How many colors do butterfly see?
Quote from the related link: "Butterflies can see red, green, and yellow, but they also see color in the ultraviolet range, which reveals patterns on flowers-and other butterflies-that we can't see."
How has the microscope helped humans?
It helped humans see small things.
What is a natural variation in a population?
Look at a population of humans. Your class will do. Now, how many different heights, hair colors and other assorted phenotypic variations can you see in this small population?This is the frequency of alleles of these types that we call natural variation.
Do dogs have peripheral vision?
The human eye sees because there is an array of receptor cells called rods and cones at the back of the retina. Rod are comprised of one neuron connected to an array of receptors. As such, rods are very sensitive to motion and the existence of light, but don't perceive colors. Cones, on the other hand, are one neuron per receptor, and it's with cones that we perceive colors. There are three kinds of cones in human eyes that correspond to the colors red blue and green. Humans, then, are trichromats; our color vision is based on three colors of light and their various combinations. Cones don't pick up light or motion as well as rods, but they do perceive color. This is why the stars look appear to be white to us: they produce enough light to activate our rods, but not enough to activate our cones, so we don't see the colors that are there.Dogs have very few cones, but a plentitude of rods. This means that dogs see light and motion very well, but don't perceive color as well as humans. Unlike humans, the cones dogs have detect only two colors: blue-violet and yellow. They have a hard time distinguishing red from grey. So dogs see better in low light situations, but don't pick up all the colors humans do.Also, dogs' eyes are generally more spread out than humans', so they see as much as 270 degrees around them, as opposed to humans which get only 180 degrees. But the human field of vision overlaps more, so we get better depth perception than dogs, and our long distance vision is better. Human normal sight is measured at 20/20. Most canine breeds, however, don't see much better than 20/70 (I exclude Labradors, which get very close to 20/20).Also, dogs have a reflective structure in the back of their eyes that we think reflects light back through the retina, so their low-light vision is even better.Dogs can see in much dimmer light than humans. This is because the central portion of a dog's retina is composed primarily of rod cells that "see" in shades of gray while human central retinas have primarily cone cells that perceive color. The rods need much less light to function than cones do.Dogs can detect motion better than humans can.Dogs can see flickering light better than humans. The only significance to this appears to be that dogs may see television as a series of moving frames rather than as a continuous scene.Dogs do not have the ability to focus as well on the shape of objects (their visual acuity is lower). An object a human can see clearly may appear to be blurred to a dog looking at it from the same distance. A rough estimate is that dogs have about 20/75 vision. This means that they can see at 20 feet what a normal human could see clearly at 75 feet.Dogs are said to have dichromatic vision -- they can see only part of the range of colors in the visual spectrum of light wavelengths. Humans have trichomatic vision, meaning that they can see the whole spectrum. Dogs probably lack the ability to see the range of colors from green to red. This means that they see in shades of yellow and blue primarily, if the theory is correct. Since it is impossible to ask them, it is not possible to say that they see these colors in the same hues that a human would. Whether or not the ability to see some color is important to dogs or not is hard to say.Read more: Vision - How dogs see
Are conkers poisonous for humans?
Well you see some people say they are, some say they aren't. In my opinion, conkers are NOT poisonous to humans.
Do bunnies see colors like humans do?
No. Research indicates that they do have some ability to distinguish between different colors (specifically between blue and green), but they do not see colors "the same way humans do"... except, possibly, for humans with certain kinds of color blindness.
is there a color we cannot see but exists?
Humans can see around a million colors. There are more than 100 million colors.
What colors can a Chickadee see?
They can see all the colors you can see, plus a little into the ultraviolet spectrum.
Are Crickets color blind?
Indeed they are color blind, they cannot see colors that humans can see. But they can see the ultraviolet rays of the sun, that us humans can see.
Howbettter can bees see than humans?
Bees can see higher frequencies of electromagnetic waves than humans can. Bees see flowers in different colors then we do. Bees see color about triple the speed as humans do.
Do you all see the same colors?
All humans see the same colors if normal. It depends on the interpretation of light of different frequencies by one's brain.
Are harvester ants color blind?
Ants are not color blind. They may not be able to see colors as sharply as humans, but see the colors of objects.
How do wasps see humans?
Wasps cannot see the color red. But see much the same colors we do.
Do cats see all the colors you humans do?
no, they see the same colors as us humans seeWell, not in the sense like most people would think. They can see spirits, and they can see colors that most humans don't look for or can't see, like energy. It's not very scientific, but it's true.
Can cats see that people can't see?
no, they see the same colors as us humans seeWell, not in the sense like most people would think. They can see spirits, and they can see colors that most humans don't look for or can't see, like energy. It's not very scientific, but it's true.
How do humans see colors in wavelengths?
Most humans eyes are sensitive to wavelengths between about 400 nanometers and 700 nanometers
Why do graphs help explain why humans cannot see colors that fall in the ultraviolet or infrared part of the electromagnetic spectrum?
Because we can't see the colors on the spectrum so we have to use a graphto show the colors.
