well... you guys should try reading the entire thread... there was some pretty good things said. Phosphate is used in ATP and in phosphate backbones during DNA synthesis. Thus, phosphate is not only important, it is critical.

plants retain most of the poisons they absorb; that's why they are used to absorb toxic chemicals during the clean up of toxic wastes.

Why do you need a phosphate buffer when you run chloroplasts through a spectrophotometer to test for photosynthesis? Is it because the phosphate allows the chloroplasts to form ATP from ADP (in other words, providing the reducing agent)?

the way prions are formed and how the cause brain proteins to fold in a similar way is unknown. If you find out, you could win a noble prize. It's been a big puzzler for a while now.

Lack of vitamin A causes vision problems; dry, scaling skin Extreme deficiency causes headache, irritability, vomiting, hair loss, blurred vision, liver and bone damage not fun

lamarck's theory is never correct. a organism cannot acquire genetic traits (which are the only traits that natural selection works upon). Therefore, the organism cannot pass the acquired traits (which are not genetic) to its offspring.

use a ramp and measure the acceleration of gravity

we do not have the technology to keep astonaunts alive for the journey to Mars. First, the trip would take too long of a time with the fuels we have today. Second, it would be difficult to keep the crew from killing each other before the trip was finished (people can be that close for that long of a time before they start fighting) and we cannot properly shield astronauts from cosmic radiation. Furthermore, we have not figured out a way to successfully keep Astronauts' bone masses up. If we made a trip now.. the ship would come back with dead folks on board.

a pH lower than 0 and higher than 14 is possible. pH is caused by the natural dissociation of water. Bases and Acids change this natural dissociation by adding OH or H ions or accepting OH or H ions. As these substance bind to OH or H or give off OH or H. The OH and H molecules begin to bond more frequently or less frequently to form water. (e.g. if a substance is very acidic and creates lots of H ions, these ions would collide more frequently with OH ions and form water. Thus, the OH count is lowered while H count is increased by the substance) Therefore, it is possible for a substance to raise the OH or H count enough to go beyond 0 or 14. However, such a solution would be highly reactive and wouldn't last long in open air.

or you could just discover a way to do cold fusion har har har

if this is a creative experiment about YOUR creativity... why are you asking others for help? my idea: make thermite and demonstrate it's violent exothermic reaction.

maybe conservation efforts are anti-natural selection maybe their extinction is a part of evolution

well, the carbon dioxide and the oxygen will eventually have to be dissolved because most everything happens in an aqueous environment in life.

my answer: not long enough...

My biology professor mentioned something about specialized channels in cell membranes for water to pass into the cell. Although she (my professor) wasn't sure if the channels were only theory, she thought they were referred to as aquaporins. Do these really exist or can water diffuse throught the membrane itself?

although i am not well read in physics, i do believe that e=mc^2 does not take into account velocity or acceleration so moving something at half of the speed of light would not do anything to its mass...
