The answer is scientific theory. It amalgamates scientific law about objects and events that are widely accepted and tested. Scientific theory rationalizes phenomenon, that is not rigorously understood, through science. Examples of scientific theories today are the special relativity theory of Albert Einstein.
Answer:
The correct answer is "a hypertonic solution".
Explanation:
Seawater is the most clear example of a hypertonic solution in nature. The concentration of ions in seawater are far more superior than the concentration of ions inside a plant or an animal cell, since seawater have an osmolarity of about 1000 mOsm/l. Therefore, at high tide a plant or animal cell will be in a hypertonic solution, and the cells must have adaptions to avoid cell shrinking and dead.
All of these are essential to survive
