Problem:Passage: The urinary system, also known as the renal system or urinary tract, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH. The urinary tract is the body's drainage system for the eventual removal of urine. The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein. Each kidney consists of functional units called nephrons. Following filtration of blood and further processing, wastes (in the form of urine) exit the kidney via the ureters, tubes made of smooth muscle fibres that propel urine towards the urinary bladder, where it is stored and subsequently expelled from the body by urination (voiding). The female and male urinary system are very similar, differing only in the length of the urethra.

Question: Based on this passage, list the main functions of the urinary system?
Solution:OK... To answer the above question, the relevant sentence is: The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.
to eliminate waste from the body , regulate blood volume and blood pressure , control levels of electrolytes and metabolites , and regulate blood pH.

Student A:"Last Kiss" is a song released by Wayne Cochran in 1961 on the Gala label. It failed to do well on the charts. Cochran subsequently re-recorded his song for the King label in 1963. It was later revived by J. Frank Wilson and the Cavaliers, Pearl Jam and several international artists, including the Canadian group Wednesday, with varying degrees of success. The song was one of several teen tragedy songs from that period. The song's opening lyrics mirror the opening lyrics of Septimus Winner's "Der Deitcher's Dog".

Based on this passage, who sang the original song the last kiss?
Student B:OK... To answer the question, consider the following: "Last Kiss" is a song released by Wayne Cochran in 1961 on the Gala label.

Student A:Context: Transition state analogs (transition state analogues), are chemical compounds with a chemical structure that resembles the transition state of a substrate molecule in an enzyme-catalyzed chemical reaction. Enzymes interact with a substrate by means of strain or distortions, moving the substrate towards the transition state. Transition state analogs can be used as inhibitors in enzyme-catalyzed reactions by blocking the active site of the enzyme. Theory suggests that enzyme inhibitors which resembled the transition state structure would bind more tightly to the enzyme than the actual substrate. Examples of drugs that are transition state analog inhibitors include flu medications such as the neuraminidase inhibitor oseltamivir and the HIV protease inhibitors saquinavir in the treatment of AIDS.

Question: compound designed to mimic the structure of a transition state?
Student B:OK... To answer this question, we should know that: Transition state analogs (transition state analogues), are chemical compounds with a chemical structure that resembles the transition state of a substrate molecule in an enzyme-catalyzed chemical reaction.
Transition state analogs.
