The pressure from the air inside of it
Yes. A full basketball with medium to high pressure will clearly bounce higher than a flat basketball with low pressure.
The temperature of a room will effect the amount a ball will rebound (bounce) off the floor, off a backboard or rim. If a basketball is filled with air to the regulation pressure and then it is moved to a room with a higher temperature, the ball will soon start to bounce more. Alternatively if you move it a cooler room it will bounce less. This is because: Pressure = Volume x Temperature. As the temperature rises (assuming there is no leak in the ball to allow the volume of air to escape) the pressure on the inside of the ball will increase, this will increase the bounce of the ball. If, instead of the temperature rising, it decreases the pressure on the inside of the ball will go down and the bounciness of the ball will go down as well.

The regular air pressure in a basketball is typically between 7.5 and 8.5 pounds per square inch (psi). It is important to maintain the correct air pressure for optimal performance and bounce of the ball.
A basketball bounces higher depending on how much energy is transferred to it when it impacts the ground. Factors like the force of impact, the material and pressure of the basketball, and the angle at which it hits the ground can all affect how high it bounces.
Yes, the air pressure inside a soccer ball affects its bounce. An underinflated ball will have a lower bounce as there is less air pressure pushing against the ground to propel it back up. Conversely, an overinflated ball will have a higher bounce due to the increased air pressure inside.
Sure, when the ball gets compressed, the air pressure increases. This will help drive the ball up again.
If you mean OUTSIDE the basketball, then no. If you mean INSIDE the basketball, then yes.

Well, friend, when a basketball is filled with air, it becomes bouncy and easier to dribble and shoot. The air inside the ball helps it keep its shape and bounce back when it hits the ground. Just like adding a little sunshine to a painting, filling a basketball with air brings it to life and makes it ready for a fun game on the court.
