Student A:Passage: Developed during live performances, an early version of the album was premiered several months before recording began; new material was recorded in two sessions in 1972 and 1973 at Abbey Road Studios in London. The group used some advanced recording techniques at the time, including multitrack recording and tape loops. Analogue synthesizers were prominent in several tracks, and snippets from recorded interviews with Pink Floyd's road crew and others provided philosophical quotations throughout. Engineer Alan Parsons was responsible for many distinctive sonic aspects and the recruitment of singer Clare Torry. The album's iconic sleeve was designed by Storm Thorgerson; following keyboardist Richard Wright's request for a "simple and bold" design, it depicts a prism spectrum, representing the band's lighting and the record's themes.

Problem:The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells. In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into three periods: interphase, the mitotic (M) phase, and cytokinesis. During interphase, the cell grows, accumulating nutrients needed for mitosis, preparing it for cell division and duplicating its DNA. During the mitotic phase, the chromosomes separate. During the final stage, cytokinesis, the chromosomes and cytoplasm separate into two new daughter cells. To ensure the proper division of the cell, there are control mechanisms known as cell cycle checkpoints.

Answer this question: when does cytokinesis occur in the cell cycle?
Solution:OK... The important part for answering this question is: During the final stage, cytokinesis, the chromosomes and cytoplasm separate into two new daughter cells.
the final stage.

Student A:Lactase is an enzyme produced by many organisms. It is located in the brush border of the small intestine of humans and other mammals. Lactase is essential to the complete digestion of whole milk; it breaks down lactose, a sugar which gives milk its sweetness. Lacking lactase, a person consuming dairy products may experience the symptoms of lactose intolerance. Lactase can be purchased as a food supplement, and is added to milk to produce "lactose-free" milk products.

Answer this question: where is lactase found in the human body?
Student B:OK... To answer the above question, the relevant sentence is: It is located in the brush border of the small intestine of humans and other mammals.
in the brush border of the small intestine.

Student A:The use of paper for hygiene has been recorded in China in the 6th century AD, with specifically manufactured toilet paper being mass-produced in the 14th century. Modern commercial toilet paper originated in the 19th century, with a patent for roll-based dispensers being made in 1883.

Answer this question: when was the first roll of toilet paper invented?
Student B:
OK... To answer the above question, the relevant sentence is: Modern commercial toilet paper originated in the 19th century, with a patent for roll-based dispensers being made in 1883.
1883.
