What discovery led darwin to develop his theories on adaptation?
a. the galapagos islands contain a range of habitats.
b. the galapagos islands originate from volcanoes.
c. the birds darwin found in the galapagos were different types of finches, not separate types of birds.
d. many of the organisms in the galapagos lived in hostile environments.

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.

In this assignment, you will analyze an example of speciation by researching the finches of the galapagos islands. then you will answer questions to construct explanations and draw conclusions based on the information you gather. someone plz !

Is dna the same in every cell in the human body explain your answer
