Yellow-bellied sliders have a completely yellow plastron (bottom shell) but a red-eared slider will have ring-like markings on their plastron.
The red eared slider does, but the yellow bellied slider does not.
No you can not

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.
A slider turtle is basically like a category of turtles including the Yellow Belly Slider Turtle and the Red Eared Slider turtle.
I don't think there is such a thing as a yellow eared slider. Try looking up yellow bellied sliders. That's probably what you're looking for.
Yes, a Red Eared Slider has a spine.
by the way you have described it it sounds as if it is a yellow bellied slider, if it has to red marks on the sides of its cheeks/head it will be a red eared slider.
I know Red Eared Slider Turtles do that before mating. Males do it to females.
Yes. They are very similar to Red Eared Sliders except the "ears" are the same color as their jaw markings.
I dont know it depends on the red eared slider
