To determine whether an acidic or basic solution, it is first necessary to compare the concentrations of the hydronium (H3O +) and hydroxide (OH-) ions in the solution.
In acidic solution, the concentration of H3O + ions is higher than that of OH- ions.
- In acidic solution, the concentration of H3O + ions is higher than that of OH- ions. Such a solution can be achieved by adding a small part of the H3O + ions, for example. Acid solutions have a pH below 7, the further away from 7 the pH of the solution is the higher its acidity content. According to Le Chatelier's principle, when a disturbance is caused to an equilibrium system, it tends to readjust in order to diminish the effects of that force. This means that if an acid is added to water, the H3O + ions will be in excess and the equilibrium will shift in the opposite direction to the left. Then these excess ions will react with the OH- ions. Thus, the concentration of OH- ions will decrease and the solution will become acidic.
- In basic solutions, the concentration of OH- ions is higher than that of H3O + ions. If we add a base to the water, it means that we will be adding OH- ions and, as explained in the previous section, by Le Chatelier's principle, the equilibrium of the water selfionization reaction will shift in the opposite direction, and the excess ions will react. with the H3O + ions, decreasing their concentration and making the basic solution. Basic solutions have a pH greater than 7, the farther from 7 and closer to 14 the pH of the solution, the higher the basification content.
The cell is the smallest level of organization and is composed of chemicals and atoms. These chemicals regulate the structure and functioning. Thus, the statement is true.
<h3>What is a cell?</h3>
A cell has been defined as the basic unit of the organization of organisms that have been known to be composed of chemicals, atoms, and molecules. They are bonded together to perform various functions.
The chemicals and elements involved are the fundamentals that provide the structural support and functions of the cell like the carbohydrates and lipids provides shape to the cell.
Therefore, the statement is true.

Your question is incomplete, but most probably your full question was, that cells are composed of chemicals, and both the structure and function of cells are regulated by basic chemistry principles. (True/false).
In the purest sense, no you cannot live without water. Your body is made up of an estimated sixty percent water and it is vital for life functions. You can live for approximately three to four days without water. However, when you are asking if you can subsist on anything else, many things that you might choose do in fact contain water. Other drinks, even sodas have water content, as do many fruits and vegetables. It is possible to get enough hydration from sources other than pure water, but not to survive without it entirely.
Answer:
B) Atoms of elements in the sun combine to release energy.
Explanation:
The process is called fusion, where atoms collide violently and release energy in the process, thus making new kinds of atoms.
Surface tension I think. which makes it feel like you are hitting concrete when you fall onto water from extreme heights.
