Q: The Browns traveled to Indianapolis to take on an Andrew Luck-led Colts offense. The Colts were able to score in the first quarter as Andrew Luck ran for a 3-yard touchdown making the score 7-0 for the only score of the game. The Browns responded in the 2nd quarter coming within a point when Brandon Weeden found Greg Little on a 14-yard pass (with a failed PAT) making the score 7-6. Then, Luck ran for another touchdown this time from 5 yards out to make the score 14-6 at halftime. The Browns came within a point again in the 3rd quarter as Weeden found Josh Gordon on a 33-yard pass making the score 14-13 but the Colts wrapped things up with Adam Vinatieri's 38-yard field goal followed by a scoreless 4th quarter making the final score 17-13 as the Browns' road record at this point of the season was 0-4 while their record overall was 1-6.

Q: The Patriots travelled to the Metrodome for a Monday Night Football showdown with the Minnesota Vikings, who, like the Patriots, boasted an excellent run defense. The Patriots, who took to the air with a spread offense for the entire game, opened with a seven-play, 86-yard strike that ended with a touchdown pass from Brady to wide receiver Reche Caldwell. Their next drive was for 93 yards which resulted in a 23-yard Gostkowski field goal. And just before halftime the Patriots moved 74 yards in 11 plays to take a 17-0 lead on a nine-yard scoring toss to tight end Benjamin Watson. The only Vikings score of the game came on a 71-yard punt return by Mewelde Moore in the third quarter; Laurence Maroney immediately answered on the ensuing kickoff, with a 77-yard return to Minnesota's 21-yard line, his second return of over 70 yards in as many weeks. The Patriots' lead grew to 17 after a seven-yard touchdown reception by Brown with 9:03 in the third quarter and then became 31-7 with a touchdown catch by Jackson. The Patriots defense also intercepted four passes from quarterbacks Brad Johnson and Brooks Bollinger. On Bollinger's first drive after relieving Brad Johnson he was sacked three times in a row for a net loss of 23 yards. With their fourth straight victory, the Patriots advanced to 6-1.This was the Patriots' third and final game played in the Metrodome.

A: Which team scored more touchdowns, the Patriots or the Vikings?

Q: Like water and carbon, nitrogen is also repeatedly recycled through the biosphere. This process is called the nitrogen cycle. Nitrogen is one of the most common elements in living organisms. It is important for creating both proteins and nucleic acids, like DNA. The air that we breathe is mostly nitrogen gas (N2 ), but, unfortunately, animals and plants cannot use the nitrogen when it is a gas. In fact, plants often die from a lack of nitrogen even through they are surrounded by plenty of nitrogen gas. Nitrogen gas (N2 ) has two nitrogen atoms connected by a very strong triple bond. Most plants and animals cannot use the nitrogen in nitrogen gas because they cannot break that triple bond. In order for plants to make use of nitrogen, it must be transformed into molecules they can use. This can be accomplished several different ways ( Figure 1.1). Lightning: When lightening strikes, nitrogen gas is transformed into nitrate (NO3 ) that plants can use. Nitrogen fixation: Special nitrogen-fixing bacteria can also transform nitrogen gas into useful forms. These bacteria live in the roots of plants in the pea family. They turn the nitrogen gas into ammonium (NH4 + ) (a process called ammonification). In water environments, bacteria in the water can also fix nitrogen gas into ammonium. Ammonium can be used by aquatic plants as a source of nitrogen. Nitrogen also is released to the environment by decaying organisms or decaying wastes. These wastes release nitrogen in the form of ammonium. Ammonium in the soil can be turned into nitrate by a two-step process completed by two different types of bacteria. In the form of nitrate, nitrogen can be used by plants through the process of assimilation. It is then passed along to animals when they eat the plants. Turning nitrate back into nitrogen gas, the process of denitrification, happens through the work of denitrifying bacteria. These bacteria often live in swamps and lakes. They take in the nitrate and release it back to the atmosphere as nitrogen gas. Just like the carbon cycle, human activities impact the nitrogen cycle. These human activities include the burning of fossil fuels, which release nitrogen oxide gasses into the atmosphere. Releasing nitrogen oxide back into the atmosphere leads to problems like acid rain.
