After the macrophage fails the Helper T Cell stimulates the B cells (create antibodies) if pathogen is extracellular and Cytotoxic T Cells (killer T cells, release perforin) if pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.

What is the maximum number of hours that food can be held in the food danger zone?
Agata [3.3K]
To answer this question, let us first mention what is food danger zone. Well, this refers to the temperature range in which bacteria grows faster in the food. The range is defined as 30 to 140 degree Fahrenheit or can be converted into 4 to 60 degree Celsius. Going back to the question, the maximum number of hours that a food can be held in the food danger zone is only 2 hours. Beyond this 2  hours, the food is not safe to be eaten and the person who dares to eat this food might get some illness and worst might experienced food poisoning.
