Summary- The Bronx Zoo-based Wildlife Conservation Society (WCS) today applauded a decision today by the U.S. Fish and Wildlife Service to list the Tibetan antelope, also known as "chiru," as an endangered species. Through a series of expeditions to China's windswept Chang Tang Reserve over the past two decades, WCS had played a key role in sounding the alarm about the dramatic decline of this elegant animal due to poaching.
Questions-
Why is this species endangered? from poaching
What could prevent this organism from going extinct? less poaching and laws passed to stop the hunting of this animal
List three things you learned from this article in your own words. if animals go extinct many things could go wrong, fur is worth $15,000 on the black market, laws can be passed to stop the hunting of endabgered species
What impact would the absence of this organism have on its ecosystem/community? less ground would be fertilized and ground would be useless dirt

Climate Change Impacts Stream Life

http://www.sciencedaily.com/releases/2007/05/070504101355.htm
Summary:
Climate change is affecting streams and rivers. Streams and rivers are likely to be highly sensitive to climate. Climate change is also affecting the habitat of some animals living in those streams or rivers. Studies predict that every degree the temperature rises 21% of the stream decreses. The number of species could also decrease 12-25% in the next 50 years. The climate change also causes other problems such as effects of acid rain.

Questions:
Why is this species endangered?Fishing boats haul in many creatures besides the catch they want, including endangered animals such as dolphins and fish
What could prevent this organism from going extinct?designed a net with hatches at the bottom that should retain the haddock but let cleverer critters escape.
List three things you learned from this article in your own words.netted haddock never swim downwards.
What impact would the absence of this organism have on its ecosystem/community?it would effect the whales and other sea creaters that depend on it but not in a grave way.

Nanoelectrodes could provide bird flu test
Link:http://technology.newscientist.com/channel/tech/dn12999-nanoelectrodes-could-provide-bird-flu-test.html
Summary: The article opens describing finding the presence of specific genes could be as as hard as finding a needle in a haystack but new technology could put an end to that. To do this they wire a DNA strand up to a pair of nanotube electrodes and feed electricity through it. Since DNA with non matching base pairs lets considerably less current flow through it than a pair of matching strands, so they can use this to find certain genes.
What are the major functions of nucleic acids in the cell? To carry genetic information or form structures within the cell.
What are the differences in RNA and DNA? RNA is single stranded while DNA is double, while DNA contains deoxyribose, RNA contains ribose.
List three things you learned from this article in your own words. Electricity can be used to find certain genes, a 27 nm gap is the length of a segment of 80 base pairs of DNA, DNA with non-matching base pairs lets considerably less current flow through it than a pair of matching strands.
What impact would the absence of this organelle have on the cell? Cells woudlnt be able to carry any information to their host.
