Why are polysaccharides more difficult to digest than monosaccharides? a. polysaccharides are made of lipids. b. polysaccharides contain phosphorus. c. polysaccharides are much larger molecules. d. polysaccharides contain peptide bonds.

The correct answer is C. Polysaccharides are much larger molecules.

Explanation:

Polysaccharides are made up of a long chain of sugar molecules called monosaccharides that are joined together by glycosidic bonds. They are classified as structural and storage polysaccharides.  

Polysaccharides are more difficult to digest than monosaccharides because they are very large and require to be broken in smaller forms of monosaccharides so that it can easily be absorbed by the body.

Therefore polysaccharides like glycogen and starch are broken down in small intestine by pancreatic amylase into monosaccharides like maltose and dextrins and then absorbed in the body through villi present in small intestine.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."    

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds
