“Prevalence” can be defined as:
a. The proportion of new cases of a disease that occurs in a population at risk over a set period of time.
b. The number of cases of disease in a population.
c. The number of new cases of a disease that occurs in a population annually.
d. The proportion of the total population that has a disease at one point in time.
e. The number of cases of a disease at the midpoint of any year.
Table 3.5 shows the number of deaths by age group in the United States in 2002 from all causes and incidents (unintentional injuries). Examine the rates mentioned below. Determine ,what to call each one then use the data to measure it as seen in the table.

- How do scientists use epidemiological transitions to understand how health has changed throughout human history? A. They can be used to describe long-term shifts and patterns observed in health and disease profiles of populations. B. They can be used to describe short-term shifts and patterns observed in health and disease profiles of populations. C. Epidemiological transitions cannot be used to understand how health has changed throughout human history. D. None of the abovearrow_forwardThe major disadvantage of crude rates is that: A. they may not allow for comparison of populations that differ in size. B. they do not permit comparison of populations that vary in composition. C. they are difficult to calculate from available data sources. D. all of the abovearrow_forwardA biologist determines the growth rate of a population of 198 frogs in a marsh near Beaverhill Lake, Alberta, to evaluate the quality of the environment. The researcher finds that, in one year, 34 were born, 86 died, 12 migrated into the marsh, and there was no emigration. a. frogs are considered an indicator species for the quality of the environment. Determine whether the growth rate of this population in one year is a cause for concern. if so, what might the concerns be?arrow_forward

The number of possible territories for robins is limited; thus when population sizes are high, a lower proportion of individuals can produce offspring. A. O B. In conditions of overcrowding, some desert pupfish living in ponds will emigrate to other ponds if given the opportunity. C.Predation on mosquitofish is high, regardless of population size. D. In conditions of high density, mice are more susceptible to mortality from heat stress. E. In a habitat patch with a high density of muskrats, a disease spreads more rapidly and results in higher mortality.arrow_forward
