Arrange these components of the mammalian immune system as it first responds to a pathogen in the correct sequence
pathogen is destroyed
lymphocytes secrete antibodies
antigenic determinants from pathogen bind to antigen receptor on lymphocytes
lymphocytes specific to antigenic determinants from pathogen become numerous.
only memory cells remain
i -> iii -> ii -> iv -> v
iii -> ii -> i -> v -> iv
ii -> i -> iv -> iii -> v
iv -> ii -> iii -> i -> v
iii -> iv -> ii -> i -> v

The correct order is III -> IV -> II -> I -> V

Explanation:

During the initial immune response, the antibodies present on B-lymphocytes binds to the antigenic determinant or epitope present on the pathogen.

This interaction between pathogen and lymphocyte trigger the production of more lymphocytes specific to the particular antigenic determinant. These B-lymphocytes then differentiates into memory B cells and plasma cells. Plasma cells secrete the antibodies against the pathogen.

These antibodies destroy the pathogen by making the pathogen recognized by phagocytic cells or by activating the complement system of the body and at the end, only memory cells remain in the body which is used to generate a quick immune response in subsequent infection. Therefore, the right answer is III -> IV -> II -> I -> V.

The German inventor and printer Johann Gutenburg was the inventor of movable-type mechanical printing in Europe. Johann Gutenburg was born Johann Gensfleisch zur Laden, in Mainz. He was the third child of Freile zum Gensfleisch and his second wife, Else Wirick zum Gutenburg, whose name Johann adopted.

The printing press allowed the Renaissance to spread because it made new ideas available to a much larger audience. A printing press is a mechanical device for applying pressure to an inked surface. It's made of bronze and perhaps tin was also used in China for the printing of books. His invention revolutionized book making in Europe. Gutenburg was the key figure in spreading the Renaissance.

The Gutenburg bible was among the earliest major books printied using mass produced movable metal type in Europe. The bible that is a printed book that we study and pray through individually. The press was in many ways a great gift to the Church, enabling the Bible to become the world's bestselling printed book to date.

His printing press has been widely considered the most imporant invention of the modern era because it profoundly impacted the transmission of knowledge.
