virus (HIV), a member of a group of viruses called retrovirus, which have an envelope enclosing the RNA genome. Transmission of HIV-infection generally occurs by (a) sexual contact with infected person, (b) by transfusion of contaminated blood and blood products, (c) by sharing infected needles as in the case of intravenous drug abusers and (d) from infected mother to her child through placenta.
Correct Answer: transcription
Explanation:
The process of copying genetic information from one strand of the DNA into RNA is termed as transcription. In transcription, only a segment of DNA and only one of the strands is copied into RNA. This necessitates defining the boundaries that would demarcate the region and the strand of DNA that would be transcribed.
Correct Answer: Excretory system
Correct Answer: 3
Correct Answer: 3
Explanation:
There are 3 double-layered membrane layers, which the protein has to pass to reach its destination.
Correct Answer: T wave
Explanation:
The mammalian heartis called myogenic (myo = muscle, genie = originating from). It means the heart beat or the activities of the heart are auto regulated which originates from a muscle called nodal tissue.In the human heart,heartbeat originates and contraction is initiated by a special modified heart muscle known as sinoatrial node. It is located in the right atrium; while the QRS waves are the depolarisation of the ventricles, which initiates the ventricular contraction.The T-wave represents the repolarisation,that is, the return of the ventricles from excited tonormal state.Hepatic portal system is the unique vascular connection that exists between the digestive tract and liver. This vein carries blood from intestine to the liver.
Correct Answer: High organic matter
Explanation:
All are correct except B as Aridisol is just like sand like soil as in Arid region e.g. In Rajasthan, so there will be very less amount of organic matter.
Correct Answer: Biological Oxygen Demand
Correct Answer: Respiratory system
Correct Answer: Vitamin A
