What is a source of genetic variation that involves swapping of sections of chromosomes during meiosis

1.The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.

5. Since cells are so small and can only be viewed under a microscope, it is helpful to use a model to represent the different parts and structures as related to the cell. This can be done with modeling clay, cardboard or other three-dimensional objects. Modeling clay is a very useful tool because it can be shaped and formed to look like the various cell parts and organelles. It can also be colored or painted to differentiate between cell parts. By creating a model and having the ability to visualize the parts and cell organelles, one can better understand the functioning of the cell itself. The model can also be helpful in answering specific questions about the cell such as scale of organelles, proximity to each other and appearance of various structures.

I hope that this'll help you!
