Answer:
c. A bacterial cell that lacked receptors on its surface for that antibiotic
Explanation:
If the bacteria lacks the receptors on its surface meant for that antibiotic then it will be best defense for the survival of that bacteria. It is receptors which interact with the antibiotic so as to permit it inside the cell. Therefore, in the absence of receptors, it doesn't matter how much antibiotic is lying in the external environment of that bacteria, the antibiotic will not be able to enter the bacterial cell to kill it. Hence, the bacteria will be able to survive easily.
The more you observe, the more you catch on
<span>We have two surfaces of nerve cell the outer and inner surface
- resting : when the outer layer ion charges more positively than the inner layer - depolarization : we have the counter part of this state
- repolarization : return to the polarization
- hyperpolarization : the inner negative ion charges will be more negative even more than the resting potential
I hope that this is the answer that you were looking for and it has helped you.
