Final answer:
Microbes generally grow in warm, moist, and nutrient-rich areas of the body, while areas with intact and healthy skin and drier environments are not usually infected.
Step-by-step explanation:
The areas of the body where microbes generally grow are those that provide suitable conditions for their survival, such as warm, moist, and nutrient-rich environments. Examples of these areas include the underarms, the groin, and other skin folds. These regions tend to have a higher microbial load compared to areas with drier and less favorable conditions, such as the forearms and the top of the feet.
On the other hand, there are areas of the body that are not usually infected by microbes. These include intact and healthy skin, as it acts as a physical barrier against microbial invasion. In addition, areas with a relatively dry environment, such as the forearms, have lower microbial colonization compared to areas with higher moisture levels.
