Final answer:
The correct option is A. Factors affecting death can be both biological and environmental, and they contribute to the spread of diseases and increase the risk of death. Biological factors include diseases such as tuberculosis, malaria, pneumonia, influenza, and AIDS. Environmental factors include malnutrition, unclean water, poor sanitation, a lack of proper medical care, and overpopulation.
Step-by-step explanation:
Factors affecting death can be both biological and environmental. Biological factors include diseases such as tuberculosis, malaria, pneumonia, influenza, and AIDS, which are still major causes of death, especially in undeveloped countries.
Environmental factors include malnutrition, unclean water, poor sanitation, a lack of proper medical care, and overpopulation. These factors contribute to the spread of diseases and increase the risk of death. For example, drug-resistant pathogens and insecticide-resistant carriers make it difficult to control diseases like tuberculosis and malaria.
