A kangaroo can be found in a desert biome. How has it adapted to survive?
A
It doesn’t need a lot of water to survive
B
It hops over large distances to find water and food
C
It pants to cool itself down when it’s hot
D
All of the above
Explanation: 

Detailed explanation-1: -They drink less water than most kangaroos, and their urine is more concentrated so they will lose less water. They also look for food mainly at night or during dusk or dawn to avoid being out in the sun during the middle of the day. Instead, they spend their days trying to stay cool in the shade of trees and bushes.

Detailed explanation-2: -Animal adaptations The absence of sweat glands, and the concentration of urine are other physical adaptations made by desert animals. Because fat intensifies heat, a unique physical adaptation of some desert animals is the storage of fat in humps or tails, rather than throughout the entire body.

Detailed explanation-3: -Adaptations. The kangaroo rat is almost perfectly adapted to life in the desert. They can survive without ever drinking any water, getting needed moisture from their seed diet. They have excellent hearing and can even detect the silent sound of an owl approaching.

Detailed explanation-4: -It has longer eyelashes that protects the eyes from getting damaged by the sand during a sandstorm. Camels can close their nostrils completely to stop the entry of sand into the respiratory passage from the environment. Hump of the camel can store fat which helps them survive without food for months.
