Kangaroo rats are organisms found in the desert.  deserts have a hot, dry climate.  which three adaptations must kangaroo rats possess to survive in these conditions? (more than one)fewer sweat glandsnocturnal behaviorpresence of thin coatsincreased water retention abilitybright-colored skin

Answer: fewer sweat glands

Nocturnal behaviour

Increased water retention ability

Explanation:

The kangaroo rats have various adaptions to survive in the desert environment.

From the given options the three adaptations that they must have are as follows:

1. Fewer sweat glands - it is a known fact that even though the kangaroo rats live in such a hot desert environment, they do not sweat. This helps them to conserve the water and minimise water loss.

2. Nocturnal behaviour - Kangaroo rats are nocturnal in nature and for searching for the food at night they have large eyes. This is important as the temperatures at night are not as high as the day time in the deserts.

3. Increased water retention ability - the kangaroo rats do not sweat, they have a oily coat on their skin to minimise water loss and their kidneys produce 5 times more concentrated urine. With all these mechanisms they have increased water retention ability.

The kangaroo rats do not have a thin coat present on their body and neither do they have a bright colored skin that offers any advantage in the desert environment, thus the 3 options provided in the answer are the correct ones.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
