The metabolic pathways of organisms living today evolved over a long period of time---undoubtedly in a stepwise fashion because of their complexity. Here are the pathways to put in order: Krebs Cycle, Electron Transport, Glycolysis, and Photosynthesis.

My husband is an identical twin and tonight our son who is only 5 stumped me with a question while we were talking. He asked if identical twins have the same fingerprints? I really do not know the answer and my husband is at work so I can't ask him. Anyone know? My guess would be no, but am not sure about identicals.

1.
The speed of quantum of light is absolute quantity c=1.
But why does everyone say that there is no absolute
speed of motion?
2.
The speed of quantum of light is absolute only in
Vacuum, in absolute Vacuum.
But why does everyone say that there is no
absolute reference system?

alllllrighty. so if i have a substitution problem like this:
4x+3y=13
{
x+y=4

OR this...

y=5-x
{
1=4x+3y

how do i solve it??? can ya'll please explain how to solve these?? i would appreciate it so much!!!! and it'd save me the stupid speech about my math grade lol.... THANK You thank you thank you

Can some one plz help me figure out this question, I really dont understand how to do it.

A particle moves along the x-axis so that its velocity at any time 't' greater than or equal to zero is given by..... v(t)=3t^2-2t-1.
The position x(t) is 5 for t=2

Find the total distance traveled by the particle from time t=0 until time t=3.

Thank you very much for your help, I really appreciate it!

This was originally in response to a question about telekinesis, but I began to wonder what others thought of my theory.

Its all a matter of going beyond what the human consciousness is aware of.
Similar to my theory of walking through walls and other porous objects:
Everything is made up of molecules and atoms. Subconciously your mind controls the atoms and molecules that form you. If you can somehow manage to use that part of your mind consciously you'd be able to manipulate yourself to fit through the porous object and then resume your form on the other side.

However for the sake of telekinesis you'd have to take into account the distance and how much of your structure you can manipulate to extend and move something. While some may say this technically isn't telekinesis it would be very similar.
