Answer:
The correct answer is C) gene flow
Explanation:
The biological species concept defines what is a species. It says that a species is a group of individuals in a population that interbreed with each other. So there should be gene flow between the members of the population to come under species.
Appearance does not define that two individual are of same species because even different species can look same for example Western meadowlarks and eastern meadowlarks looks identical to each other but they do not interbreed so there is no gene flow between them so they are not same species.
Therefore the primary criteria for determining species boundaries is gene flow.

B. Cell wall and a central vacuole
The cell wall is a rigid structure that surrounds the cells and allows plants to stay upright. Animal cells are more fluid.
The central vacuole is a large region in the cell that stores nutrients and fluids. Many cells, including animal cells, contain vacuoles, but most are small, and only plant cells contain large central vacuoles.
Hope this helps!!

which they have the role of dividing the plant’s cell and in the same way this
is where the growth is being done.
