The answer is: It spins a sample to separate based on density.
Fusion and gravity

outer pressure of nuclear fusion in as much as the inner force of gravity
balances it.
Answer:
Mitosis it's the Anaphase

other animals, the heart pumps the blood into the body cavities, spaces or
sinuses, where the blood surrounds the tissues.
