Facilitated diffusion does not use cellular energy.
Since the transportation of molecules occurs through the concentration gradient, it doesn’t use cellular energy for transportation of molecules.
Keystone predators can maintain species diversity in a community if they prey on the community's dominant species
Option B is correct.
What is meant by keystone predator?
A keystone species is usually a dominant predator whose removal allows a prey population to explode and often decreases overall diversity. other forms of keystone species are those, like coral or beavers, that significantly alter the habitat around them and thus affect large numbers of other organisms.
Are keystone species always predators?
A keystone species is usually , but not always, a predator. Just some predators can control the distribution and population of large numbers of prey species. the whole concept of keystone species was founded on research surrounding the influence of a marine predator on its environment.

Atoms gain energy during evaporation and boiling
When a liquid begins to boil, it means its molecules and atoms are gaining increased kinetic energy and the molecules are getting further apart and the liquid is beginning to turn to gas.
Explanation:
Gas begins to form in the liquid and lift to the surface as bubbles and escaping into the atmosphere. The vapor pressure of the liquid also overcomes the atmospheric pressure in this stage allowing the change of phase. This can only occur as long as the molecules and atoms of the liquid continue to gain energy. This is the reason that even though you keep heating the liquid, it remains at its boiling point temperature as it changes phase. This energy is referred to as the latent heat of vaporization.
