Goshia [24]

Answer:

The correct answer is 327.78.

Explanation:

A mortality rate refers to the determination of the rate of the occurrences of deaths in a given population in the course of a particular time period. The formula for finding the mortality rate is:  

Deaths taking place in a given time duration / the size of the populace among which the deaths have taken place × 10ⁿ

The given population of the country is 250 million

The number of individuals died due to a certain disease is 819450

Thus, the mortality rate per 100000 can be calculated as:  

819450 / 250000000 × 100000 = 327.78 deaths per 100,000 people.

Pellarga disease is caused due to the deficiency of nicotinamide. Chemiosmosis transport the ions but neither oxidation nor reduction occur in this process of cellular respiration.

Thus, the answer is chemiosmosis.
