The parallel evolution of flowering plants and pollinators represents a case of coevolution. It may lead to different types of natural selection.
<h3>Disruptive, stabilizing, and directional selection</h3>
Disruptive selection is a type of natural selection that favors extreme phenotypes (in this case, flowers too small or too big).
Stabilizing selection is a type of selection that leads to decreased genetic variation (in this case, all red flowers to attract pollinators)
Finally, directional selection is a type of natural selection where an extreme phenotype can be favored (in this case, taller plants to be noted by bees).

Answer:
I believe the answer is 7
When substrate enter the active site of enzyme....the reaction starts and the substrate changes into product and detach from enzyme and so the enzyme is free for next substrate.
