Answer:
The Geographic barrier would have led to speciation in the finches which started from the founder effect where the finches were brought to other areas of the Galapagos. They were separated geographically so they could not mate with each other. Over time, evolution occurs through natural selection and genetic drift. This leads to the population being so different so they have reproductive barriers and can no longer interbreed. They become different species.

Hope this helps you understand better.
The limit of ecosystems to give advantages to people, that is to give biological community administrations, gets from natural cycles of water, nitrogen, carbon, and phosphorus. These procedures have now and again been altogether altered by human movement. Changes have been quicker in the second 50% of the twentieth century than at some other time in recorded mankind's history.
Answer:
Th acceptable distance of tubulin monomers along a protofilament is : <u>A. 4nm</u>
Explanation:
MICROTUBULES are an important component of the cytoskeleton of eukaryotic cells. Its function is part of a structural role that helps define cell morphology, and also serves as an intracellular motor for some proteins such as kinesin and dynein.
For the correct formation of the structures called microtubules to occur, a process called polymerization is required. In this process there is a head-to-tail junction in which the dimer junction between tubulines forms a structure called protofilaments and those protofilaments run along the microtubule. Then, the other process occurs in which, by lateral interactions between the structures mentioned above , the wall of The microtubule will be completed.
