Outline, with a reason, another property that could be monitored to measure the rate of this reaction. 3c. Describe one systematic error associated with the use of the gas syringe, and how the error affects the calculated rate. 3d. Identify one error associated with the use of an accurate stopwatch.

The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 8.0 g • She put some solid potassium chloride into the graduated cylinder and weighed it. With the potassium chloride added, the cylinder weighed 48.930 g. • She added water to the graduated cylinder and dissolved the potassium…

2. Which of the following statements is FALSE regarding the log-kill hypothesis? a. It predicts the 100% eradication of cells after some period of time. b. It is an application of first-order kinetics. c. It predicts that cell counts decrease exponentially with repeated cycles of application. d. It applies to sterilization as well as other fields such as chemotherapy. e. Each cycle of application kills the same fraction (or %) of cells just prior to that cycle.

This module discusses the characteristics of carbohydrates, fats, and proteins. Enzymes are a special class of proteins that perform a wide variety of functions essential for the well-being of a living organism. In humans, a class of enzymes, which is of particular interest, are the liver enzymes. They break down all toxins encountered by humans. Research and describe the underlying causes for the elevated levels of any one of the liver enzymes described in a liver function test.Ask ONE (1) clarifying question about a topic you find difficult or want to learn more about from the concepts introduced in this module.In your response to your peer’s posts, locate a resource that may help address the clarifying question regarding the genetic topic in the initial post.

When an organic reaction is undergoing reflux, what are some potential errors (not human or instrumental) that would cause the reflux to be incomplete?

You have recently been hired as a researcher in a premier university. Your research deals with isolating novel antibiotics from Streptomyces species to offer solution in the growing problem of antibiotic resistance. Unfortunately, late one night you did not label the tubes and plates clearly. Now your promising work needs to be resolved with only a few of information retained. Gladly, you found the results in your notebook. Unfortunately, they are not labeled either. These graphs represent percentage of survival of bacteria after treatment with the antibiotics. Samples with antibiotic added (black bars); controls with no antibiotic added (grey bars). You need to identify which antibiotic was used per set-up (see figure). Listed below are some essential information. Antibiotic A: 0.5 kDa protein, targets peptidoglycanAntibiotic B: 20 kDa protein, targets peptidoglycanAntibiotic C: Cationic antimicrobial peptideAntibiotic D: Targets lipopolysaccharide Staphylococcus aureus: gram-positive…

Assuming you did the serial dilution correctly, how many coliform colonies would you expect to see on your 1:10 plate? Your 1:100 plate? Explain. (0) 1:10 plate? 1:100 plate ? 100 2. Coliform counts often increase dramatically in rivers and oceans near cities after rainstorms. Why? (do Internet research; use reputable sources; cite your sources appropriately in your answer)
