How do living organisms produce electricity?

Is it possible that our planet Earth is the only place in the universe where intelligent life exists. Since our modern technology hasn't?
Best answer: With the enormity of the Universe it could take a 100 years a 1000 years or a million years to detect a signal from another intelligent lifeform in the Universe.
As time goes by we will develop better and better technology in order to search for intelligent life but as I said above this is likely to be a long way off. 
How can evolutionists be so sure of things that happened millions of years ago?
Best answer: they would rather believe men OVER GOD... 
If the x in x(2219) is tripled, how much will the expression change?
Best answer: x (2219) = 3x This is the "old" value
3x(2219) = 9x This is the "new" value
It's a matter of the wording:
The new value has changed to 3 times the old value (which is what you are taking as the answer).
However the amount the expression has changed is the difference between the new value and the old value (which is what the books says). or...
9x  3x = 6x
Testing:
if x = 2 then the old value is 2 * 3 = 6;
Then the new value is 6 * 3 = 18
but the difference is 18  6 = 12 = 6 * 2 ( 6 times the old value of x) 
Is there a simple way to find square root in mathematics?
If not, what is the easiest way? Make the formula understandable, lol. I usually keep formulas on a postit on my desk, so if the formula is clearly expressed I can use the formula easily and memorize it.

How can I get an acquired immunity to pathogens? How does it happen?

How do I know if I am evolving into Gorilla like species?
Best answer: Gorillas cannot speak  their throats are anatomically wrong and their brains are missing certain necessary parts. Strength means nothing  if you can learn a language and talk, you're a human, you'll ALWAYS be a human, individuals do not evolve, only populations evolve, over generations.... 
(2x − 3) (x + 4) = 0 solution?

Find a if u · v = 20, u = (a, −2, −1), v = (a, 0, 5).?

Find the sum of 3 roots of eqn x^3+4x^2+x6=0?
Best answer: x^3 + 4x^2 + x  6= 0
(x  1) (x + 2) (x + 3) = 0
The sum of 3 roots:
3  2 + 1 = 4 
How to show the sum_(n=1) ^ infinity 1/2^n =1 algebraically?
Best answer: S = [n = 1→∞]∑(1/2ⁿ) = 1/2 + 1/4 + 1/8 + ...
2S = 1 + 1/2 + 1/4 + 1/8 + ...
2S  S = (1 + 1/2 + 1/4 + 1/8 + ...)  (1/2 + 1/4 + 1/8 + ...)
S = 1 + (1/2  1/2) + (1/4  1/4) + (1/8  1/8) + ...
S = 1
so [n = 1→∞]∑(1/2ⁿ) = 1 
True or False: Evolutionists cannot point to even one definitive example of an organism that has changed from one kind to another.?
