The solution strength is 2mg in 1 ml. How many ml will be administered? Round to the nearest tenth.You have a sample – sample 1 - that has a concentration (✗) particles. From this you take 1 mL and add it to 99 mL water to create sample 2. You then take 1 mL of sample 2 and place it in 99 mL of water to create sample 3. And lastly, you take 1 mL of sample 3 and add it to 9 mL of water to create sample 4. What is the final dilution factor in sample 4? You may use drawings if it helps you understand and explain, though not necessary.
- To the right is an image of a dilution that was performed. The volume above the top arrow indicates the volume that should be transferred to the next tube (i.e. Tube 1). The volume listed at the bottom-right of tube 1 indicates the volume of diluent that should be added to that tube.

- Do you think standard plate counts are very accurate? Why or why not? When doing serial dilutions, why is it necessary to plate more than one dilution? You left a carton of orange juice on your counter for 3 days. When you taste it, it is very bubbly (as though it was carbonated), and it tastes more bitter than usual. (Note: acids taste bitter). What do you think could have happened? (Note: you can’t just say that bacteria grew—you must explain how the growth of the bacteria resulted in the changes in the orange juice.) Based on what you now know about the presence of bacteria on chicken and beef, why is it a good idea to use separate chopping boards for meat and for vegetables? Please help me thank youPrepare 50 plates of Sheep's Blood Agar using 100mm petri dish. Add 10% of blood to the media.
