Active transport requires cell energy and osmosis doesn't is the statement concerning osmosis and active transport that is correct.
Active transport is the movement of dissolved substances across a cell membrane from a region of lower concentration to a region of higher concentration. Active transport requires an input of cellular energy to perform the movement, while osmosis is a form of passive transport which involves the movement of molecules through a semipermeable membrane from a region of higher concentration to a region of lower concentration without the use of energy.
The results will most likely be valid because the scientists kept getting the same results after REPEATED experiments. If they just conducted one experiment then they would not have been sure if what happened was a fluke or if another thing would happen after another experiment.<span />
Louis Pasteur effectively disproved the spontaneous generation concept by performing research that displayed exposure to fresh air was the trigger of the microbial growth.
