Answer 1

Solution. 26
The correct option is option D - Potassium, which is present in high quantities in the mentioned foods. It works in tandem with sodium ( found in common salt) to generate the required action potential for nerve impulses to occur.

Solution 29:
The correct option is option B - Night blindness. Vitamin A deficiency leads to the cornea to become very dry, leading to clouding of the front of the eye. Scurvy occurs when there is a lack of vitamin C. Blood doesnt clot when there is insufficient vitamin K. Iron deficiency is the most common cause of microcytic anemia.

Solution 45:
The correct option is option C - Cushing's syndrome, which is characterised by increased secretion of adrenocorticotropic hormone (ACTH) from the anterior pituitary.
Acromegaly is due to the overproduction of growth hormone
Cretinism is stunted growth and development as a result of maternal hypothyroidism.
Diabetes mellitus is a condition when the body cannot produce sufficient insulin to absorb blood sugar.

Solution 57:
The correct answer is option C - Increased heart rate. This is caused due to release of hormone adrenaline ( the fight-or-flight hormone) This in turn increases the blood pressure. During stress, blood sugar levels increase, in anticipation of the fight-or-flight.
Increased urinary output s usually a sign of diabetes
