Answer:
A-Band
Explanation:
Sarcomere is the basic unit of skeletal muscle and shows various striations under the microscope.
Anisotropic band or A-Band is the portion of sarcomere that contains both the thick and thin filaments . A-Band appaers dark under the microscope. Thick filaments are consist of actin and thin filaments consists of myosin.
I-Band contains only thin filaments of myosin. H- zone contains only thick filaments and no thin filament. Sarcomere is the unit of a skeletal muscle. Synapse is the junction between two neurons.
Thus, the correct answer is option (A).
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.
