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.
Ketogenesis is the conversion of acetyl CoA into Ketone bodies. CoA stands for fatty acid fragments, not whole fat. The fat moelcule is first broken into fatty acids and then the ketogenesis process takes place. The conversion of acetyl CoA into ketone bodies happens whenever acetylCoA cannot be oxidized.
