7. Once anaerobic respiration takes place, are the effects permanent? Why or why not? If a tutor can give me the answer that would be very helpful

No, the effects can wear off which is why we breath constantly. When anaerobic respiration takes place it happens because of the lack of oxygen. So in order to make up for the lack of oxygen in that time anaerobic respiration repeats its cycle.

Option A

The moon's orbit around Earth results from the combination of gravity and inertia working on the moon

Explanation:

The physical law that declares that targets in movement serve to rest in action also performs a function in maintaining the planets in orbit. The gravity of the earth and the moon go coincidentally with the inertia to produce the orbits and hold them constant.

Gravity attracts the earth and the moon collectively while holding them isolated. The inertia renders the drift to keep speed and sustain moving. Collectively, this constitutes a rounded orbit as a kind of accommodation within the couple forces.
