Answer:

The correct answer will be- Option-A

The suggestions made by them are:

1. The islands which remain farther from the mainland receive very few species as compared to the closest mainland.

2. Smaller island shows a high rate of species extinction as compared to the larger island.

Thus, option-A is the correct answer.

Answer:

Explanation:

This is because ionic bonds have high melting point because they are held together by strong electrostatic force which hold the opposite charges together. This make the lattice to have lot of ions and alot of energy is required to overcome it, hence they have high melting and boiling points.

Ionic bond is a bind that have electrostatic attraction between atoms of opposite ions.
