What could prevent this organism from going extinct?Emerging the parisites

List three things you learned from this article in your own words.Pnadas are bout to be instict, There are only 24 left in the wild, A worm is the cause

Summary:Wild giant pandas are now becoming extinct because of parasitic worms. In 2004-2005, 24 pandas were found dead, half of them showed symptoms of viseral larval migrans. Pandas all over the world are dying because of some little worm and ther is not a diagnose for them.

Gregor Mendel was very dedicated to his work. He was a monk but on his spare time he worked with plants which led him to genetics. Today he is called the father of genetics. He studied the inheretance of traits in plants.

Mendel and Genetics
Explain the phenomenon being described in the article.talks about Gregor Mendel
What is the difference between a genotype and a phenotype?geno is letters, pheno is looks
List three things you learned from this article in your own words.Gregor was a monk, he loved plants, he was dedicated to his work
What impact would the not understanding genetics have on medicine or agriculture?we wouldn't know our blood types, we wouldn't know how to cure the flu and other diseases or viruses

Natural Selection works in wierd ways. It changes an animal according to their environment, what they eat, and what dangers they face. The piranha was changed according to their environment. They changed in order to survive.

Natural selection/Evolution
How is natural selection or evolution illustrated in this article?the piranha was changed to live in its environment
How does this support Darwin's original findings?it matches it
List three things you learned from this article in your own words.piranhas didn't always live in South America, they weren't always the same, they changed their DNA
What impact would the absence of this organism have on the ecosystem?the rivers of South America ould be polluted with dead bodies

MRSA Infections on the Rise, But Treatable If Caught Early

Link: http://healthlink.mcw.edu/article/1031002819.html



Summary: This article discuss' methicillin-resistant Staphylococcus aureus or MRSA. The article states that the disease was first identified in the early 1960's, and first began infecting humans in the mid 1970s. The article also describes how their are more than one type of MRSA.

HA MRSA (Hospital Aquired Methicillin-Resistant Staphylococcus Aureus) and CA MRSA (Community-Associated Methicillin-Resistant Staph Infection). CA MRSA attacks and destorys the white blood cells in our body that help us fight infections.



Questions:

What are the symptoms of this disease? Common symptoms include an inflamed skin infection that may be mistaken for a spider bite, but once inside the blood stream MRSA can cause septicemia (blood poisoning) or endocarditis (an inflammation of the lining of the heart).

How is this disease passed from person to person? This disease is passed through
Close skin-to-skin contact, Openings in the skin such as cuts or abrasions, Contaminated items and surfaces, Crowded living conditions, Poor hygiene.

List three things you learned from this article in your own words. I learned that MRSA is not something new, there are 2 different types of MRSA, and the flu kills twice as many people then MRSA

What impact does this disease have on the US economy? This disease could cause an epidemic which would speed up the need for a wide spread vaccination.

Cell Organelles are what keep the cell functioning. They control functions vital for the cell's survival. They keep your cell moving. Organnelles would include: nuecleus, ER, Golgi Apparatus, ribosome, chlorolplast, and more! I'm now going to answer questions about the nucleus.

Cell Organelles
What is the major function of this cell's organelle?controls the cells
Which cell types have this organelle?all
List three things you learned from this article in your own words.Nucleus is important to cell, it controls it, it is the brain
What impact would the absence of this organelle have on the cell?cells would die
