Final answer:
A coroner can issue death certificates but cannot perform autopsies, while a pathologist can do both.
Step-by-step explanation:
A coroner is the person who can issue death certificates but cannot perform autopsies. They are typically elected officials or appointed by the government and are responsible for determining the cause of death and signing the death certificate. On the other hand, a pathologist is a medical doctor or veterinarian who can both issue death certificates and perform autopsies. They have specialized training in pathology and are able to examine bodies to determine the cause of death.
