In my science class we are doing a panel discussion on evolution in a week. I have been assigned to the pro-evolution side (even though I am con-evolution), and I need strong arguments that are pro-evolution. I have already checked out the book that has all of Charles Darwin's essays, etc. in it. What I need are strong, reliable, logical sites with pro-evolution facts on it. All information is appreciated, but please do not give your own opinions or information, I need something from a very reliable source. All answers are appreciated, but PLEASE do not bombard me with answers like "what do you mean your con-evolution", "You're completely ignoring the facts" and "Do your own homework, kid", etc. I am doing my own homework, I just might need some extra help and somewhere to start.

Thank you!

H2O2 ==> H2O + O2

Na + H20 ==> NaOH + H2

C2H6 + O ==> CO2 + H2O

Mg(NO3)2 + K3PO4 ==> Mg3(PO4)2 + KNO3

can you guys go to google earth and type (Venice, Italy) and awnser this question.
If global warming is a real problem, as many scientists and world leaders state, what appears to be Venice’s problem based on what you see in the map? AND assuming that this “problem” is inevitable, use what you see in the map and describe something that the Italian government can do to avoid or minimize the effects of this “problem

THANKS>>>

Swimmer in River

--------------------------------------------------------------------------------
A river 700 ft wide flows with a speed of 10 ft/s with respect to the earth. A woman swims with a speed of 5 ft/s with respect to the water.
--------------------------------------------------------------------------------
a) If the woman heads directly across the river, how far downstream is she swept when she reaches the opposite bank?
d1 = ft *
1400 OK

HELP: Can you find the time it takes the swimmer to get across the river?
HELP: Can you use this time to find the distance down river she was pulled?


--------------------------------------------------------------------------------
b) If she wants to be swept a smaller distance downstream, she heads a bit upstream. Suppose she orients her body in the water at an angle of 37° upstream (where 0° means heading straight accross, as in part (a)), how far downstream is she swept before reaching the opposite bank?
d2 = ft


--------------------------------------------------------------------------------
c) For the conditions of part (b), how long does it take for her to reach the opposite bank?
t = s

The acceleration of gravity is 9.81 m/s^2.

A) Find μs between the clock and the floor.
B) Find μk between the clock and the floor.
