A. Viruses

B. Viroids

C. Bacteria

D. Fungus

Answer 2

Answer:

1. The shape of the Earth is almost spherical because of gravity. Gravity pulls Earth into a shape with maximum surface area (a sphere)

2. As the gravity of Earth increase as we approach the center, the farther you are from the center, the lesser the gravitational pull and the lower your mass.

3. At the center of the Earth, the gravitational pull is the same from all sides, thus the net force applied on you is zero.

4. Thus the gravity at the center of the Earth is zero, similar to space.
