Answer:
Cellular energy
Explanation:
Osmosis is the movement of water from a less concentrated to more concentrated solution across a semi-permeable membrane. Cellular energy is not required in osmosis because it is a passive process. Osmosis is technically more or less the selective diffusion of water molecules across a membrane that selectively locks out other larger molecule like ions. Water will, therefore, move from the solution where there are more water molecules to the solution with fewer water molecules.

The other three are already well established.
Answer:
Pleiotropy
Explanation:
Pleiotropy is a condition that occurs when one gene affect several other phenotypic traits that are not related. The autosomal dominant allele of the genetic disease called blue sclera, is pleiotropic. It has the potential of causing also fragile bones and deafness which are entirely unrelated traits. Genetic mutation of a gene is the most likely explainable reason for the connection of these traits together.
Because you cannot test it or observe it.
A scientific theory are created through the scientific method, in the scientific method you need to be able observe it and experiment.
In a desert, the climate is “hot” and “dry”.
