The right answer is D.
Intermolecular forces lead to the assembly of microscopic systems. They are responsible for the cohesion of matter in most macroscopic phases. These are weak forces compared to covalent bond strengths. They do not modify the nature of the molecular species and only influence their mode of assembly. The most well-known intermolecular bonds are the Van der Waals bond and the hydrogen bond.
The greater the intermolecular forces, the more the aspect of the element will tend to be more condensed (gas <liquid <solid).
Answer:
C. They pollinate the flowers that only open at night.
Explanation:
A niche is the functional role an organism performs in the ecosystem. Simply, the question is asking for the role of nocturnal animals as pollinators.
- A pollinator is any organism the helps plants to transfer pollen grain from the anther of one flower to the stigma of another.
- This way, fertilization and crossing of genetic materials is achieved.
Nocturnal animals are animals that are very active at night. This is an evolutionary advantage for them because there is less danger at this point of the day.
Therefore, some nocturnal animals can help to pollinate flowers that only open at night.

The type of microscope that <span>can produce three-dimensional images of a cell’s surface is the electron-scanning microscope. In this type, beam of high-energy electrons is focused to project the correct projection of the cells. The projection of the cells are made up of signals of the surface.</span>
