Summary: The article was talking about how global warming is being spead up by the rising surface ozone. As a result of this crop yeilds and plants are being killed. Since plant soil hold one- fourth of human carbon dioxide without them global warming is just spead up. Eventually there will be to much carbon - dioxide.
Questions: What are some ways this phenomenon could be stopped? stop burning forests and fossil fuels.
Is there anything you could do to contribute to the reversal. Plant more trees and start conservation groups.
List three things you learned from this article in your own words. That global warming is being spead up, that more and more carbon dioxide is filling the air, and that we should get conservation efforts going before we have a huge problem.
What impact would the continuance of these process have on the biosphere? it could change it into a non-resourcable planet with no life.

Summary:Trees in West Virginia are facing a deadly situation. If nothing is did for them then they will be moved northern, and shrink the range by half becauese of the climate. The trees dispersing their progeny to more favorable locations will eventually move.

Batrachochytrium dendrobatidis is causing many toads to be extinct. This is a deadly chtrid fungus. It has already beagan to kill many amphibans around the world, mainly in Australia, South America, and the UK.
Why is this species endangered? Because of a fungal disease.
What could prevent this organism from going extinct? They haven't found a way to control this disease at this moment.
List three things you learned from this article in your own words. I learned that frogs are seen as an important bio-indicator and it acts as an early warning system for environmental problems.
What impact would the absence of this organism have on its ecosystem/community? Climate changes can make the frogs immune systems weak, it can produce air and waterbourne pollutants such as herbicides, habitat loss, and it could make more infections.

Failing Protection Of Africa's National Parks
http://www.sciencedaily.com/releases/2007/08/070830105915.htm
The article is about the decline of big mammals like the Antelope and its habbitat. The population of these animals have gone down because of illeagal hunting or poching and poorly surveyed. Animals like these need lang to graze and live and without that they die out. Urbaniization and road construction has played a big part in the decline of wildlife.
What kind of relationship is being described in the article? The Antelopes population and its habbitat.
Describe the niche being discussed in the article. The Antilope needs grass land to graze and without that they would die.
List three things you learned from this article in your own words. That the Antelope and other animals on the planes of Africa are endagered and their grasslands. That how poorly this situation has happened.
What impact would the topic of the article have on the biosphere? It might help the animals on the Tanzania Serengeti and the habbitat survive a little longer.

HIV-TB Spreads In Africa, Undermines Control Of World's Two Deadliest Infectious Diseases
http://www.sciencedaily.com/releases/2007/11/071102084827.htm
Summary: The world-wide epidemics HIV and tuberculosis has combined to create a deadly co-epidemic that is spreading quickly in sub-Saharan Africa. Health systems cannot diagnose, treat, or contain the co-epidemic because of unanswered medical questions. One-third of the world's 40 million people with HIV/AIDS are also infected with TB.
What are the symptoms of this disease?Respiratory Problems, Lung Disease
How is this disease passed from person to person? coughing
List three things you learned from this article in your own words.
1.) South Africa is the only country in sub-Saharan Africa with a to diagnose TB.
2.) TB has dropped slightly but is still high at approximately 85 percent.
3.) The HIV epidemic has destabilized TB in regions with high rates of HIV.
What impact does this disease have on the US economy? Many people in sub-Saharan Africa are infected with it and are dying.

Genetically Engineered 'Mighty Mouse' Can Run 6 Kilometers Without Stopping, Ukyla Johnson
http://www.sciencedaily.com/releases/2007/11/071101162739.htm-
They use mainly the fatty acids for energy and produce very very small amounts of lactic acid.They also eat 60 percent more althought they remain fit, leaner, and breed longer than the wild mice in the controled group. Some female mice have children when they are only 2.5 years old. That's amazing since they don't have children after they are one year old.
What process is being used in the article?
They had over expressed the gene for enzyme phosphoenolypyruvate carboxykinases(PEPCK-C).
What is the purpose of genetic engineering in this article?
The purpose of them doing all this is to understand the metabolic and physiological function of (PEPCK-C) in skeletal muscle and adipose tissue.
List three things you learned from this article in your own words.
I learned that they were studying the rats before they expressed the gene. They found out that some of them had higher levels of that particular gene because they were more active. They also found out that they where really more aggrissive.
What impact would the absence of this process have on humanity?
We wouldn't have understood clearly why some people are able to do things for long periods of time without stopping. We wouldn't have also known that this gene is somewhat mainly the cause for it.

Sickle-cell mice cured with their own cells
Link:http://www.newscientist.com/channel/health/dn13007-sicklecell-mice-cured-with-their-own-cells.html
Summary: The article is about mice with the blood disorder Sickle-cell anaemia who were cured with stem cells, but even bigger is the fact that they retrieved the cells from the mouses tail, avoiding the ethically controversial alternative of deriving them from embryos. The problem with using this in human is they can't use viruses to ferry the reprogramming genes into cells because it may cause Cancer later in life.
Explain the phenomenon being described in the article. The phenomenon described in this article is the transformation of tissue cells into stem cells which can be used to treat diseases.
What is the difference between a genotype and a phenotype? Phenotype is physical such as eye color and genotype is the code that tells what the phenotype is such as Tt
List three things you learned from this article in your own words. Stem cells can cure some diseases, tissue cells can be turned into stem cells, their is a way to get stem cells without using embryos
What impact would the not understanding genetics have on medicine or agriculture? Without understanding genetics, genetic diseases would not be identified leaving many infants dead.
