Compare the 10x and 40x measurements for Elodea cell length. Make sure you are comparing the averages in µm for the two objectives. How similar are the measurements?Elodea cell length: 10x has an average cell length of 116.7 um s, and 40x - 60.8 um. The differences between the two numbers are quite large. Thus, this leads to the fact that there were errors during the procedure.0.25 pts2. Assuming that at least some of the measuremens differ, which should you trustmore (10x or 40x) and why?I would trust more 40x because it gives the image of the Elodea cell bigger and cleaner. The measurements from 40x is more accurate since 40x is high power. 0.25 pts"3. Compounds that are not membrane permeable cause osmosis as we saw in this lab. Compounds that ARE membrane permeable themselves diffuse through the membrane and, therefore, do not cause osmosis. Formulate a hypothesis to addresswhether a newly-discovered compound is membrane permeable. In your hypothesis, make up a name for your compound. Remember that your hypothesis must be testable, e.g. using osmosis! Be specific: Your compound must have a name, and you must state what system you are going to test it on (it can't just be ""cells"")"Hypothesis: The effect of temperature on the permeable membrane of onion cells.0.25 ptsIndependent variable: different temperature.0.25 ptsDependent variable: the permeable membrane of onion cells.0.25 pts Negative control: room temperature.0.25 ptsTable 1 including formulas and cell references (1 pt):Table 2, incl. correct formulas, cell refs for means and std devs (0.5 pts):Table 2, Conversion to OMU using formulas and cell references (0.75 pts):Identification of unknown (0.25 pt):Total for Questions (1.5 pts):TOTAL PTS (4 possible):
