I am in my early teens and my eyes are changing from blue to green. Sometimes when I look at them they're blue and other times their green. I have recently moved to Seoul, South Korea from Oklahoma, so it might have to do with the environment, or not.

I undersand that fresh skimmed milk contains carbohydrates (mostly lactose at approx 5% w/v) When fermented this is converted into other fermentation products including lactic acid (?). However does anybody know if any carbohydate remains? If so what is it? And what is the likely concentration to be? (low carbo dieters need to know!) Thanks!

Are you able to determine the kind of RNA this molecule is without any further information?
A piece of RNA has the base sequence:
U-A-C-G-A-U-U-C-G-A-A-C-A-U-G
a) Are you able to determine the kind of RNA this molecule is without any further information?

b) If you were told this piece of RNA carries the code for five amino acids, would you change your answer to part a? If so, what would your explanation be for the change?

An archaeologist finds a piece of old bone that she believes may be 2000 years old. The lab technician tells her that the carbon-14 in the bone has completed 25 percent of its first half-life. One-half life for the element carbon-14 takes 5730 years. Does this finding support her belief about the age of the bone? Why or why not?

A paleontologist unearths the remains of a Tyrannosaurus rex. We know that these dinosaurs became extinct about 65 million years ago. Therefore, would it be reasonable to expect that the carbon-14 in the fossil has completed 15000 half-lives? Why or why not? Again, one half-life for the element carbon-14 takes 5730 years.

well, it aint exactly evolution...i push my body to the max limits...and put it thru every possible harsh condtion so tht i come out stronger...and become immnue to as many things as possible.

ex: My knuckles are pretty hard..well..waaay too hard becoz of the stress i put on knuckles(by punchying and stuff..nt ppl), the calcium dposits break under stress and when they are rebuilt they are stronger and denser....therefoer my knuckles become immnue to the prior kinda stress

2) i dnt really feel pain or stuff like that if i get to focus for a few secodns...since i USED to burn myself, cutmyself and literally self destruct sumtime b4 and it seems to have helped

3)the mental stress....i exercixe my brain to the max, to teach it how to focus, concentrate, draw energy from the environment, and use its capacity to the max

The genetic code specifies the correlation between:


a. an mRNA-nucleotide sequence and a tRNA-nucleotide sequence.
b. an mRNA-nucleotide sequence and an rRNA-nucleotide sequence.
c. an RNA-nucleotide sequence and an amino-acid sequence.





please help me with this. i have a bio test tomorrow and still do not know what the answer is.

THANKS TO ALL WHO TRIED TO HELP ME!

oh yea, please briefly explain to me how you got the answer and do not forget to tell me the answer.

example: answer is b. an mRNA-nucleotide sequence and an rRNA-nucleotide sequence

i say this because sometimes people explain to me how they got the answer but never mention what the answer is.


THANK YOU!
