The best answer would be HUMANS.
This is because organic compounds are essentially carbon based compounds and the human body is made up of many such compounds such as the protein that makes up skin, hair, nails, hormones and enzymes; gylcoproteins that are essential for cell membrane; fat found in skin and other tissues.
Answer is: <span>because dissolved compounds can crystallizing from solution during filtration and forming crystals on the filter paper or funnel.
</span>Recrystallization<span> is a technique used to purify chemicals by dissolving both impurities and a compound in an appropriate solvent, either compound or impurities can be removed from the solution, leaving the other behind.</span>

Answer : The correct answer is the Bonds were broken on the reactants and new bonds were formed on the products.
Explanation :
In the chemical reaction, some substances react together are called reactant and the substance are formed are called product.
During the chemical reaction, the atoms of reactants rearranged to make products. There are on atoms are added or taken away in the reaction. This is known as the conservation of atoms.
For example : carbon atom react with the oxygen to form carbon dioxide.

From the given diagram, we conclude that the arrangement of molecules are different on both side of the mixture of reaction.
On the reactant side, the red molecules bonded with red molecule and the black molecule with white molecules. On the other hand i.e product side, the red molecule bonded with black molecule and white molecule bonded with red molecules. The molecular arrangement are different on both side of the reaction mixture.
Therefore, the correct answer is the Bonds were broken on the reactants and new bonds were formed on the products.
Litmus is an indicator
Charged particles are ions
Acids contain H+ ions
Bases contain OH - ions
Hydronium ions are H3O+
Now, I have to take issue with the last one
A base of pH 14 is not a strong base, it would be a highly concentrated base. A strong base is a base that completely deionizes in water.
But technically, for the purpose of your answer strong base = pH 14
