Usually the opening of their tunnels aren't deep. The tunnels go across the ground, left or right. Rabbits can't climb up tunnels, so the openings should be close to the surface so that the rabbit can hop out easily. The tunnels are probably slightly slanted so it gets deeper without putting the rabbits off balance.
Rabbits can live up to about 8 years old, with a very few exceptions. There are some that live to be about 10 years old, however, the usual age that rabbits live to is 5 to 6 years of age.
For wild rabbits, it is anything up to 35mph.
There are many rabbits with ears sticking up. My Netherland dwarf rabbit, which is the smallest rabbit, has upright ears. Also dutch rabbits and rex rabbits do, to name some. Hope this is of some help :)
It depends on the rabbit if it is a healthy rabbit with no problems 8 years +

a large rabbits can have up to 15
Since a rabbit's gestation period is only ~30 days long, a rabbit certainly can give birth more than twice a year.
All kinds of rabbits need AT LEAST once weekly grooming. If you do not groom your rabbit, hair may build up in it's stomach, and your rabbit will get sick; rabbits cannot cough up hairballs. grooming prevents this from occurring.
Rabbits usually live up to 8 years, but sometimes up to 12 years. Wild rabbits will face predators, which will cause death. But, domesticated rabbits have the right environment.
That depends upon which breed of jackrabbit and which breed of rabbit you're comparing it with. Rabbit, and jackrabbits, can get up to somewhere around 30 pounds.
