Use the information below to answer the following multiple choice questions.
You are a scientist at a prestigious university. You are studying the effects of various temperatures on the function of a particular fictitious cellular protein, “toxeliminator.” The function of the protein in the cell is to break apart and eliminate toxins that invade the cell.
The following chart depicts your experimental set-up.
Test Tube Test Tube temperatures º C Contents of the test tube A Normal cell temp (35º) 2 ml toxin 2 ml toxeliminator protein B 55 º 2 ml toxin 2 ml toxeliminator protein C 75 º 2 ml toxin 2 ml toxeliminator protein D 95 º 2 ml toxin 2 ml toxeliminator protein
For your data, you measure the amount of toxin still left in each test tube 10 minutes after you have mixed the test tube ingredients. You have written down your results, but you have been a sloppy scientist! You mixed up the tubes and now you don’t know which measurement goes with which tube!! The following is your data.
Amount of toxin left in the tube (mL)
31. Which piece of data most likely corresponds to tube D?
a. 0. b. 1. c. 1. d. 2. e. None of the data would correspond with tube D
32. Which piece of data most likely corresponds with tube A?
a. 0. b. 1. c. 1. d. 2. e. None of the data would correspond with tube A
