Final answer:
Morbidity refers to the state of illness or the incidence of disease in a population, while mortality refers to the number of deaths from a disease in a population.
Step-by-step explanation:
Morbidity refers to the state of illness or the incidence of disease in a population. It can be measured by the number of cases of a disease expressed as a percentage of the population or as a rate per standard part of the population. Mortality, on the other hand, refers to the number of deaths from a disease expressed as a percentage of the population or as a rate per standard part of the population.
