"Cones provide about<u> 90%</u> of the visual input to the brain.

<h3>What is cones?</h3>

Cones are one of the two types of photoreceptors in the retina, the other being rods. Cones are responsible for color vision and high visual acuity. They are most concentrated in the fovea, the central region of the retina, where the visual stimuli are most focused.

Cones have different types of pigments that respond to different wavelengths of light, corresponding to the colors red, green, and blue. The signals from the cones are processed by the bipolar cells, ganglion cells, and the lateral geniculate nucleus, before reaching the primary visual cortex in the occipital lobe of the brain.

Cones account for about 90% of the visual input to the brain, because they are more numerous than rods and they have more connections to the ganglion cells, which transmit the information to the brain.

Rods, on the other hand, provide about 10% of the visual input to the brain. Rods are more sensitive to low light levels and are responsible for night vision and peripheral vision.

They are more distributed in the periphery of the retina, where the visual stimuli are less focused. Rods have only one type of pigment that responds to a broad range of wavelengths, resulting in low color discrimination and low visual acuity.

The signals from the rods are processed by the same pathway as the cones, but they have less connections to the ganglion cells, and therefore less influence on the visual input to the brain."

Therefore the percentage that filled the gap is 90%.

Cones provide about <u>90%</u> of the visual input to the brain.

what are cone cells?

Cones are a type of photoreceptor cell in retina. They gives us our color vision.

  • Cones are concentrated in center of our retina in an area called the macula and help us see fine details.
  • Retina has 120 million rods and 6 million cones.

They are part of the eye responsible for converting the light that enters your eye into electrical signals that can be decoded by the vision-processing center of the brain.

Cones are responsible for the color vision.

Dafna1 [17]

Answer:

the Earth is tilted on its axis

the Earth is a sphere

different materials on Earth's surface absorb heat at different rates

Explanation:

The heating and cooling rates of land and water differ. This effects the heating of the earth according to these substances. Since the planet Earth is spherical in shape, the equator heats up more as compared to that of the polar regions. The differences in the seasons is because of the axis on which the Earth is tilted. Because of rotation, the heating and cooling of the Earth's surface differ. These are the reasons that are the reason for the uneven heating of the sun.
