A prevalence study conducted from January 1 to December 31, 2017, on a population of 125,000 identified 500 cases of a disease. The incidence rate of this disease is 2 per 1,000. What percentage of the cases was newly diagnosed in 2017? A. 5% B. 50% C. 2% D. Answer cannot be calculated from this data set C. 2% Of 125,000 people, there were a total of 500 cases. An incidence rate of 2 per 1,000 means 250 new cases per 125,000 people. Thus, 50% are new cases. What mechanism is mos...

Modern cell theory - Answer- All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells. Energy flow (metabolism and biochemistry) occurs within cells. Cells contain DNA which is found specifically in the chromosome and RNA found in the cell nucleus and cytoplasm. All cel...
