This is a three-part question You want to measure the blood oxygen level in a drop of blood using a pulse oximetry device. If you have a light source at 700nm, and 1mm of path length, what must be the concentration of: - oxidized hemoglobin in blood so that the light intensity at the output decreases to one tenth of the input intensity? - reduced hemoglobin in blood so that the light intensity at the output decreases to one tenth of the input intensity? - at the concentration you found in the second part, what is (Ii/If) for oxidized hemoglobin?

Consider a bi convex lens with radius of curvatures |R1| = 30 mm and |R2| = 180 mm, ct = 5 mm and glass is N-BK7. This is used as camera lens in order to image a man who is at 1 km away from the camera. We want to resolve 10 cm on his body. Assume that λ = 550 nm. Using zemax, determine the MTF value for the resolution of R = 80 lp / mm in image plane which is placed at paraxial focus.

In basic spectrophotometer, 1. Calculate the concentration of bovine serum albumin (BSA) if 40% of a light beam is transmitted through 2 cm of the cuvette (assume the molar absorption coefficient, e is 43,824 M-1 cm-1). 2. Calculate the %T, if the concentration of BSA in a 2 cm of cuvette is 0.025 mg/mL. and compare between 1 and 2
Lab students placed ten spinach leaf disks in each of three test tubes containing a baking soda solution and a control tube without baking soda. The volume of liquid in each tube and the temperature of the solutions were held constant. All tubes were placed an equal distance from a light source as indicated in the accompanying table. After 10 minutes, the amount of oxygen present in each sample was measured.

You have a mixture of the three molecules shown below that you are using Gas Chromatography to separate. Based on trends discussed in class, and using what you know about IMFS and Gas Chromatography, match up the three peaks in the GC scan to the molecules. Carefully read the ordering of peaks in the answer, this may not match how they are labeled in the diagram. Ignore differences in peak height and/or width.

This question is based on Bovine Serum Albumin I would like help on answering letters a-c. This lab examines the relationship between the absorbance of light by a solution at 595 nm and the concentration of the Coomassie Blue dye-BSA protein complex in the solution. State whether the following descriptions of the lab experiment are valid or not, and explain why you say Yes or No: a. The experiment would be significantly more accurate if absorbance readings were recorded for a range of wavelengths, not just for 595 nm b. The experiment has limited accuracy because it does not account for the absorbance of light by the other components (components that are not the dye-protein complex, such as excess dye that is not bound to any protein) of the solution. c. The absorbance reading measures practically all the protein content in the solutions
From the basic spectrophotometer technique, 1. Calculate the concentration of bovine serum albumin (BSA) if 40% of light the beam transmitted through a 2 cm of the cuvette (assume the molar absorption coefficient, e is 43,824 M-1 cm-1). 2. Calculate the %T, if the concentration of BSA in a 2 cm of cuvette is 25mg/mL. Compare between 1 and 2.
Write Cif only statement A is correct, Hif only statement B is correct, Eif both statements are correct, Mif both statements are incorrect. A. For the Lineweaver-Burk plot, the slope of the line reflects the ratio between the maximum velocity and the Michaelis constant. B. Meanwhile, the y-intercept is the maximum velocity.

Why do we utilize micropipettes when dispensing volumes in cell/molecular biology labs? a They are very technical pieces of equipment that require training to use. b Most often we need to move small volumes reliably and repeatedly. c Tips must be added to allow for the proper movement of the desired volume. d Each pipette is capable of giving a ten-fold difference in volume with appropriate tips.
From your results, which component had the highest Rf value and which had the lowest? Based on your answer from the previous question, what could be the reason behind some components having an Rf value higher than the others? Compare the qualities of the two components that rendered the highest and lowest Rf After performing the simulation, what do you think are the possible practical applications of chromatographic techniques that are relevant to your program?
