To verify that the unlabelled soft drink is diet soda rather than soda sweetened with fructose, we'll do a test of the presence of sugar in the drink. Normally a diet soda contains aspartame, an artificial sweetener derived from proteins. A reducing sugar test will reveal whether the drink contains sugar or not. Absence of sugar will indicate presence of artificial sweeteners. The Fehling's solution and Tollens' reagent are two chemical solutions that test the presence of sugar in the drink. The Fehling's solution gives off a red precipitate in presence of sugar and Tollens' solution gives off a silver precipitate in presence of sugar.

Pick the answer that best evaluates the following statement: "It has been said that land animals can't exist without plants but
creativ13 [48]

Answer:

c. This statement is true because plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants.

Explanation:

Green plants are autotrophs. They synthesize their food in the presence of sunlight, using carbon dioxide gas and water. Whereas animals are heterotrophs, they cannot make their food but use food prepared by green plants. Thus, plants are able to convert sun energy into food energy and animals must get their energy from plants or other organisms that eat plants. The statement is true.
