The correct answer would be that substance A is rice, and substance B is sugar.

For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.

Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.

Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Which example demonstrates metabolism? (brainly wont let me see other answers ;( )
Artist 52 [7]

The group of chemical processes in organisms that maintain life is known as metabolism. The three primary functions of metabolism are: converting the energy in food into energy that can be used to power cellular functions.

It is convenient to divide metabolism into two groups: Molecules are broken down during catabolism to provide energy. All of the substances that the cells require are synthesised during anabolism. Metabolic processes include the chemical reactions that keep you alive. One example of metabolism is the rate at which you burn fat and consume calories. the constant anabolic and catabolic chemical and physical processes that occur in living things and their cells. Specific areas of the cell host metabolic events. The cytoplasm is where amino acid degradation and some phases of glycolysis, fatty acid synthesis, and glycogen synthesis take place. Within mitochondria, certain metabolic pathways are located at particular points.
