Answer:
The correct answer will be option- C.
Explanation:
Dehydration is the loss of water from the body in the response to which body undergoes physiological and metabolic changes as:
1. The hypothalamus produces Anti-diuretic hormone or ADH from the posterior of the pituitary gland which produces its effect on the kidney to reabsorb the water.
2. The body produces renin, angiotensin II and aldosterone which increases the permeability of the distal convoluted tubule and the collecting ducts.
3. The extracellular blood or the blood becomes more concentrated due to dehydration.
Thus, option- C which is that renal tubules decrease water reabsorption is the incorrect option as water absorption is increased in the kidney.
Answer:
2.1 liter.
Explanation:
Homeostasis may be defined as the phenomena of the maintenance of the internal environment of the body irrespective of the change in the external or internal environment.
The water consumption is important for the body as the human's body consists of more than 60% water.
The water consumption can be calculated as follows:
Water consumption = water loss - water produced.
Water loss from exercise = 2000 ml = 2 liter, 300 ml was lost during from metabolism = 0.3 liter.
The water produced = 200 ml = 0.2 liter.
The water consumption = 2 L + 0.3 L - 0.2 L
Total water consumption done by the body = 2.1 liter.
Thus, the answer is 2.1 liter.
