Quick cells are not large as a cube. explain why in terms of a cell's surface area-to-volume ratio.
also my second question is how is the structure of a unicellular organism different from a multicellular organism how does this affect function
did you see my comment below

According to theories of how life began, how did early organic molecules begin to separate from the outside world? a: specialized enzymes were required b: chains of amino acids created a barrier c: formation of microspheres or vesicles d: rna catalyzed the formation of membranes

In meiosis ii during anaphase ii which structures separated homologous chromosomes or sister chromatids

Is this mrna or rna need need the answer in a hurry
