2.Mercury is a metal that occurs naturally at low levels in rock, soil and water throughout North Carolina. Mercury is also released into the air, water and land when fossil fuels (coal, oil and natural gas) are burned. Mercury is often found in fish. Mercury pollution is released into the air and then falls directly into water bodies or onto land, where it can be washed into waterways. When mercury gets into water, bacteria can change it into a form called methylmercury, which is absorbed by tiny aquatic organisms. When fresh water and ocean fish eat those organisms, the mercury begins to build up in their bodies. You can be exposed to methylmercury by eating contaminated fish.Methylmercury during pregnancy can impair a baby's growing brain and nervous system.The more mercury that gets into a person's body, the longer the exposure time, and the younger the person, the more severe the effects are likely to be. It also binds to a person's tissue proteins (such as muscle). Food processing, preparation and cooking techniques don’t significantly reduce the amount of mercury in fish. In my opinon the one way to avoid mercury in fish is just not eating it at all. Most studies show the way to avoid mercury found in fish is by eating fish with low mercury, but if you keep consuming fish that contains even a little the mercury  well develope one by one.There are many healthy choice for you and your unborn baby during pregnacy.

An Arbor Embolism Questions:

1. What is an embolism, as it pertains to humans?

The embolism that pertains to humans clogs the artery that stops the flow of blood from the blood vessel.
2. What is an embolism as it pertains to plants/trees?

An Embolism as it pertains to plants/trees is to have more and more gas accumulating in the plumbing system, until they can't get any water up into the leaves, when it suck water up from the ground all the way to their leaves.

 

3. What implication does this discovery have in terms of global concern?

The implication this discovery has on global concern is that droughts temperatures are rising around the globe, when drought dries out the soil, a tree has to suck harder. And that can actually be dangerous, because sucking harder increases the risk of drawing air bubbles into the tree's plumbing.

 

EXTRA CREDET

 

1. DNA is an acronym. What is DNA's "real" name?

DNA is an acronym that stands for Deoxyribonucleic acid. It is found in the nucleus of a cell. It is the genetic code for all living life forms.

2. What function does DNA serve?

DNA contains information that determines the characteristics of an organism and directs its cell activities.

3. How was DNA's shape discovered? Give me the name of three scientists who played a role in this discovery? (Hint: I'm looking for the names of two men and one woman).

the shape of DNA  was discovered by first x-ray picture, which led to the discovery of its molecular structure. it was created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. This fundamental discovery was credited by James Watson, Francis Crick and Roselind Franklin who played a large role in the reasearch.

4. DNA has nucleotide bases, what are the four bases? (Hint: C, G, T, A... what does each letter represent?)

The four nucleotides in DNA are: adenine, thymine, guanine, and cytosine.

5. In DNA, the four base nucleotides always pair up in a certain way; which letters bond with which?
Adenine pairs with thymine while guanine pairs with cytoshttp

1. What is algae? (Specifically, what kingdom does it belong to and where is it found?)

Algae belongs to the kingdom protista and it is usually found in damp places or bodies of water.

2. What is another form of biofuel that the article mentions? (Hint! “There’s more than _______ in Indiana! Indiana Beach! ")

Another form of biofuel that was mentioned in article is corn.

3. When comparing algal biofuel to the biofuel mentioned in your answer to number 2, which one allegedly produces fewer pollutants?

Comparing algal biofuel to the biofuel corn the resulting fuel, biodiesel in this case, produces significantly fewer pollutants.

4. How does the algae produce biofuel?

Special algae are grown in bulk; when fed certain sugars, they produce combustible oils that can be used as fuel additives.

a) In what way does their research contribute to the greater good?

Her research contribute to the greater good because it has made crime solving much easier than it was even a decade ago with her new research.

b) What questions did the scientist pose that led to the research that s/he did?

The question that led the scientist to pose to the research was how to figure out, how forensic experts study blood, gunpowder residues, metals and plastic debris to help solve crimes.

c) What field of science does this fall into? (Biology, chemistry, physics, etc.?)

In my opinion this field of science fall into chemistry

Criminal Codes

Dear Mahalik, Criminology appeals to me because I have always been interested in crime and criminal justice, and I have also read your article which was very interesting. The managing of criminal investigations can be a difficult task to achieve. And many of the criminology these day use technology to track down there suspect and I think your solution is another great way of helping capture the criminals. And I also want to congratulate you for all the effort you have put into this work it is really helpful for the reality of this world and keep up the good work.

Question:

These criminals knowing that the investigators use there phone to track them down and decide to not use the phone are there other technology solution to this that you might have also discovered?

1) What was the title and URL of the article you read?URlOF the artical i read from was http://www.sciencenewsforkids.org/2012/09/sleeping-people-can-be-taught-to-make-connections-between-sounds-and-smells/

2) Do you have any questions about anything you read in the article? If so, what are the questions? no.

3) What did you find MOST fascinating about the article?
The most fascinating thing i learned from this article was how we can react during sleep, despite our brain taking a break.
4) What did you learn?
i learned we inhale deeply when we smell something nice and cut there breath short while smelling the other.
5) Why was the science found in the article important, in your opinion?
 think the scientists found this important because for many years we’ve been told that sleeping was taking a break for your brain but actually it’s learning something.

6) Any additional comments?
This article was very interesting because it taught me something i haven known before
