I was involved in project that deals with energy drink for sports and i had added "piper sarmentosum" as they were rather rare and very nutritionous. However, I've been searching high and low for the information about this plant but couldn't seem to get much...or i can even say nothing. If anyone is doing research or even have information on this particular plant..please kindly guide me to the info ( journals, metabolites, functions, etc). PLEASE HELP...THANKS SO MUCH !!

I'm trying to get a ready for a statistics final. Please answer this question as thoroughly as possible so I can get an idea of what to do.

A physician's health study of the effectiveness of aspirin in the reduction of heart attacks over 5 years found the following: Of 11,037 male medical doctors in the United States who took one 325 mg buffered aspirin tablet every other day, 104 suffered heart attacks. Of 11,034 male medical doctors in the United States who took a placebo 189 had heart attacks. Is there evidence that the proportion having heart attacks is significantly lower for the male medical doctors in the United States who received the buffered aspirin every other day vs. those who received a placebo? Does this lead you to believe that taking one aspirin is effective in reducing the incidence of heart attacks? Explain.

Which dimension of the cylinder is more important when figuring the volume, the diameter or the length? Why?

I had a feeling it would be the diameter but I don't really know why...
(The volume of a cylinder is 3.14(r)^2 (length)

Anyone who saw this movie can think of magic being a real amazing thing. All congrats to Edison, and specially Tesla for their contribution in the creation for Energy, Power, and even magic?
My question to this, from one scene in the movie "The Prestige", Tesla, put one hand on the magicians arms, and gave a him a light bulb to hold in the other hand.. weird enough, the light turned on, and Tesla stated, " That the body can give enough energy to turn on the lamp" Is this true? If many people hold up one another, can there be enough Current to make a lamp turn on?>

"Meiosis is a two-part cell division process in organisms that sexually reproduce, which results in gametes with one half the number of chromosomes of the parent cell." I found this from another question.

So if a human diploid cell has 46 chromosomes, after meiosis I, how many chromosomes does the two daughter cells have? I know for a fact that after meiosis II, the 4 daughter cells each contain 23 chromosomes. Doesn't that mean 4 times 23 equals 92 chromosomes?

A 4-kg block sits on top of a shelf. Connected by a light and frictionless string to the 4-kg block, a 2-kg block is suspended over a pulley on the edge of the shelf. The coefficient of kinetic friction between the 4-kg block and the shelf is 0.35.
a)Find the energy dissipated by friction when the 2-kg block falls a distance y
b)Find the total mechanical energy E of the two-block system after the 2-kg block falls a distance y
c)Use your result for (b) to find the speed of either block after the 2-kg block falls 2 m

This is in relation to Kinetic and Potential Energy. I've racked up my brain all night to solve this...Help!
