The opening and closing of ligan-gated ion channels
Disruptive selection is made of natural selection which favor both extreme phenotype and both from one extreme in directional selection. Stabilizing selection is favors the middle phenotype, average trait value over two extreme trait values.
Both the selection are disruptive selection favors phenotype while stabilizing selection favors average phenotype in population , eliminating both extreme.Disruptive selection also known as diversifying selection.
Stabilizing selection is natural selection pursue population towards the average or median . Normally environment favors average phenotype within a population.Both are two natural selection , affect the distribution of phenotype within a population,Applies to a phenotype trait.

Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Strands of hair originate in an epidermal penetration of the dermis called the hair follicle. The hair shaft is the part of the hair not anchored to the follicle, and much of this is exposed at the skin’s surface. The rest of the hair, which is anchored in the follicle, lies below the surface of the skin and is referred to as the hair root. The hair root ends deep in the dermis at the hair bulb, and includes a layer of mitotically active basal cells called the hair matrix. The hair bulb surrounds the hair papilla, which is made of connective tissue and contains blood capillaries and nerve endings from the dermis.
The answer is a microscope because itll let you see and try to identify an organism
