Before a timber is converted into a wood, it has passed through series of processes before such conversion to a finished product

The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.
Option A
<u>Explanation:</u>
According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.
In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.
So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.
Answer:
Similar body parts may be homologies or analogies. Both provide evidence for evolution. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.
