Which is a part of the cell theory?

cells come from pre-existing cells

A - cells come from pre-existing cells. Cell theory is the thought that cells split from one to create a new cell. Therefore cells come from a pre-existing cell.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
