Neither. The baby kangaroo, or joey, emerges from the birth canal, much as any mammal young does, but it is completely blind and hairless. Moving by instinct only, it crawls up the mother's fur to the pouch, where it attaches to a teat. The teat then swells in the joey's mouth, securing it through all the mother's movement so it cannot be dislodged, until it has grown for several weeks.

marsupials.
False. Newborn kangaroos are the size of a bean, about 2 cm in length.
The female kangaroo feeds her joey on mothers' milk. When first born, a baby kangaroo is about 2cm in length, and completely helpless. After birth, it crawls to the mother's pouch, where it latches on to a teat which then swells in its mouth, securing it in place. Here, the joey will stay permanently attached for several months while it continues to develop. The mother's milk is specially formulated to meet the needs of the joey, and contains no lactose. Female kangaroos are able to produce three different kinds of milk to meet the different nutritional needs of the joey at different stages of its development. It is not unusual for a female kangaroo to have a newborn in its pouch, an older joey in the pouch, and an almost-weaned joey that occasionally sticks its head inside to have a drink - and to be feeding each of them a different type of milk.
No. Baby kangaroo, or joeys, are born from the mother's birth canal at the base of the tail. Although blind, hairless and completely helpless, the joey (about the size of a bean) clings to its mother's fur, making a long and arduous journey completely by instinct, up to the pouch. The mother aids this journey by licking a pathway from the birth canal to the pouch. Once there, the joey attaches its mouth to a teat, which swells in its mouth to prevent it from being accidentally dislodged. The joey is in the mother kangaroo's pouch for about eight months, depending on the species. Sometimes a mother kangaroo will have two young of two different ages in her pouch at the same time. When this happens, she is able to produce different milk for each, depending on their age. Female kangaroos are in an almost permanent state of pregnancy, but they have "embryonic diapause", meaning they can suspend the development of the next embryo until conditions are right for it to be born (e.g. plenty of food).
Kangaroos have not been observed walking backwards.
Yes, it is generally true that baby urine is sterile.
No, not true.

Yes, this is what defines a marsupial, even more so than the fact that almost all marsupials have a pouch.
Yes, violet pouch fungus (Plicaria endocarpoides) are eukaryotic organisms. Eukaryotes are defined by having cells that contain a nucleus and other membrane-bound organelles, which is true for these fungi.
