Identify the type of neuronal cell that detects bright light and provides high-resolution color vision.
alina1380 [7]

Answer:

The correct option is b. cones.

Explanation:

Cones and rods are specialized cells, called photoreceptor cells, that are found in the retina and are responsible for our vision.

Cones, allow to the human eye to have a visual acuity (ability of the eye to resolve, transmit sharp images and perceive small details in an object) and provide sensitivity to the color, are more concentrated in the central yellow spot known as the macula.

There are three different types of cones in color reception: "L cones" (sensitive to long wavelength, which is red), "M cones" (sensitive to medium wavelength, which is green) and "S cones" (sensitive to short wavelength, which is blue). Since color perception depends on the activation of these three types of nerve cells, it follows that the visible color can be determined based on three numbers called triestimulus values.

The rods are necessary for the perception of light and darkness and to adapt to night vision, because they are very sensitive to low intensity light. On the contrary, they become completely blind to bright light and, therefore, lack importance with regard to daytime vision or visual acuity.

What is the relationship between gaps and fossils?To find fossil evidence to fill the largest remaining gap in whale evolution,
Over [174]

Answer:

To find the fossil evidence to fill the largest remaining gap in whale evolution, you would search age sediment of 37MYA-46MYA.

Explanation:

Fossils are the dead remains of living organisms. The gaps between the fossils usually point out the uncertainties in the understanding of precisely how species are evolved. However, the gaps do not indicate the weakness in the theory of evolution itself. There are many gaps in the fossil records that continue to shrink with time as new fossils are discovered. The gaps are contingent features of fossil records.

Secondly, to discover the fossil evidence to fill the largest remaining gap in the evolution of whale, you would search the age sediment of 37MYA-46MYA.
