The body uses specific methods to address pathogens that are causing illness. if a person has memory b cells against a certain pathogen, what will happen if that pathogen infects the person's body again?
a. they are likely to develop that disease.
b. they are much less likely to develop the disease a second time.
c. they are able to spread the disease to others through physical contact.
d. they are probably still sick with the disease.

They are much less likely to develop the disease a second time.

Memory B cells help your body prevent getting sick a second time once you get sick the first time. So for instance it may take about 15-16 days for your memory B cells to produce enough antibodies against this certain pathogen the first time, however once you get sick with the same thing the second time, these memory B cells will kick in and will take less time to fight off the pathogens in like 5 days. :)

Ok, before buying a burger. think of you diet and calories. how many calories are you suppose to eat a day. and look at how much fat, calories, salt is in it. if it is ok to you, then buy it. but if you think that it's to much fat and salt for you. don't buy !
