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.

Answer:
The correct answer is d) genomic imprinting.
Explanation:
Genomic imprinting is a biological process by which specific modifications in the germ line that produce differences in the expression of the genetic material that is biochemically marked indicating its parental origin. The Prader-Willi syndrome is one of the best known and most studied examples in relation to pathologies produced by genomic imprinting. Prader-Willi syndrome is a complex genetic disease that is fundamentally neurological. Its appearance is due to a deletion of a fragment of chromosome 15 derived from the father.
