What would happen to the observed and specific rotation values if you were to halve the path length of the cell used while keeping the concentration the same?

Make a table with a scale of absorbance and the concentration of protein in Chromatin sample from the following data for excel graph Absorbance=660nm following data are of tubes with concern  A =0 B=0.036 C=0.011 D=0.001 E=0.027 F=0.020 G=0.032 H1=0.176 H2=0.183 I1=0.150 I2=0.171 also plot the graph??

You are planning an experiment to treat cells in culture with compound A at a final concentration of 10 µM. The stock solution concentration of compound A is 1 mM. What two controls should you have in your cell culture experiment using compound A? Explain both the type of controls and the concentration or volume of the treatments.

Why are the lengths of the cells usually approximated when we record their values for length?

An ocular reticle measures 1.2 mm in length. At this same magnification, an unknown cell measures 3 r.u. in length. What is the size of this cell in um? Show your calculation and include units.

If the potato cells were hypotonic to the surrounding solution, the surrounding solution itself would be what to the potato cells (hypertonic, hypotonic, or isotonic)?

Given this, if you used 6g of vitamin Z powder to make 20 ml of solution, what is the % concentration of this solution? (I gave the image since I don't know if that info is needed to solve this question.)It also gives a follow-up, if you can help here too: You work in a lab as a summer student. One of your tasks is to make sure that there is enough cell culture medium containing antibiotics to grow bacteria.  One day you realize that there is only 5 ml of 10% Antibiotic stock solution in the freezer. You decide to use it all to prepare the working culture medium with 0.01% antibiotic. In the lab there is plenty of growth medium without antibiotics. (Note: dilution in medium is like dilution in water). You remember the equation to make dilutions of stock solutions. You usually use this formula to calculate the required volume of a stock solution, but you realize it can apply here as well, even though the unknown is the final volume. So, you make that dilution.  Given that each bacterial…

What is the size in µm of a cell that is 135mm wide in my photo? The scale bar in the photo is 2.8cm long and represents 8µm.

In this part of the assignment, assume you have carried out the microscopic examination of the effects of osmosis in plant cells experiment The image in Figure 4 is of Elodea canadensis leaf cells in isotonic solution (normal saline). The image in Figure 5 is of Elodea canadensis leaf cells in 10% sucrose solution. The image in Figure 6 is of Elodea canadensis leaf cells in distilled water.   a. Determine cell size and vacuole size.  b. Calculate the percentage change in vacuole size for each treatment compared to the control. Use the formula: Experimental Size - Control Size/Control Size c. Based on these results, explain the tonicity of each treatment using experimental results to support your answer as would appear in the discussion section of a formal report (maximum four (4) lines). d. Was the percentage change in vacuole size for the experimental conditions relative to the control of similar magnitude? If the change was not of the same magnitude, explain the difference in effect…
