Blood can be three colors, red, blue, and black, right now in your body, How?

Question

Red when the cell holds oxygen, blue when its malnurisued from the lack of oxygen and black anywere else in the body, that cant be seen. We see color when light rays reflect off an object. If you put a red tomato in the refrigorator, and shut the door, the tomato is no longer red, it is black. If E=MCsquared, if we isolate light we get energy divided by mass to make light. So if i make a object that turns light into energy it will be invisible, because it wouldnt reflect the rays, it would absorb them. Right? If all mass had gravity, and all mass is composed of atoms, then gravity must be caused by atoms. Right?. Maybe its the strong force that the nucleus has that holds the atoms togeater. Though that bonding force is weak individuly, multiplied a trillions times we get gravity? Sound is the movement of molecules, pushed into our ears, if a tree falls in the woods, and no one is around, will it make a sound or will it just pushed the molecules.

Answer 2

Your discussion of color is based on perception. The tomato in the fridge is not black just because there is no light unless you perceive it that way. We see color when there is enough light to stimulate the cells in our retina that respond to the different wavelengths of light.

For e=mc^2, the c stands for the speed of light - not light itself. Light is a form of electromagnetic energy just like radio waves, x-rays, microwaves, etc.

Gravity is a little trickier to understand. It is not caused by the inter-atomic forces, however. But if you get enough atoms in one spot you could have enough mass to warp the space around that area to have a gravitational field.

Sound is the movement of a wavefront through a medium. Just because our ears are not sensitive enough to hear something doesn't mean there is no sound.

Answer 3

Color is light at a wavelength.. Large to small wavelengths are in order Red, Orange, Yellow, Green, Blue, Indigo, Violet... also, the frequency of the wave are small to Large in that order... Light emits color whether you are there to see it or not.... Blood of the red color is nothing but a reflection of the wavelength and frequency of light that coresponds to Red. Same for Blue.. it's that simple...

Answer 4

bull>>BLOOD IS RED because oxyhemoglobin is red
carbaminohemoglobin is darker red BUT STILL RED
I don't know where people get these ideas. That means That means :
venus blood is red
arterial blood is red
blood in capillaries is red
The only time blood is not red is when it completely goes through the digestive tract and becomes digested due to internal bleeding [ulsers]. It is no longer blood at this point

Answer 5

red = oxygenated
blue = deoxygenated
black = dead

no fancy explanation required.

Answer 6

It depends on where it is in the circulatory system and how much oxygen it has in it.

Answer 7

y should i answer this question when you answered it yourself!!!!!! LOL!

Answer 8

Phew! .................why didn't u let us answer that?
