The distinction between the sensation and perception allows the researchers to distinguish between the information processed by the receptors versus the information processed in the cortex.
<u>Explanation</u>:
The sensation is a process by which the sensory receptors take up the signals or stimuli from its surroundings and send it to the brain through nerves. Whereas, in the process of perception the brain organizes, combines and makes patterns from the given stimuli and gives the response to the particular stimuli accordingly.

Answer 1: Difference b/w wet and dry earwax genes is due to switch of a single DNA unit i.e. single nucleotide polymorphism.
Answer 2: Earwax is important in many ways mainly it is a biological flypaper as it prevents dust and insects from entering the ear.
Answer 3: Genetics have proved that for those who sweat a lot and have armpit odor have wet earwax.
Answer 4: The wet type earwax is dominant one with honey brown or dark brown color while dry one is recessive.
Answer 5: As wet earwax is dominant trait, according to the given scenario the genotype of parent with wet earwax will be "WW" which when crossed with dry earwax parent will have all the offsprings with wet earwax.
