Carbohydrates are a whose primary function it to provide energy to the body. all digestible forms of carbohydrates provide 4 calories/g of energy. fiber, starch, and are complex carbohydrates, while glucose, fructose, and sucrose are simple carbohydrates. simple carbohydrates can be monosaccharides, like glucose and or disaccharides, like lactose and . complex carbohydrates include polysaccharides. starch consists of chains of glucose molecules. some starch chains are and harder to digest. other starch is much easier to digest and has chains. dietary consists of soluble and insoluble types, which both possess important benefits like reducing the risk of constipation, heart disease, and obesity. soluble fiber also reduce the risk of diabetes. glycogen is a highly branched polysaccharide created by a process called and is stored in the liver and muscles for later use. carbohydrates in the diet are said to spare from being used to provide for fuel for cells.

The accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. the accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. chimpanzees and gibbons are the most closely related the chimpanzee's closest surviving relative is humans orangutans are the primates least closely related to chimpanzees old world monkeys and gibbons are the most closely related
