Some white blood cells release chemicals upon encountering a pathogen. these chemicals attract other white blood cells to the point of infection. which of the following statements explains the feedback loop that occurs and predicts what would likely happen if the number of pathogens entering the body increases?
this is positive feedback. fewer white blood cells will be attracted to the site as the number of pathogens in the body increases.
this is negative feedback. fewer white blood cells will be attracted to the site as the number of pathogens in the body increases
this is positive feedback. more white blood cells will be attracted to the site as the number of pathogens in the body increases.
this is negative feedback. more white blood cells will be attracted to the site as the number of pathogens in the body increases.
