Human come from apes.
Dinosaurs exist.
Answer:
1. gravel of the sand: a part is dissolved and the remainder is grouped at the bottom of the beaker.
2. drop of sunflower oil: It is not absorbed and heaps on the surface of the water contained in the beaker.
Explanation:
Gravel of the sand is a polar substance. This means that this substance has the ability to dissolve and mix with water in a system in which both were placed together, such as a beaker, for example. However, the beaker limits the amount of water, which limits its ability to dissolve polar substances. Therefore, depending on the quantity, the gravel of the sand, when placed in a beaker with water, will dissolve, in parts, what is not dissolved will accumulate in the bottom of the beacker, because the gravel of the sand is denser than the water.
With the drop of sunflower oil the exact opposite happens. This is because drops of oil are nonpolar substances, which means that they do not have the ability to be dissolved in water. This means that when dropped into the beaker with water, the drop of sunflower oil will not dissolve, but will pile up on the water surface, because it is less dense than water.

a fusion reaction in the sun
Explanation:
The model most likely represents a fusion reaction in the sun. In nuclear fusion two light atoms combines to give another third one. This third atom is more massive.
The reaction is accompanied by a great release of energy.
Model:
Atom 1 + Atom 2 ⇒ Atom 3 + energy
- Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of a large amount of energy.
- The energy released provides the needed temperature for another set of atoms to fuse.
- The process establishes a series of chain reactions and releases a great deal of energy.
