A 7-year-old patient is admitted to the hospital with an intestinal obstruction. The patient is NPO and has a maintenance IV of 0.9% NaCl infusing at 35 mL/hr. The physician orders replacement IV fluid therapy for the child. The handoff report includes the following information: “Patient B had 80 mL of NG drainage for last 8 hr.” The PM nurse starts the replacement fluid IV infusion at 1500. How long (hours and minutes) will it take to infuse the replacement fluid? What is the completion time?

The profit-maximizing input levels of a monopolist are determined based on the condition; Question 2Answer a. d(p(y)/dy=MR(y)>p for all y < 0 so the marginal revenue product curve for a monopolist’s input is lower for all y < 0 than is the marginal revenue product curve for a perfectly competitive firm. b. d(p(y)/dy=MR(y)>p for all y > 0 so the marginal revenue product curve for a monopolist’s input is lower for all y > 0 than is the marginal revenue product curve for a perfectly competitive firm. c. d(p(y)y)/dy=MR(y)>p for all y < 0 so the marginal revenue product curve for a monopolist’s input is lower for all y < 0 than is the marginal revenue product curve for a perfectly competitive firm. d. d(p(y)y)/dy=MR(y) 0 so the marginal revenue product curve for a monopolist’s input is lower for all y >0 than is the marginal revenue product curve for a perfectly competitive firm.

The researcher suggests dividing the population of 6,500 stores into 2 strata: stores with weekly sales of $50,000 or less, and those with more than $50,000, where the sum of total sales is $357,315,581 and the strata ratio is 2 to 1. (a) Arrange the sample by stratum, divide the sample of 30 stores according to these two strata to obtain the size of ( N_h ) and estimate ( S_h^2 ) to determine the size of a stratified sample by proportional allocation with an overall precision of $400 and 95% confidence (create the sample by stratum randomly in Excel in such a way that they comply with the total sales sum, explaining step by step how you did this). (b) Obtain the stratified sample from the population and again estimate the overall mean and 95% confidence interval.

Synthesis in the "dark" reactions of photosynthesis. However, the Rubisco protein is not 100% efficient. Around 25% of the time Rubisco will activate molecular oxygen (O2) instead of CO2, resulting in the production of only 1 equivalent of 3-phosphoglycerate and 2-phosphoglycolate as an unwanted side product. This unwanted oxidase activity of Rubisco is known as photorespiration since it consumes O2. This oxidase activity of Rubisco is dependent on the ratio of dissolved O2 and CO2 in the cell. As temperatures increase, the solubility of dissolved O2 increases faster than that of CO2, making the side reaction more prominent. 2-phosphoglycolate has no metabolic function, and as a result, plants have developed a complex method to convert 2 molecules of 2-phosphoglycolate to CO2 and the 3-carbon amino acid serine. The name photorespiration comes from the fact that the pathway consumes O2 and produces CO2. Question 1) (5 points) Provide a reasonable arrow pushing mechanism for the oxygenase activity of Rubisco. Be sure to show all steps and include the important amino acid residues from the enzyme. Question 2) (5 points) Both C4 plants and CAM plants have developed mechanisms to prevent the unwanted oxygenase activity of Rubisco. Using diagrams and a few sentences, briefly describe the strategies used by C4 and CAM plants. Question 3) (5 points) Describe a simple experiment that you could design to determine if a plant is a C4 or CAM plant. Assume that you have access to 14C labeled CO2 and all the tools normally present in a biochemistry research lab. Be specific and describe what the expected result of the experiment will be if the plant is a C4 plant.
