We’re back at it, more fun phytocannabinoids! We want to add Cannabidiol (CBD) to 15 mL of HL-60 cells so that you have a concentration of 12 hM. Our stock solution is 8 µM. What is the volume of stock solution we need?

Is there any other steps or is this the full solution? im still a bit confused.

Part a. You making 30 mo of agarose gel. Sybersafe A concentration 1000x. How much you will add......ul to the gel. b. You will be loading 20 your diagnostic digest onto your gal. The loading dye you have been provided is 5x concentrated. You will add..... ? ul to your sample before loading your gel.

Oops!  Your pipettor wasn’t set correctly and you only pipetted 87 µl of a 10-7 dilution when plating serial dilutions.  But, you noted this error in your lab notebook so you could correctly perform the calculation.  When this plate was grown, you counted 147 colonies on the plate.  What was the concentration of bacteria in the original, undiluted suspension?

This assignment was tricky and I had a hard time figuring it out you place 3 bags each containing 20% sucrose solution in three different beakers. What will happen to the weight of the bag in all three cases? Mention which beaker has hypo, hyper and isotonic solution with respect to the solution of the bag. So I have to figure out what the beaker 1 bag is ___ tonic And the beaker is ___ tonic Then what’s the weight of the bag in each beaker 1,2,4 and in beaker 2 I have to know what’s the bag _____ tonic and beaker is _______ then the third beaker 3 the same _______ tonic and the _________ tonic Because in beaker 1 the bag is 20% sucrose And the beaker is 40% sucrose In beaker 2 the bag is 20% sucrose and beaker is 20% sucrose Then for beaker 3 Bag in beaker 3 is 20% sucrose Beaker 3, beaker has 10% sucrose Then I have to mention if the weight of the bag will increase decrease or remain the same. Also what the objective of a microscope is 50x and that of the…
