Biology - March 2007

its between tourettes and thyroid disease. the thing is, we have to choose something that "runs" in the family. hyperthyroidism runs in my family. i was thinking about doing it but i dont really like the topic because there isnt really much information that suggests it can be inherited.

tourettes does not run in my family but i can still do that topic. i chose to do this since i know that it can be inherited but they havent found the gene that is responsible for this disease and also in hyperthyroidism. i like tourette because it is interesting what these people with the disease have to go through.

which do u think is the better one to do?

I am not a creationist but I do agree that there are so many things Evolution does not seem to explain, such as...

From a recent question (in Food) about lack of fresh-caught northwestern Atlantic shrimp at my local supermarkets I learned among other things that this species, pandalus borealis, is found in scattered ("patchy" was the word used in one report on the Internet written for Canadian Government Fisheries) and non-contiguous and not migratory to each other populations located hundreds of kilometres from each other from south of Maine to the Arctic. Under evolutionary theory, like Darwin's differing finches on different Galapagos islands, should not the differing and separated shrimp populations evolved into different species? Why didn't they. How common is this (species that were broken up geographically millions of years ago that remain the same species in the separated populations)?

It's scientifically proven that information, any information cannot result from random processes.

So where did the information contained in our DNA come from?

I would like to know two mutualistic relationships (both benifit) that involve plants.
If you could mention a few examples, that'd be great.

Strength is one characteristic of matter, and the strength is determined by the bonding associated with each element or molecule. Diamonds, the hardest of substances, and graphite, one of the weakest, are both composed of carbon. What force or bond is associated with each?

You are interested in understanding how the brain works, and are using the fruit fly Drosphila as a model system to study brain development. You perform microarray analysis to try to determine genes expressed in the fly brain. For your microarray experiment, you first prepare cDNA from fly brains and label it with a red fluorchrome. Then you isolate cDNA from whole flies and label it with a green fluorchrome. Next you hybridize these cDNA populations to a microarray containing the Drosphila genes. From this, you obtain a list of genes that are specifically enriched in the brain. (those that show up as a red spot on the microarray). You are dissappointed bc your favorite fly gene, tubby, does not appear on this list, even though you have repeated the miroarray experiment 10 times and did not encounter any technical difficulties. The reason you thought tubby would appear on this list is that you believe tubby is important for brain development, since flies mutant in tubby have no brains.

Im sorry that this question seems crude, but I was told that material moves through the digestive system through peristalsis, which makes sense for solid and liquid matter, but I don't understand how gas can travel through the extremely long intestinal system, and relatively fast at that, to come out as flatulence.
