Answer:
A
Explanation:
Some materials reflect light waves.
The answer is that they do not live on or in the body of a host.
The pancreatic juice is secreted by the pancreas. This pancreatic juice is secreted into the first part of the small intestine known as the duodenum. This pancreatic juice is rich in various enzymes that help in the digestion of various food components (carbohydrates, fats, and proteins). Besides being rich in enzymes, it is also rich in bicarbonate content. The bicarbonate works to neutralize the acidic chyme. This helps the enzymes to function and carry out digestion properly. If the pancreas fails to produce bicarbonate, then the function of enzymes will be altered, and the acidic chyme (coming from the stomach) will damage the small intestine walls.
Correct answer: C) Nutrients are circulated throughout the biosphere
Biogeochemical cycles are cycles by which essential elements of a living organism are circulated continuously. It consider the biological, chemical, and geological aspect of each cycle.
The most important biogeochemical cycles are nitrogen cycle, carbon cycle, water cycle, oxygen cycle and phosphorous cycle.
Biogeochemical cycle always have a state of equilibrium, and the state of equilibrium is attained when there is balance in cycling of element among the compartment.
Answer:
It consists of the mouth, or oral cavity, with its teeth, for grinding the food, and its tongue, which serves to knead food and mix it with saliva; the throat, or pharynx; the esophagus; the stomach; the small intestine, consisting of the duodenum, the jejunum, and the ileum; and the large intestine, consisting of the cecum, a closed-end sac connecting with the ileum, the ascending colon, the transverse colon, the descending colon, and the sigmoid colon, which terminates in the rectum. Glands contributing digestive juices include the salivary glands, the gastric glands in the stomach lining, the pancreas, and the liver and its adjuncts—the gallbladder and bile ducts. All of these organs and glands contribute to the physical and chemical breaking down of ingested food and to the eventual elimination of nondigestible wastes.
