The levels of organization from smallest to largest in living organisms are: atoms, molecules, cells, tissues, organs, organ systems, and organisms. Each level is more complex and is made up of the previous level.
Living organisms are highly structured and follow a fall in organization from smallest to largest. The smallest and most fundamental unit of matter is the atom, which consists of a nucleus surrounded by electrons. Atoms form molecules, where a molecule is a chemical structure consisting of at least two atoms held together by a chemical bond. Some biologically important molecules are macromolecules, which are large molecules typically formed by combining smaller units called monomers.
At a higher level of organization, molecules combine to form cells, which are the basic unit of life. A group of cells that work together to perform a specific function is called a tissue. Several tissues combine to form an organ, such as the heart or liver. Multiple organs then work together in an organ system, like the digestive system or circulatory system. Finally, all the organ systems in the body combine to form a complex living organism, such as a human. Thus, the levels of organization from smallest to largest are: atoms, molecules, cells, tissues, organs, organ systems, and organisms.

Answer: The evolution of our ancestors has produced the product of mankind
Explanation:
B) combustion
C) ignition
D) melting
Salts,mostly potassium and sodium are known as electrolytes and the body needs them in very specific amounts for proper function. Any significant imbalance of these levels can even be fatal if not corrected quickly.
The normal level of sodium in the body is 135 - 145 mmol/l in the blood while for potassium it's 3.5 to 5.0 mmol /l.
Loss of salts e.g. due to sweating may reduce these levels and so drinking plain water may replenish fluid loss but since plain water has no salts, the salt deficit remains and is in fact aggravated by the increase of plain fluid.
But drinking fluid that has electrolytes both replaces lost fluids and and at the same replenishes lost salts keeping the body functioning well .
