Why methylene blue, a basic dye, can be used to stain cytoplasm, a basic structure? Why cytoplasm is basic and at the same time negatively charged? I am confused with the terms "basic dye" and "acidic dye". Is it true that a basic dye is positively charged? If so, why is cytoplasm which is negatively charged called basic materials? Could you please explain more on these?
Identify which antibiotic between C and D was used per set-up. Describe each of the results by including the implications given on the graphs as to why it used Antibiotic C or D. Antibiotic C: Cationic antimicrobial peptide - these positively charged antibiotics are attracted to the negatively charged cell wall and membrane. They are hydrophobic, and they insert into the membranes to create pores. Antibiotic D: Targets lipopolysaccharide
