Answer:
The best answer to the question: The Z disc forms the end____ of a sarcomere, would be: the end border, or the point where sarcomeres join, within a muscle fiber.
Explanation:
Concretely, a Z disc is the boundary line that divides sarcomeres within a muscle fiber. They are the bordes between sarcomeres and they contain the most important molecule, actin, which forms the thin filaments essential for muscle tissue movement. This actin molecule, present along the Z discs, under the correct stimulation and circumstances, will bind to myosin and thus movement will be possible.
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
