Object 3-Form a crystal
Object 4- Spread out to fill their container
The correct answer to this question is C. Object 3- Form a crystal
Explanation:
The formation of crystals or crystallization is a process that occurs only in solids because in these particles are extremely organized and placed together, which forms defined structures or crystals. Additionally, due to crystallization and the organization of particles, solids always have a defined shape and volume, which means they do not adapt to a container. Moreover, particles only vibrate but do not move freely. Thus, the fact the substance form a crystal shows this is a solid.

Answer:
Natural selection
Explanation:
Natural selection is the process via which the frequency of adaptive mutations in the population increases. In adaptive mutations, the mutational changes that are caused through natural selection, make individual to survive better in that particular environment when passes through stress conditions like temperature, drought etc. through natural selection the fittest of all is selected (the one that had adapted in that environment).
