Biology - January 2007

I have seen some evolution critics state that evidence for evolution is merely adaptation. Obviously species will adapt, but at what point does adaptation become evolutionary?

Animals that eat woody plants lack an enzyme that is important in what process?
A. Dehydration synthesis of glucose monomers
B. Hydrolysis of cellulose
C. Digestion of Cellulose
D. answers A, B, and C
E. Answers B and C

i was leaning for C, because lignin (which is in wood) is hydrophobic, so i dont think an animal would eat wood for hydrolysis of cellulose... which would cut out answer D.
but im terrible at biology and my professor doesnt explain anything.

I am doing a presention on familial retinoblastoma and I can't seem to figure out why it effects the eye first. It's a gene that is present in every one of our cells but upon mutation/deletion, the tumor first shows up in the eye. I've gone through quite a few research articles & websites but I am still missing that big of info. Any help would be greatly appreciated.

I would like to know this for a project im doing.
What substance should I 'draw' in.. say on a piece of paper, so that blood would follow it?

So say that X substance, if I draw a line on the table/paper and drop a drop of blood onto that line, that blood should fill that line up without going over too much.

Thank you for the help, and ideas.
Any ideas that you give me I will try out, and if that works Ill select you as best answer.

Could it be they each carried a recessive trait for beauty and I luckily inherited both traits, from that 25% chance! I think ugliness is a dominant trait cuz almost all my family is ugly!

U- Uglyness
u- Beauty

Uu x Uu

U.: u.:
/////////////////
U.: UU // Uu
u.: Uu // uu <<<--- That's me!



BTW this was all a joke, I was just making fun of punnet squares!

... the frequency of the dominant allele?

Use the Hardy Weinberg theorem (p^2 + 2pq + q^2 =1) to solve this problem.

I don't know how to do that... help needed as soon as possible. THANKS.

Could standing in a kiddie pool filled with 95% alcohol (i.e., an alcoholic beverage that is 47 proof) get an adult drunk through osmosis?

If so, would it make a difference whether someone was up to his/her knees versus his neck in alcohol?
