yes
What kind of turtle is it? Turtles like painted turtles and slider turtles should be fine. But turtles like musk, mud, or soft shell turtles would have trouble reaching the surface to breath. Do some research on your turtle and find out what their habitat should be. Deep or shallow.
Red-eared slider turtles usually can only breed successfully if they have hibernated before, and turtles kept in tanks rarely hibernate. There is a miniscual chance your turtles will breed if they have not hibernated.
Every 6 months you should take the Red Eared Slider Turtle to the vet
Yes, as long as it is large enough to accommodate the turtles. While a hatchling can live in a 10 gallon aquarium, it will soon need a 100 gallon aquarium as these turtles get up to 12" in shell length.
they think they need water
All turtles need to have mated in order to lay eggs, unlike birds who will lay infertile eggs, turtles won't.
No they do not breathe under water. They have lungs. Aquatic turtles such as the red - eared slider can hold their breath for 3 - 4 hours.
Any normal filter will work. Chacha on!!

The slider turtle would go to a pond or other fresh water body o water. A place where it would be happy with friend turtles, food, and other things they need.
My baby turtle sleep underwater. They need to be able to get on land and in fact they enjoy it! My turtles do fine out of water for an hr or more because they also sleep out of water. Turtles need time out of their terrarium so they can work out.
