Nutrient Growth Medium

It is a culture medium or nutrient broth for all kinds of microorganisms to grow properly and create their colony. This matrix provides support to increase the population of microbes through the method of cell proliferation. It is regarded as the food material for those organisms. It is a type of in vitro mechanism, in which the development of life is processed outside the host body. It can be solid, semi-solid, or liquid in nature. Different kinds of cells develop in different types of media.

Question

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…

Which of the following options shows the correct order of fastest to slowest motion of chloride ions, glycine and proteins through the separating gel? Chloride ions > Proteins > Glycine Glycine > Chloride ions > Proteins Chloride ions > Glycine > Protein Protein > Chloride ions > Glycine You are trying to separate a mixture of AMP, ADP, and ATP using ion exchange chromatography. Select appropriate supplies for your experiment. A positively charged column, deprotonated buffer, NaCl of same concentration. A positively charged column, protonated buffer, NaCl of increasing concentration. A negatively charged column, protonated buffer, NaCl of increasing concentration You cannot separate nucleotides using ion exchange chromatography.
The standard curve to determine the amount of betacyanin is shown below. You extracted a red pigment from a beet disc (the mass of a disc is 2 g) using 10 ml of 20% ethanol solution. You measured absorbance of the solution above the beet disc every minute for a total time of 20 minutes. The increase in absorbance was linear during a period of time from 1 min to 10 min. The absorbance at 10 min was 0.8. Calculate the amount of betacyanin extracted from 1g of a beet tissue per minute. Explain your calculations. You can use Excel or a calculator.
Paclitaxel is used to treat ovarian cancer by infusion at a concentration of 0.6 mg/mL over 24 hours. A dose of 135 mg/m² has been prescribed for Sero. Sero is 1.06 m tall and weighs 92 kg. Paclitaxel comes in vials of 150 mg/25 mL.

The isoelectric point of eIF4a is 5.02. Students are given a sample of cell lysate containing eIF4A at pH 7.4. They are also provided with two buffers of pH 7.4 to use for ion exchange chromatography. One buffer has a very high salt concentration (1 M), the other has a low salt concentration (0.1 M). Mariela decides to use an anion exchange column, while Ashok chooses a cation exchange column. Who made the better decision? Provide a detailed explanation of why one student will end up with a purer sample of eIF4A. Which buffer will you use while washing away impurities (high or low salt), and which would you use to remove eIF4A from the column? Explain your choice.
