a. a mutation allowing moths to camouflage better on blackened tree bark
b. a mutation making staphylococcus aureus resistant to the antibiotic methicillin
c. a mutation inhibiting human immunodeficiency virus from attaching to and entering the cell
d. a mutation causing uncontrolled cell division
e. a mutation giving plant leaves a bitter taste to discourage herbivores from eating them

Explanation:

A mutation causing uncontrolled cell division (Option D) is harmful as it can lead to cancer. Options A, B, and C are beneficial mutations. Option A helps moths survive (camouflage), Option B makes bacteria resistant to an antibiotic (useful for bacteria's survival), and Option C inhibits a virus (protective for the cell). Uncontrolled cell division disrupts normal body functions.

Answer:

D. a mutation causing uncontrolled cell division
