summary:a man named Levinson and he belives that kidney cells transporting ions, and could be well suited to making a miniature battery.He suggests that such biobatteries might be ideal for powering devices inserted in the body, such as insulin pumps or pacemakers.and so he went for it
Questions: What reactions does this enzyme catalyze?it transports ions to the kidney
How is the cell affected if this enzyme is removed? i think it effects it in a bad way because the ions are needed for transporting information
List three things you learned from this article in your own words.ions are transported to the kidneys,the cell culture can draw oxygen, and producing biobatteries with the kind of voltages needed to run medical devices.
What impact would the absence of this molecule have on the cell? bad we need them to help transport

New Test Improves Detection Of Liver Cancer
Link:http://www.sciencedaily.com/releases/2007/08/070808132051.htm
Summary:The main idea of this passage is Cancer of the liver is very difficult to detect, and it is a major cause of death in Asia and Africa, with rising incidence in Western countries as well. it seems to almost be impossible to track down once in the immune system so begans to spread easly.it also says that they have developed a test to detect liver cancer in an early stage. liver cancer is caused by Hepatocellular carcinoma (HCC) it is the most primary liver cancer in theses countrys
Questions:
What is the major role of this molecule in the cell? to determine weather there is a diseas in the body or not
List three things you learned from this article in your own words.some cancers are almost unditectable, liver cancer is killing peole in asia and africa, and cancer is silent but deadly in a lot of cases.
What impact would the absence of this molecule have on the cell? it would find it right away before the cell spreads all over affecting your body

For plants on alien worlds, it isn't easy being green
link:http://space.newscientist.com/article/dn11578-for-plants-on-alien-worlds-it-isnt-easy-being-green.html
summary: The greenery on other planets may not be green. the article states Vegetation colour matters and that plants on Earth-sized planets orbiting stars somewhat brighter than the Sun may look yellow or orange, while those on planets orbiting stars much fainter than the Sun might look black. thats why some think that their is plant life out side of the solar system. Plants also absorb green light, but not as strongly, so leaves look green to the eye.
Questions: What is the chemical equation for photosynthesis?6c02 + 12h2o + lightenergy yeilds c6h12o6 +602 + 6h2o
What organelles are involved in this process? chlorophil and chloroplast
List three things you learned from this article in your own words.all plants are not green, some plants are efffected by the stars around them,and their could be plant life on a nother planet.
What impact would the absence of this process have on the biosphere? on ours nothing because this passage was about how it could be efeected in outer space

Summary: when a brittish man plans to walk or swim a 2000 kilometre journey to the North Pole as part of an attempt to draw up an accurate prediction of when the Arctic ice cap will disappear. they think the ice will completely melt away vary from 2030 to 2100.
Questions:
What are some ways this phenomenon could be stopped?N/A
Is there anything you could do to contribute to the reversal? no
List three things you learned from this article in your own words.The only way to get an gauge of the ice thickness is to take ground base,and Submarine radar can only measure ice thickness below the water line.
What impact would the continuance of these process have on the biosphere ?it may flood and it could even flood the earth

Summary:this passage was about the envintion to stop catching endagerd fish with a special net because netted hadock never swim down the net should allow clever critters to escape.
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.

Cold weather really does spread flu
Link:http://www.newscientist.com/channel/health/dn12808-cold-weather-really-does-spread-flu.html
Summary: In this article it focuses maily on how flu can be spread in differend temp. and destroyed in others,At room temperature, they found flu transmission peaks at low relative humidity (20-35%) and again at 65%. It spread less well at around 50% humidity, and not at all over 80%. This parallels the stability of flu virus in aerosol droplets at different humidities, and also the droplets’ ability to remain airborne. At over 80% humidity, droplets containing flu virus themselves fall out of the air.the animals in this article are also unique because they some times have different types of flu.The scientist also proved that the virus can be air born.
Questions: What are the symptoms of this disease? fever, ache in of the body, vomiting, running nose ,diariea, and ect
How is this disease passed from person to person? At room temperature, they found flu transmission peaks at low relative humidity (20-35%) and again at 65%. It spread less well at around 50% humidity, and not at all over 80%.
List three things you learned from this article in your own words. that flu can be spread through cold dry air, that animals don't all have the same type of flu. and how droplets can spread flu.
What impact does this disease have on the US economy? its not an endangerment its does have an effect though on the people around you because it can be spread

Darwin's take on Gray's anatomy
"My Dear Darwin, you have such a way of putting things, and write in such a captivating way. Almost thou persuadest me to have been 'a hairy quadruped, of arboreal habits, furnished with a tail and pointed ears'..." this quote is what the article is mainly about. darwin is a man that feels strongly about his religion . he has a debate between religion and evolution,he has a very opinon that he shows in his project.
How is natural selection or evolution illustrated in this article? its illustrated as a debate between a mans religion and how evolution is here are there in his project
How does this support Darwin original findings? extremely well because it even shows examples.
List three things you learned from this article in your own words. how religion and evolution debated in one mans eyes, how his letter reviled a lot for him, and i see how strongly he felt about his project.

Fungi Deployed in War on Knapweed
link: http://dsc.discovery.com/news/2006/12/28/knapweed_pla_02.html?category=earth&guid=20061228093030
The Summary: the paragraph i read about fungi was talking mainly about how some fungi helps us . The fungi was helpful in ways like finding different medications and making many medications. A scientist thought that by finding things out about fungi some of the disease that were not a easy cured could be cured with fungi.The fungus typically exists in low concentrations, but when it's cultured in a lab and sprayed in higher concentrations, it has a deadly effect.some fungi flowers that were pink and purple had a toxic effect on the land of farmers also.
Fungi Article Questions:
1) What type of lifestyle does the fungus in the article have? (Is it saprophytic, autotrophic, or parasitic?) What information lead you to this conclusion? well I'll say parasitic because it is effect in land and other things in this article
2) What benefits or problems can you foresee with this particular fungus? it is creating toxins for the soil that means its effecting the food growth.
3) List three things you learned from this article in your own words. fungi can be helpful with medicines,it can be toxic,and it is a decomposes dead organisms.
4) Infer what potential impact this fungus will have on the environment it grows in. a bad impact, because in this article it was destroying things and it was a toxin so it wasn't really helpful to us.
