Answer:
Allopatric speciation occurs due to the geographical isolation between individuals of the same species. The geographical isolation can be due to canyon development, mountain formation, migration, etc.
The geographical isolation gives different environmental condition to the separated population of same species to live which allow these two population to evolve differently and evolve in different species.
So when two population becomes different species and not able to interbreed with each other when give opportunity then the allopatric speciation between the two populations becomes complete.
Answer: Plant Cell
Explanation: Since I cant see in your question about what structure is about I have found that it might be the plant structure and I hope that this would help. I will also post you a picture of it.
A is Vacuole
B is Chloroplast
C is Cell membrane
D is Golgi bodies
E is Smooth and rough endoplasmic reticulum
F is Cell wall
This structure is a plant cell structure and it has a cell wall and plasma membrane.
Also, it has vacuoles in the center that are taking much space since they are huge.
Since it is a plant cell it has a chlorophyll and with it organelles and both of them are called chloroplasts.
Chlorophyll is giving the plant cell a green color. This kind of cell is a basic and the most important for the Plantae kingdom organisms.
the region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division.

The hydrogen bonding that created its hexagonal shape....the molecules get closer together and there will be more hydrogen bonding making it solid
200,000 is the population density.
