Problem:An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen, via the Fab's variable region. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly (for example, by blocking a part of a microbe that is essential for its invasion and survival). Depending on the antigen, the binding may impede the biological process causing the disease or may activate macrophages to destroy the foreign substance. The ability of an antibody to communicate with the other components of the immune system is mediated via its Fc region (located at the base of the "Y"), which contains a conserved glycosylation site involved in these interactions. The production of antibodies is the main function of the humoral immune system.

Based on this passage, what is the role of antibodies in the immune response?
Solution:OK... The relevant information to answer the above question is: An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses.
neutralize pathogens such as pathogenic bacteria and viruses.

Student A:Concord grew in prominence throughout the 18th century, and some of its earliest houses survive at the northern end of Main Street. In the years following the Revolution, Concord's central geographical location made it a logical choice for the state capital, particularly after Samuel Blodget in 1807 opened a canal and lock system to allow vessels passage around the Amoskeag Falls downriver, connecting Concord with Boston by way of the Middlesex Canal. In 1808, Concord was named the official seat of state government. The 1819 State House is the oldest capitol in the nation in which the state's legislative branches meet in their original chambers. The city would become noted for furniture-making and granite quarrying. In 1828, Lewis Downing joined J. Stephens Abbot to form Abbot and Downing. Their most famous coach was the Concord Coach, modeled after the coronation coach of King George III. In the 19th century, Concord became a hub for the railroad industry, with Penacook a textile manufacturing center using water power from the Contoocook River. Today, the city is a center for health care and several insurance companies. It is also home to Concord Litho, one of the largest independently owned commercial printing companies in the country.
