Mammals do whatever they have to in order to survive and protect their young. There is little help in the jungle or on the plains.
vegetable and water
Because they are woolly.
A kangaroo - in fact any mammal - would survive a mere few minutes in Antarctica.
No, because the sperm of the two animals are too different. Even if it did work, the baby/egg wouldn't survive.

If every mammal was the same size, it would be hard to hide from the predator or stalk the prey. Every mammal is the size it needs to be to survive.
It depens on what type of mammal .......the mammal that can survive the most cold weather would be a seal because they live in Antarctica and stuff like that and the temorater can be -50 sometimes very rarely they will die and sometimes if the seal gets very cold they will change colour like a purple or a light bleu One of my favourite animals is a seal.:D
Yes, like any living mammal, they need oxygen to survive, therefore they breathe.
E.Coli feeds on undigested nutrients in mammal intestines.
No one can yet live on mars. The only thing that isn't a mammal or cannot fly that can survive on mars, is the water bear. It can be seen under a microscope.
The only mammal that can survive in Antarctica all year is a human mammal.
Depending on what mammal you mean, most parent animals teach by example.
