Emanuel's body metabolizes caffeine at a rate of 14.4% per hour (so the amount of caffeine in Emanuel's body decreases by 14.4% each hour).a. If Emanuel consumes a cup of coffee with 86 mg of caffeine in it, how long will it take for Emanuel's body to metabolize half of the 86mg of caffeine?hours Previewb. If Emanuel consumes an energy drink with 210 mg of caffeine in it, how long will it take for Emanuel's body to metabolize half of the 210mg of caffeine?hours Previewc.

The thermoneutral zone is the range of body temperatures over which an animal can maintain a constant basal metabolic rate. Which of the following patterns about thermoregulation is true? A. Below the lower critical threshold, animals must decrease their metabolic rate in order to maintain body temperature B. Animals living in the arctic have higher critical temperatures than do animals in the tropics C. When outside temperatures are below the lower critical temperature for an animal, animals in the arctic increase their metabolic rate faster than do animals in the tropics D. All of the above E. None of the above
With regard to thermoregulation in humans, what could be considered an accurate consequence of the outside temperature dropping below the lower critical temperature? A. The individual will begin to breathe in less oxygen and exhale less carbon dioxide. B. The metabolic needs of the individual will increase if they remain below the lower critical temperature for sufficient time-frames. C. Capillaries (i.e. blood vessels) near the surface of the skin will dilate in order to allow blood to circulate more freely throughout the organism, distributing heat to raise temperature. D. The person's Basal Metabolic Rate will be lowered to match the Standard Metabolic Rate of an ectotherm of comparable size. E. Hormones from the hypothalamus will be released, which lead to the initiation of a positive feedback response that amplifies muscle contraction, leading to shivering.

You are a researcher seeking to determine if an experimental drug can effectively treat hyperglycemia, a condition characterized by excess glucose in the blood, often associated with Type I diabetes. You select 24 hyperglycemia patients to study, and you give half of them a pill containing the drug you are testing and the other half a placebo (a pill that lacks the drug ingredient). After an evening of fasting, you measure the amount of glucose in their blood the next morning. Write the null and alternative hypotheses appropriate for your study. Which treatment is your control group, and why does your experimental design require a control group? Describe the structure of a carbohydrate, and what are the functions of carbohydrates in the body? What test that we have used before in lab could you use to measure the amount of glucose in their blood? Describe how you would use this test to measure the amounts of glucose in their blood serum samples. Identify the dependent variable…
In Type 1 Diabetes, the body is unable to maintain homeostasis of blood glucose because the pancreas does not make insulin. Draw a graph to predict how blood glucose levels (mg/dl) would change with time in the 2 hours after consuming sugar in a person with Type 1 Diabetes versus a healthy person.
Which of the following is false? a. to Citric acid is the main product of post-mortem enzymatic degradation of glucose and glycogen and affects the pH of tissues. b. Amino acids and proteins when heated can serve as a source of free ammonia, in addition, sulfur amino acids and the proteins that constitute them are precursors of H₂S. c. pH of the meat, species and gender of the animal, genotype, age, diet are aroma factors in meat and its derivatives can be considered in the formation of compounds responsible for d. Lean tissue is responsible for the meaty aroma common to all species.
GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect normal levels of dissolved glucose (70. to 105 mg/dL), using a blood sample that is as small as 5.0 mL. Calculate the minimum mass in milligrams of glucose that the new system must be able to detect. Be sure your answer has the correct number of significant digits.
