Would penicillin be expected to have an equal ability to kill both Gram-positive and Gram-negative bacteria? Why or why not?

No, due to the difference in Peptidoglycan layer

Explanation:

Since the mode of operation of the drug penicillin is to prevent the proper build-up of peptidoglycan in the cell wall of bacteria and bursting up its cell wall, Penicillin would have greater effect in killing Gram-negative bacteria with thin layer of peptidoglycan in their cell wall, unlike Gram-positive bacteria with a thick layer of peptidoglycan in their cell wall.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
