1 mph = 0.44704 mps 33 x 0.44704 = 14.75 mps
Always been taught that the vacuole holds the cell's water. I don't know about the other things <span />
The statement best that explains why cells were observed in more detail using compound microscope than a simple microscope is : compound microscope has greater magnification ability than the simple microscope .
This will allow us to observe the subject with a much smaller size, making it easier for us to observe the detail
hope this helps
