Answer:

d) per capita population growth rate

Explanation:

Per capita growth rate of a population is symbolized as "r" in population growth models. Here, "r" is the rate of change of a population on a per capita basis. The change in the population includes both an increase and a decrease in its size.  The per capita growth rate is calculated by subtracting the birth rate of the population from its death rate. Therefore, r= b-d. Here, "b" is the birth rate of the population and "d" is the death rate.

Paul [167]

Answer: Backdating the time required for food found in the stomach of the deceased to digest. Since digestion can't continue after death.

Explanation: The time taken for food to get digested can be employed to depicts time of death. This process involves understanding the period of time that usually takes the food found in the gastric of the deceased to calculate the time of death.

Different foods has varying time of digestion, so therefore, the gastric content is a good indicator to determine time of death by the doctor who is carrying out autopsy, since digestion does not continue after death.

However, it is established by scientist that food takes up to 4-6hours in the stomach depending on the size and type of food. Hence, if the status of the food found in the deceased stomach is noted accordingly and the time taken requires for digestion is also noted، the doctor can deduce the time of death accordingly from this two points.
