No, only female red eared sliders lay eggs.
No. Semi-Aquatic Turtles like the Red eared Slider will only lay eggs on land, not under water.
Yes
Your question is some what unclear but I will try my best to answer it. A female turtle doesn't have to mate to lay eggs. So even a lone female turtle may lay unfertilized eggs. If an adult male and female turtle are kept together then they will mate. If the female doesn't have sand or dirt to lay her eggs in then she may lay her eggs in the water or on whatever land possible. If you know your turtle is pregnant and put her in an separate enclosure for 4 months then yes she probably will lay eggs in there.
Depends what kind of female turtle we are speaking of. Some species lay their eggs in sand in a dry environment, but some are capable of doing it in the water.
She might be doing that because maybe it's scared of the environment. Did you recently change his or her environment? If your turtle follows turtle food you might have a solution. Lead your turtle into the water while letting it follow the food.
The female turtle will lay the eggs and the male comes along and fertilizes them. The female turtle will lay eggs even if there is no male turtle around.
it lays its eggs in the sand on a beach or near water and leaves the eggs there when they hatch they got directly the the water
All reptiles lay eggs. Reptiles are animals that have scales, are cold-blooded and lay eggs, like turtles and snakes and lizards.
