Answer 1

22. b. A high carbohydrate snack within 2 hours of exercise completion.

A high carbohydrate snack after exercise causes an increase in the blood glucose levels. Some of it is used by the body for various purposes and the excess glucose that is absorbed into the blood is converted into the glycogen by glycogenesis and stored in the body. This helps maintain the blood glucose levels and also the glycogen can be used later for energy.

23. d. Capillaries just under the skin.

When the blood enters the capillaries under the skin, it reaches the sweat glands which increase production of sweat. The sweat which is excreted onto the skin surface will get evaporated in turn cooling the surface of the body.

24. d. Hyponatremia

An athlete involved in prolonged physical activity looses a lot of electrolytes from the body through sweat mainly. These lost electrolytes should be replaced to maintain normal levels of electrolytes and the balance between various electrolytes. If he rehydrates only with water the electrolytes will not get replenished and their blood levels remain low. Among the given options, hyponatremia is the correct answer which means low sodium level.

31. e. Iron

It is one of the most important minerals required for various purposes in the body for its normal functioning. It’s demand by the body increases greatly during pregnancy. The increase in demand cannot be met by diet alone as availability of iron in food is very less. So in order to prevent the complications of less iron like anaemia, growth abnormalities it should be supplied to the pregnant mother in the form of supplements.
