Mammals such as the vampire bat have the ability to generate a urine with a concentration of approximately 3,600 milliosmoles (mOsm). If the concentration of their blood is approximately 300 mOsm, by producing a concentrated urine, their water loss is:.

Water is reduced by approximately 11/12.

Explanation:

Concentration of blood = 300 mOsm

COncentration of urine = 3600 mOsm

Water loss = ?

Let x be the water loss

So,

The concentration is 3600 mOsm from 300 mOsm of blood

From 1 mOsm of urine = the concentration of blood is mOsm

Negative sign indicates the loss.

water loss =

Therefore, the water loss is 11/12

i think the answer is c hope this
