1.) What organ is the probable control center in the feedback loop below?
2.) What is the stimulus in the feedback loop below?
3.) Enumerate the 2 effector organs that process so that the body could return to a set point?
When the high blood glucose level is detected, the beta cells in the pancreas are stimulated to increase the production of insulin. These hormones are released into the bloodstream which will allow body cells to take up more glucose. Liver will be stimulated to take up glucose and store it as glycogen. These responses will allow blood glucose to decline to a set point thereby diminishing the stimulus to release insulin.

A chemist runs a reaction at 50C and determines its rate to be 0.00451M/s. If she increases the temperature to 80C, what will the rate of the reaction be?
The article “A Thin-Film Oxygen Uptake Test for the Evaluation of Automotive Crankcase Lubricants” reported the following data on oxidation-induction time (min) for various commercial oils: 87 103 130 160 180 195 132 145 211 105 145 a. Calculate the sample variance and standard deviation. b. If the observations were reexpressed in hours, what would be the resulting values of the sample variance and sample standard deviation? Answer without actually performing the reexpression.
If a cup of ice cream is selected. what is the probability that the cholesterol content will be more than 670mg?
Ozone (O3) in the atmosphere may react with nitric oxide (NO).
O3(g) + NO(g) = NO2(g) + O2(g)
