hi everyone this is my question : how do E.coli colonies look like on EMB plate ?
it is a microbiology question. thank you
E. Coli appears as large, blue -black colonies often with a green metallic sheen.

How would the Lorenz Curve used to calculate the income inequality look like when everyone in a country gets exactly the same wage?
hi everyone, this is a biochemistry question I need help with explaining. Please show/explain your steps or work, thank you in advance! B) Outline a known moonlighting function of one of the enzymes of the TCA. C) Outline how the TCA is regulated.
Hi Everyone, This is a biochemistry homework question, Im not sure how to even answer this, but please help by explaining what the correct answer can be.Thank you in advance 7) If an alien suffered a single-base deletion mutation what impact will this have on their mRNA? How can the original reading frame be restored?
Hi Everyone, this is a physical chemistry question. Please help by explaining the steps to help solve the practice problem. Thank you in advance! 5. Calculate the molar internal energy of a diatomic gas using statistical thermodynamics. Assume that all vibrational motions are in ground state.
public speaking class Subscribe The question I'd like everyone to consider this week is: Do the examples or stories used in a speech have to be trup? If so, why? If not, under what circumstances would it be okay to use a fictional or hypothetical account? In considering this, also talk about your feelings in regard to this example: Once, a young man in my class presented a persuasive speech encouraging everyone to wear a seat belt. In the speech,...
hi, I would like help with corrections! I recieved my homework back and the teacher circled 6.9 M ^-1 s^-1. How do you reach this answer? How do I apply the formula for second order? : 1/[A] - 1/[A] = kt ( this was just what the formula in my textbook looked like but I know when you google something there is slight variation in each, and each person likes to write there formula a little differently that helps them)...
Question 2: EcoRI, EcoRII, and EcoRV are all restriction enzymes found in E.coli. How does E.coli prevent these enzymes from digesting its own DNA? Question 3: When performing a restriction digest it is necessary to incubate the enzymes and the DNA together to give the enzymes time to work. Given that we're using enzymes isolated from E.coli, a human symbiont, what temperature would you incubate the enzymes at, and why? Question 4: Why do DNA fragments migrate across the gel...
Hi everyone, I'm quite stuck on the second question of the problem and would like some help! Please let me know if you can help solve it! Thanks! An electric point charge of Q1 8.95 nC is placed at the origin of the real axis. Another point charge of Q2 3.41 nC is placed at a position of p 3.22 m on the real axis. At which position can a third point charge of q -8.04 nC be placed so...
Hi everyone! Can someone solve these and explain them? I haven't solved any questions like these. Thank you! You have a coffee cup calorimeter (isolated system, heat is measured at constant pressure mix two solutions (Ti-22.07 °C) in the coffee cup. Solution 1 is 50,0 mL - 50.0 B) of HI. Solution 2 is 50.0 mL (50.0 g) of UNKNOWN MOLARITY of LiOH. You kn the LiOH solution is the limiting reagent. Upon mixing the temperature of the mixture cup...
