The tail of a kangaroo is used for both balance and propulsion, whether it is bounding along at top speed or walking slowly. Both the hind legs and the tail contain a lot of mitochondria, which are considered the powerhouse of a cell, and these mitochondria provide energy.
Recent research has also indicated that the tail is more important than the forelimbs when a kangaroo walks. A kangaroo cannot move its hind legs independently (except when swimming), so when a kangaroo moves slowly, it has always been thought to drag itself forward by its forelegs. This is not the case, however. Research has shown that the tail is vital for propelling the kangaroo forward. Scientists have discovered that there is much more propulsion energy provided by the tail than was previously thought.

No. Not at all.
No. Rat-kangaroos are marsupials and quite different to rats and kangaroo-rats, which are placental mammals. Rat-kangaroos do not have a hairless tail, and some species actually have a hairier tail than larger members of the macropod family.
Tree kangaroos vary in height. They range from 1.2m (120cm) to 1.65m (165cm) in length from their head to the tip of their tail.
No. At most, a kangaroo will balance on its tail and lash out with its strong hind legs in defence.
the function of a tail is to lift its body and to increase the speed of flight
No. Kangaroos have large, long tails. They are often as long as their back.
Kangaroos and other macropods such as wallabies and wallaroos use their tail to balance while jumping.
Not at all. Red kangaroos balance back on their strong tail, and use their powerful hind legs, which have sharp claws on them, to kick when then they fight. Human have neither a tail, nor sharp claws on powerful hind legs.
In this example, kangaroos is the simple subject, while Australia is the object of the preposition.
A kangaroos wrestler stands up on its tail and kicks it opponent with both of its legs.
The mate like most mammals, in spite of the tail issue.
