25. When the level of carbon dioxide in the blood is too high, the excess carbon dioxide reacts with water and produces carbonic acid. The carbonic acid causes the blood pH to become more acidic. When the blood pH becomes too acidic, chemoreceptors in the brain instruct the body to react and maintain homeostasis in blood pH. Which of these responses by the body would eliminate the excess carbon dioxide and help maintain homeostasis in the blood pH? a. Increasing the body temperature by shivering. b. Increasing glucose levels in the blood. c. Breathing more deeply and frequently. d. Decreasing the heart rate.

Normal body Normal body No change temperature (37 C) temperature (37C) 25. When the level of carbon dioxide in the blood is too high, the excess carbon dioxide reacts with water and produces carbonic acid. The carbonic acid causes the blood pH to become more acidic. When the blood pH becomes too acidic, chemoreceptors in the brain instruct the body to react and maintain homeostasis in blood pH. Which of these responses by the body would eliminate the excess carbon dioxide and help maintain homeostasis in the blood pH? Docrease in body Increaso in body temperaturo tomperature Shivering, vasoconstriction Thermoreceptors Norvo impuls0s sent to skin Hypothalamus Figure B a. Increasing the body temperature by shivering. b. Increasing glucose levels in the blood. c. Breathing more deeply and frequently. d. Decreasing the heart rate. 26. High blood glucose triggers cells in the pancreas to release the hormone insulin, which lowers blood glucose levels. Type 2 diabetes occurs when cells no longer respond to insulin. The blood glucose levels of several diabetic rats are measured and the rats are then fed a high carbohydrate meal. Which statement explains how a rat's blood glucose levels will most likely be affected by the high-carbohydrate meal? a. The rat's blood glucose level will increase after eating, which will cause insulin levels to rise until blood glucose decreases below the pre-meal level. b. The rat's blood glucose level will increase after eating and, after the rat is given an insulin injection, will quickly decrease to the pre-meal leve!. c. The rat's blood giucose level will increase for several hours after eating, and then will gradually decrease over several hours to the pre-meal level. d. The rat's blood glucose level will increase after eating and, even after the rat is given an insulin injection, will remain higher than the pre-meal level.
