One atom has a stronger electronegativity than the other. Each atom has a slight charge. Cells have both free and membrane-bound ribosomes. Give an example of a type of cell that would have a lot of membrane-bound ribosomes. Cite a specific reason why you think this type of cell will have many membrane-bound ribosomes.
Free ribosomes synthesize protein that remain inside the cell.
Membrane-bound ribosomes synthesize proteins that are excreted from the cell. Conclusions are based upon the result of a single experiment or observation. You might conclude that the results of an experiment support you hypothesis. Similar conclusions from many different investigators allow scientists to formulate a theory. A theory is a broader concept that encompasses conclusions from many different experiments.
