LF1 displays a characteristic fluorescein-like absorption band in the visible region centred at 490 nm and weak fluorescence. Upon addition of Pb2+‚ the fluorescence intensity intensity of LF1 increases by 18 fold with the absorption and emission maxima. This turn-on response is reversible‚ treatment with the chelator TPEN restores LF1 fluorescence back to within 5% of baseline levels. Binding assays using the method of continuous variations (Job’s plot) are consistent with a 1:1 Pb2+:LF1 complex

As I strolled down Poinciana Drive on a Tuesday morning‚ I was suddenly bombarded by the loud speaker knocking music coming out of the back of a dark blue Nissan Maxima. The elderly lady walking ahead of me immediately spun around stunned by the profanity filled lyrics now floating through the air by the rap artist Lil’ Wayne in his hit single “Alphabet Bitches” ‚ “These are my bitches‚ my alpha bitches‚ these are my bitches my alphabet bitches‚ say what‚ I get bitches‚ say who‚ I get bitches”.

Place your answer on the answer sheet. There are 50 questions‚ each worth 2 points. 1) In 1985‚ Alice paid $20‚000 for an option to purchase ten acres of land. By paying the $20‚000‚ she bought the right to buy the land for $100‚000 in 1992. When she acquired the option in 1985‚ the land was worth $120‚000. In 1992‚ it is worth $110‚000. Should Alice exercise the option and pay $100‚000 for the land? A) Yes. B) No. C) It depends on what the rate of inflation was between 1985 and 1992

Monsoon is traditionally defined as a seasonal reversing wind accompanied by corresponding changes in precipitation‚[1] but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea.[2] [3] Usually‚ the term monsoon is used to refer to the rainy phase of a seasonally-changing pattern‚ although technically there is also a dry phase. The major monsoon systems of the world consist of the West African and Asia-Australian
