A. they protect the cell from dehydration B. they are called attachment pili to distinguish them from the pili used to transfer DNA during conjugation C. they are used to attach the cell to its substrate or to other prokaryote D. they are hair-like projections that aid in attachment.arrow_forwardJohn Smith is a pig farmer. For the past five years, Smith has been adding vitamins and low doses of antibiotics to his pig food; he says that these supplements enhance the growth of the pigs. Within the past year, however, several of his pigs died from infections of common bacteria, which failed to respond to large doses of antibiotics. Can you explain the increased rate of mortality due to infection in Smith’s pigs? What advice might you offer Smith to prevent this problem in the future?arrow_forward
