Is ampicillin or solvents (such as acetone) more effective at killing off bacteria, in general? Explain...
Is it possible to have a colony exhibiting ampicillin resistance and not fluorescence? Explain why or why not. in general and experiment based off E.coli and plamid pGFP
Justify please! DISCUSSION POST #2 If bacteria are grown on plates with ampicillin and X-gal, explain which color colonies, white or blue, would contain bacteria with recombinant plasmid.
5. Consider the following solvents for potential use in a Grignard reaction. a) Acetone b) Methanol c) Tetrahydrofuran For each solvent, indicate (yes or no) whether or not the solvent will be suitable for use in a Grignard reaction. If yes, explain why. If no, explain why not, and draw a balanced reaction scheme for the side reaction (NOT the desired reaction) that will likely occur instead
Which is more polar, Acetone or Water? Explain why.
choose: which defense mechanism is more effective against gram positive bacteria than gram negative bacteria? a- inflammation b- B-galactosidase c- peptidyl transferase d- lysozyme
Explain why more spore forming in 48-hour incubation of bacteria than 24 hours? For microbiology
An antiseptic such as 70% alcohol dissolves lipids. It was observed that Gram-positive bacteria were more resistant to alcohol than Gram-negative bacteria. Is this an expected result? Why or why not, explain in detail.
Explain why hydrogen peroxide would be more effective as a disinfectant on inanimate surfaces as opposed to living tissue?
Why is Streptomycin only effective against bacteria, and not archaea as well? I thought its mechanism of action had to do with its binding site on the 30S ribosomal subunit, but archaea have this as well, so why is it not effective against both? For reference, I was asked to explain how the mode of action of each antibiotic relates to the organisms in each domain. is down partenere a cyclo acteria on the basis of sensitivity to antimicrobial chemicals....
Please explain why the centralized management approach is more cost-effective than the decentralized management approach.
