Yes they do sleep. That is exactly what mine is doing right now. He sleeps a good bit during the day and whenever.
As often as they mate.
As any other snake, these snakes are born from eggs.
it dies right away when they are born.
8 inches for males 13 inches for females I would suggest the male
Yes, red eared sliders and yellow bellied sliders are both subspecies of "pond slider", in the wild where their range overlaps they mate quite often producing what are called "intergrades". The particular intergrade between a yellow bellied slider and a red eared slider often has features of both, large yellow markings on the head with a red corner.

Yes. Interbreeding between different subspecies is quite possible, such as red-eared sliders and yellow-bellied sliders, or Eastern box turtles and Ornate box turtles. Different species within the same genera is also possible, but the offspring are usually infertile. In very rare circumstances, two animals from different genera can interbreed, but they usually share a close evolutionary history.
Many reptiles lay bright yellow eggs. Yellow eggs are often a sign of the eggs not being fertilized so many reptiles have this capability.
Once a decade usually or even a century! Just joking! They lay unfertilized eggs about 10 times in 2 years
Turtles begin to get restless and try to escape their tank when they are almost ready to lay eggs. They also may begin to make digging motions with their back legs.
I assume you are referring to yellow-bellied sliders (Trachemys scripta scripta). Most sliders reach maturity at age 4 to 8, and maturity times and sizes vary a lot. In general, a female should be at least 8 inches long. It's unwise to house male and female turtles together unless you are breeding them. A male will harass the female to mate, and she may get fed up with him at some point, and let him have it--then you have vet visits to treat the wounds, which can be serious. Additionally, if he 'convinces' her to mate and she is really too small/immature, she could suffer physically from producing a clutch before her body is entirely ready. Effects may including hypocalcemia or egg binding (which requires surgery to correct in some cases...if it's caught. If not, it is deadly).
No, only female red eared sliders lay eggs.
it usually takes a week for toad eggs to hatch or 36 hours for tree frog eggs to hatch.
