Describe the trends that are shown in the graph; write two to three sentences that summarize the major features of the data in a form appropriate for the results section of a research paper: just the facts without interpretation.
The measured activity of both the control and drug-treated tissues first increases, and then decreases. The increase in activity in the drug-treated tissues is greater than in the control, about three-fold greater at the maximum (4-6 hours). The standard deviation associated with the drug-treated tissue is greater than that associated with the control tissue activity.
Write an interpretive statement that would be appropriate for the discussion section of a research paper. Propose a relation between the drug treatment and the observed data.
The data suggest that the drug increases the degree of activity increase, though it does not change the timing of the increase.
Here is a graph summarizing laboratory measurements. Identify features or details of the graph or its legend that you would expect to find in a published figure.
"activity" should have units The figure legend should explain what the column values represent. For example, is each column the average of multiple measurements, and if so, how many measurements were averaged? The figure legend should explain what the error bar shows - is this the standard deviation of the data set, or is it some other value (like a standard error)?
In your own words, explain what the "standard deviation" is a measure of; write your answer in the form of a complete sentence.
The standard deviation is a description of how much the individual observation values in a data set differ from the calculated mean.
If observation 2 (25.7 g) were replaced by a measurement of 20.0 g, what effect would this have on the sample standard deviation - would it increase or would it decrease? Explain why.
Because this observation has a large deviation (compared to the other data points) replacing it with a value that is more similar to the majority of the observations will have the effect of making the standard deviation smaller. Also note - it will also impact the calculated mean; the mean will decrease slightly.
Explain which component of a solution "acidity" is a measure of.
It has the higher concentration of "free protons" in solution.
The dashed line indicates that the two parts of the process occur in different cells. Identify the different energy costs or energy yields that accompany the transport of carbon dioxide in this way. How would the net cost or yield be different if this whole cycle occurred in a single cell?
When the cycle is divided in two different cells, one cell spends one ATP and one NADPH, and the second cell recovers one NADPH, and the CO2 is transferred in the process. If the whole cycle occurred in a single cell, the cell would spend one ATP, and there would be no net loss or gain of NADPH. No CO2 would be transferred; it would be released in the same cell.
