Answer:
The answer is Disruptive Selection.
Explanation:
The Disruptive Selection is defined as "the situation where the selection trait is against the individual in the middle of the trait spectrum.". In the given example, there are no suitable seeds for the seedcrackers with medium sized beaks. So the criteria for the selection which is the beak size in black-bellied seedcrackers is on the different ends of the spectrum. The beaks are either small, or large. Which means that the selection trait affects the seedcrackers in the middle of the trait distribution. Therefore the answer is Disruptive Selection.
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.
