D. is a recent development resulting from the burning fossil fuels
The human eye has three types of cone cells. These cones respond to the light and its varying signals wavelengths determines how the brain will perceive the lights signals and determine the colors the person sees.
Damage to any one of the types of cone cells doesn't cause total blindness because they have independent structure and are parallel to each other. Instead, damage to any one of the types of cone may cause COLOR BLINDNESS.
The genotypes of the parents could have been TT and Tt.
Answer: B) Circadian rhythms evolved in a common ancestor to life and is present in all life forms.
The circadian rhythms comes to play because of the evolution of different pathways and molecular mechanisms over the time in different species in relations to its environment and varying changes.
Explanation:
Circadian clocks are believed to have evolved in parallel with the geological history of the earth, and have since been fine-tuned under selection pressures imposed by cyclic factors in the environment.
Evolution has selected a system of two intertwined cell cycles: the cell division cycle (CDC) and the daily (circadian) biological clock. The circadian clock keeps track of solar time and programs biological processes to occur at environmentally appropriate times. One of these processes is the CDC, which is often gated by the circadian clock.
