Answer 1

Answer:

C. The greatest amount of water loss occurs via production of urine by the kidneys.

Explanation:

Water loss through the production of urine by the kidneys is referred to as sensible water loss.

The kidneys can produce up to one litre of urine a day, sometimes even more or less and this depends on the body's needs which can in turn be influenced by the metabolic rate or the temperature of the environment.

Water loss from the body is sensible when the water is lost through the normal routes such as urine and faeces and it is insensible when the water is lost through respiration and sweating.

This definition validates options A and D.

B is wrong as water is usually present in the stool even though the body absorbs some.

C is wrong because the amount of water loss in the body varies according to different conditions and activities
