Three students made different statements about cells and the human body. This is what they said:
Herman: "The human body is made up entirely of a collection of trillions of cells and things made from cells."
Felix: "The human body is surrounded by an outer covering. Inside this covering the body is filled in with cells and things made from cells."
Diandra: "The human body is a collection of trillions of cells and things made from cells contained inside an outer covering and inner coverings that contain organs."
Which student do you think best describes the human body?

Which is an advantage of having memory cells when a pathogen is encountered for a second time. a) the memory cells are what proliferate into clones of cells in response to the binding of an antigen. b) memory cells are vital to the primary immune response in that they immediately recognize pathogens even at the first encounter. c) memory cells are essentially effector cells that are short lived and attack antigens even without having a receptor specific to that antigen. d) it ensures that more lymphocytes with a receptor specific to a particular antigen will be present than in a host that had never encountered that pathogen.
