Explain the role rods and cones play in vision.

Answers

Answer 1
Answer:

Answer:

The cones detect the brightness and the rods the colors.

Explanation:

Thanks to a layer of photoreceptors inside the eye, it is able to convert the captured light into brain signals.

There are two types of photoreceptors: rods and cones.

  • Rods: they allow the human eye to have a visual acuity (the eye's ability to resolve and perceive small details in an object) and to differentiate colors.
  • Cones: are in charge of detecting the intensity of the light. They are very numerous and are very sensitive. Not being able to distinguish colors, they give rise to an achromatic vision.
Answer 2
Answer: rods work very well in darkness/ low light. Cones process colors.

Running wather and groundewater:What are five factors that determine the velocity of a stream?

Answers

Explanation:

The gradient of slope – the steeper the gradient the higher the velocity

the shape of river channel – the more straight the channel (with fewer meanders) the higher the velocity

The volume of water that the river carries – The more water the higher the velocity because more water has more mass that carries more momentum.

The roughness of the substrate or stream bottom – The rougher the river bed is, the slower the river water velocity due to increased turbulence and less laminar flow

The depth & width of the stream – The narrower and deeper the river channel the higher the velocity. This is because the water has a lesser surface area to rub against the river bed as it flows hence gains higher speeds due to lower friction.
