To anybody who's dissected a person before, it's your time to shine. I just need it for this art piece I'm doing.

I got a table in a bio paper:

Type of Nucleic Acid Proportion of organic bases
(percentage)
A G C T/U
Squirrel DNA 29 21 22 28
Shark DNA 28 21 21 30
Human mRNA 40 15 30 15

a) Explain why the proportion of Adenine and Guanine is approximately equal to that of Thymine and Cytosine in both pieces of DNA

b) Explain why a similer equality does not exsit between the proportion of A+G and the proportion of U+C in the RNA.

c) Despite being very different organisms, the squirrel and the shark have simelar proportions of the four different bases in their DNA. Explain how this is possible.

I am completely lost...
Please Please please help if you can! I'm really struggling!

Lets face it "Evolutionary Genetics is theoretical castles-in-the-sky, substantially disconnected from empirical reality: amorphous and ultimately not an empirical science. "Punctuated Equilbrium" Geneticist John Maynard-Smith argues that punctuated equilbrium is implausible because of it's high cost!- it slows beneficial evolution dramatically! ..... "Hit a Evolutionary geneticist in the face with a 3 lb brick..and he'll "CALL" on his compassion....Hit him in the face with the "TRUTH" and he'll "CALL" the POLICE ! ......... G'nite "kmart" shoppers and thanks for coming!

all of our eggs went up in mass after we placed them in individual beakers of isotonic, hypertonic, and hypertonic solutions. the concentration of the Isotonic is .9% NaCl and the hypertonic is a 9% of NaCl with the rest water. and the hyper is just distilled water. the whole process was done over a process of 4 days.

What are the alternatives to oxygen as far as respiration for a life form? I know all animals need oxygen. What about anaerobic bacteria? Do they need any type of gas to breathe?

Whether you answer yes or no, please include a link to verify your facts so I can read then and incorporate the facts into my knowledge.

Please no links to food industry sites, animal right organizations, the bible or wikipedia as these are all unreliable factually. Science sites are the preferred sources.

Thanks for your help and your time. :-)
