No. they vary according to function.

No.
No, nuclei in cells are not all the same size. Nuclei can vary in size depending on the type of cell and its function.
No they do not. They all have the same size of cells.
No. They are all similar in size. However, larger animals do have more cells. For example, there is a big brick house and a small brick house. The bricks are all the same size but, the big brick house has more bricks.
no there are regular sizes and minis and keychains
no, if that were true we would all still be a single cell
No, all multicellular organisms have the same size cells.
All living things are made up of cells. Because they are small in size does not mean that their cell size is small. Generally cells are the same size between organisms.
All animals would be different. Animals are not meant to have cell walls; cell walls create stability. Animals have membranes instead.
The same reason all land animals breathe, to take in oxygen for cell growth and repair.
No. The total number of chromosome pairs differs by Organism.
