Question

What is the function of the central nervous system?

to gather information
to respond to glands and muscles
to receive stimuli from the environment
to process information and form a response

Answer 1

D to process information and form a response

Answer 2

yup

Answer 3

Which type of muscle decreases the size of the pupils of your eyes in bright light?

skeletal muscles
smooth muscles
cardiac muscles
both skeletal and cardiac muscle

Answer 4

smooth muscles

Answer 5

um i truely think that it is the optiplex muscles but tht may be rong

Answer 6

nope its smooth.. lol

Answer 7

Smooth muscle. Smooth muscle is the only muscle tissue, outside of the cardiac tissue in the heart, that is involuntary. The contraction of your eye's pupil to light is not voluntary.

Answer 8

yup shes right.

Answer 9

but shes talking abought the eye

Answer 10

o shut up i know that girls are smarter than boys

Answer 11

LOL

Answer 12

by alot:D lol

Answer 13

omg you two

Answer 14

ok if your so smart what is e=mc2

Answer 15

i just know how to use the internet.... E = MC ^ 2 is perhaps the most famous equation of all time. It stands for E(negery) = Mass times the Speed of Light (C) squared. What this means is that if you take the mass of an object and multiply it by the speed of light (2.9 x 10^8 metres per second) you will then have calculated the ammount of energy. As you can see, even a tiny ammount of mass when multiplied by such a huge number (C) yeilds an incredible ammount of energy. Releasing that energy can do everything from power cities (a nuclear powerplant) to destroy them (a nuclear bomb). Further applications found in science fiction include Star Trek's famous warp drive technology that uses a matter/anti-matter reactor to release the energy of particles to power an entire space ship

Answer 21

This is a very complex subject. I guess the easiest way to paraphrase it is to state that there is no such thing as an absolute position or speed or momentum in the universe. That means that when you ask questions about these things, you have to ask "compared to what?" This results in some pretty non-intuitive observations.

For example, in Special Relativity, we learn that the speed of light is a constant, regardless of the speed of the source or the observer. This means that if you measure the speed of a light beam from a star that is receding from you at .99 x the speed of light, that light will still pass you at exactly the speed of light. The same is true if you are departing or approaching a star - that way noone can tell whether you are moving or the star is moving, because there is no fixed or favored frame of reference. This in turn does things like affecting the passage of time in frames of reference that are moving at high speeds relative to each other, etc.

In General Relativity, the same principle is applied to things like gravity. We find that gravity is not really a force, although it acts like one. It is a warping of space-time (sorry for the buzzwords) in a way that changes what we think of as straight-line motion through space into a curved path oriented toward objects with mass. The force must be applied to keep us from falling in that direction; the falling is caused by gravity.

There's about a lifetime or so of work wrapped up in these two paragraphs, but it's a synopsis.


ADDED: The speed of each of the two light beams passing each other in opposite directions will still be exactly the same speed of light - regardless of where you are measuring it from. You could not travel on one light beam to measure the other one, because you cannot reach that speed - but you could theoretically reach .99 x that speed in the same direction. If you did, you would measure the speed of the light beam traveling in the opposite direction as exactly the same speed of light - relative to you.

Speed and geometry and time are all relative - not fixed. If you are traveling past me at a high speed, I will measure your length as shorter, your time as longer, and your mass as higher than you will. Neither of us is wrong. It is how the universe works.

The speed of light from distant stars has been measured very precisely. It is always the same - whether we are on one side of our orbit moving toward the star, or the other side moving away. Whether the star is moving toward or away from us - still the same. We can tell that we are moving toward or away from the star by Doppler shift, but the speed of the light as it passes us is always exactly c. Not terribly intuitive, but if it didn't work that way, the universe would suddenly be a very strange place - so it was a brilliant series of ideas by a brilliant person.
