Answer:

its memory cells that provide quicker, larger and more efficient immune response upon second and subsequent exposure to an antigen

Explanation:

Immune system is the protective shield of organisms against various foreign pathogens. The immune system is categorised into two categories;

  • Innate immune system system is general and first barrier against any pathogen. It includes several components such as skin, hair and immune cells. It is by birth and can't be acquired
  • Adaptive immune system is specific and second line of defence against foreign pathogens, found only in vertebrates. It is also called as acquired immunity because it increases with exposure. It includes several components such as antibodies and immune cells.

When a pathogen breaches the innate immune system the adaptive immunity tries to encounter it. T helper cells of immune system stimulate the production of antibodies from plasma cells. Memory cells produced in this mechanism keeps the memory of that specific antigen and cause the stimulation of greater immune response on the second exposure of that antigen.

Answer:

It's memory cells that provide quicker ,larger and more efficient immune response upon second and subsequent exposure to an antigen.

Explanation:

Adaptive immunity or acquired immunity is a process whereby some specialized cells in the immune system destroy and eliminate invading pathogens and their toxic molecules they produced. It creates immunological memory through it memory cells of pathogens it encountered before , remember it and act against some antigens. If there is second contact with the antigen it's encountered before, it provide immune response.

Cross-contamination of food occurs when a. perishable foods are kept at room temperature for more than 2 hours b. a utensil cont
Nookie1986 [14]

ANSWER: B

explanation: from what I learned in culinary arts, this is kind of a trick question. Its not asking how foods can get contaminated, its asking how CROSS CONTAMINATION can occur. Cross contamination occurs in three ways think of it like this: food-to-food, equipment-to-food, and people-to-food. The answer has to be between B and C. But the answer is B, because the utensil is already contaminated and it is coming in contact with another food. The two or more food handlers working on the same food are not bringing anything contaminated into the situation. Unless they are contaminated (by they I mean their hands lol) then it cross contaminates but that's not it lol im 99% sure the answer Is B.
