- Please label this red onion cell image with a drop of water under the microscope. Include all relevant labels including: nucleus, cell wall, cell membrane, cytosol, vacuole, etc. Kindly explain why there's a large white stop at the top and bottom left. What conclusions do you draw from these results? Discuss this by referring to what type of solution this would be considered (eg. hypertonic, hypotonic or isotonic).Consider the solutions shown in the containers below. The composition of each solution is given in the image. 0.15 Mlactose isotonic hypotonic hypertonic crenation hemolysis no change A 0.28 M Urea B Fill the blank with the appropriate term from the list below. 0.16 MKCI The tonicity of the solution in container C isA microorganism was streaked onto 4 nutrient agar plates and the plates were incubated at different temperatures for 24 hours. The results are shown in the picture below. Which of the following statements best describes the proteins in the organism? (the same organism was streaked on all four plates) 4°C 37°C 64°C 25°C O proteins in this organism function optimally only at 37 degrees Centigrade O proteins in this organism function optimally only at 4 degrees Centigrade O The proteins in this organism function over a broad range of temperature O proteins in this organism function over a narrow temperature range.
- Explain how twitching motility is performed in bacteria. Multiple (at least 4 different) proteins should be discussed in your answer.A certain medium has the following composition: Glucose 15 g Yeast extract 5 g Peptone 5 g KH2PO4 2 g Distilled water 1,000 ml Tell what chemical category this medium belongs to, and explain why this is true. How could you convert Staphylococcus medium (table above) into a non-synthetic medium? a. What kind of medium might you make to selectively grow a bacterium that lives in the ocean? One that lives in the human stomach? Why are intestinal bacteria able to grow on media containing bile?Please label these two microspoe images of isotonic and hypertonic sheep's blood with as many details as possible. Please compare and contrast between the two and explain your conclusions based on each in details.
- What phenomenon would you expect to see occurring under a microscope when healthy cells of E. coli bacteria are placed in a dish of distilled water? Briefly explain the underlying mechanism.Consider a batch culture of sphere-shaped bacteria in a growth medium or broth, in which the mean cell diameter of the bacteria is 2.0 μm (micron). Show all your calculations and assumptions in answering the questions below: What is the volume of one of these sphere-shaped cells, expressed in liters? If there are 3 x 10^12 cells in one liter of this culture broth, what percentage of the volume is occupied by bacteria and what percentage is occupied by the cell culture broth (water only)? If the cells contain 80% water, what is the dry cell concentration, expressed as “grams dry weight/Liter of broth”? You should assume that the density of the cells dry mass is approximately 1.0 gr/cm3Give detailed Solution (Don't give Handwritten answer)
- When combining 1ml of lysosome solution with a concentration of 5mg/ml and 1ml of water what is the final concentration of the lysosome solution after adding 8.0 of a biuret reagent to the solution 2.5mg/ml 1mg/ml 0.5mg/ml 5 mg/mlGiven 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…please do not give solution in image format thanku Refer to the graph below, showing surface area and volume as functions of body size. Because of the relationships shown in the graph
