How does a toad's eyes work?

Their eyes work similarly to those of other vertebrates, including ourselves. However, in addition to their cones and rods, toads have a special type of sensitive cells in their retina called "green rods". They are able to perceive a wide range of colors, because the green rods are sensitive to short wavelengths (blue).

they are called phosphenes.\nit's caused by mechanical stimulation of the photoreceptors in your retina.

The animals originally want to eat the toads and frogs, but alot of toads and frogs secrete a distasteful fluid from their skins when threatened. The animals then decide not to eat them and leave them on the ground. That's why there are so many dead frogs than other animals being left to die.

Each of the eyes are slightly recessed, and each eye points in a slightly different direction.  This makes it so that depending on which eye detects the most light, the insect is able to determine the direction of the light.  Humans, by contrast, find the location of light by having a lens which focuses the incoming light on the photo-sensitive retina at the back of the eye.

It's due to the way in which your eyes percieve light. Focus is determined by a point of reference. If your friend that you are looking at is the point of reference, they will appear as if they are not moving.\n\nThis is similar to when it looks, in a car, as if you are going backwards when the truck next to you starts moving forward.

In fact, the optic nerves would still likely function, and the blood on theeyeball woudl *not* block vision-only perhaps make it pinkish.  THe strain on the optic nerve might cause severe pain and/or light flashes.\nAssuming that the eyes worked perfectly (which anyway is fairly likely), they would see an process whatever they were looking at-so yes, your eyes would see each other, andyour brain would process that as it would normall-If you have ever looked through a small hole with just one eye-say, a microscope, then your eyes were getting completely different views...you can think of many times when your eyes were focused on totally different things, and yet your brain didn't get scrambled or confused...it went with the view that *you* were interested in- The brain will make dominant the view from the eye that you are focused on-so, if you are looking through a microscope, you see (with the micro eye) a slide of a leaf-but with the other eye you see the side of the microscope and the table- YOur brain brings the leaf side to the top, and enhances it over the other, because it is what you are interested in.  If you took your eyes out and faced them to each other, you would get two views of eyeballs-your brain wouldnt scramble or freak, it would just switch dominant views based on you attention at that second.\n\nAnd I absolutely guarantee the optic nerve would NOT seperate from the eye itself- I've had to dissect these before and they are attached extremely well- I have also had the misfortune of being with a guy who had the orbit of his eye broken, and his eyeball bulged out-he could see with it fine, though it hurt horribly, and once the eye was put back in , there was no permanent damage

1- it helps because the frog's head enters a new environment first, and thus can detect any potential hazards before the rest of the body is exposed.\n\n2- the saliva is very sticky and it had papillae that increase the surface area of the tongue so the bug sticks better.\n\n3- \nhttp://www.lookd.com/frogs/frog3.jpg\nhttp://universe-review.ca/I10-82-frog.jpg\nhttp://darwin.baruch.cuny.edu/gelfond/Bio1005/class-2-frog.htm\n\n4- \n1) respiratory system includes lungs to allow it to breathe on ground.\n2) its skin is adapted to avoid dehydration when out of the water.\n3)Legs allow it to walk and hunt on land.\n\n5- \n1) respiratory system includes gills that allows it to absorb oxigen from water\n2) smooth skin allows for smooth glide-like swimming in water\n3) dactilia are webbed on both hands and feet which allow for powerful rowing when swimming.\n\nCheers.

A dog (usually) has 2 eyes, 4 feet, and 1 tail.

Red eye occurs when the level of the flash is at the exact same level/angle of the subjects eyes(retinas). It's the light from the camera bouncing off the back of the eyes and reflecting back into the camera's lense. Anyone in a picture can come out with red eye.

Our eye colour is basically determined by the combination of colour \npigments on our iris (i.e. the ring of muscle that control the diameter of \nour pupil, which is controlled by reflex involving the mid-brain). In \nessence, there is a pigment called melanin that gives rise to colour in \nthe hair, the skin and the iris and the choroids layer of the eyes. \nMelanin is contained within special cells called melanophores, and is \nproduced by the metabolism of the amino acid tyrosine. There are a number \nof different type of melanins, and different combination of the different \nmelanins give rise to the difference in our eye colours.

This article gives a good description of all the parts, their purpose, and some diagrams. That should be great for your report.\nhttp://en.wikipedia.org/wiki/Eye#Anatomy

>>>What happens when the air is pumped into the lungs? \n\nThe lungs expand.\n\n>>Compare the walls of the atria and the ventricle?\n\nThe atria walls are thin and flexible. The ventricle wall is  thick and more rigid.\n\n>>>Describe the movement of the leg muscles as the leg is bent and straightened.\n\nWhen the leg is straightened the muscle on the opposite side of the joint expands. You really do need some detailed digrams or a frog carcasse to explain this properly.\n\n>>>>How is the location of the nares an adaptation to living water? \n\nThe nares are located high on the snout and towards the front. That allows the frog to breathe while keeping almost all of its body beneath the atwer line. \n\n>>>How does the length of the small intestine relate to its function in absorbing digested food?\n\nThe longer the intestine the more time food has to digest and the more thorough digestion will be.\n\n>>>Explain why the frogs hearts has a thicker wall than the atrium.\n\n\nHuh? The atrium is part of the heart. Part of the heart can't have a thicker wall than the heart.

Depends on which ones.  Some are phosphenes--they're made more visible by pressing on the eyeball, but that can be harmful to the eyeball--do NOT do it!  Others are simply afterimages--artefacts of how the eyes process incident light before sending the signal to the brain.

The pupil is a circular opening that opens and closes according to how much light it's being exposed to. If too much light is let in you can't see anything at all. I suspect that cats have different shaped pupils because their eyes are designed to be able to see in almost ZERO light.
