Which of the following does a typical pathogen or agent of an infectious disease need to survive? Check all that apply. A. Energy B. Nutrients C. Water D. A favorable temperature

A typical pathogen or agent of an infectious disease needs all of the following to survive:

A. Energy: Pathogens need energy to carry out their functions, including growth and reproduction. They obtain this energy from the host organism they infect.

B. Nutrients: Pathogens also need nutrients to grow and reproduce. These nutrients can include a variety of substances, such as proteins, carbohydrates, and fats, which they also obtain from the host organism.

C. Water: Water is essential for all forms of life, including pathogens. It is involved in many biological processes, including the transport of nutrients and waste products.

D. A favorable temperature: Different pathogens thrive at different temperatures, but all require a certain temperature range to survive. For example, human pathogens typically thrive at body temperature (37°C or 98.6°F).

So, all of the options apply.
