To determine:
The definition of term demography, demographic transition, zero population growth and age structure.
Explanation of Solution
Demography: Demography is described as the study of human population. It deals with the size, distribution and the composition of the population in different regions.
Demographic transition: It is a theory that suggests the possible transitions occurring in a population of a country or a geographical region. In this theory, the birth rate increases and death rate decreases significantly.
Zero population Growth: It is referred to a condition, in which number of individuals in a population neither increases nor decreases. In this case, the birth rate or the number of individuals born in a region is equal to the death rate, i.e., number of individuals died.
Age structure: It is a graphical representation of the proportion of individuals of different ages. It gives an idea about the number of individuals in a particular age group and also gives an insight of the sex ration in different age group. Given below is a typical representation of age structure of a population.

- Please help me calculate drug dosage from the following information: Patient weight: 35 pounds, so 15.9 kilograms (got this by dividing 35 pounds by 2.2 kilograms) Drug dose: 0.05mg/kg Drug concentration: 2mg/mLarrow_forwardA 25-year-old woman presents to the emergency department with a 2-day history of fever, chills, severe headache, and confusion. She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D.
