What was shown by both redi’s and pasteur’s experiments?

Their experiment showed that the flies did not come directly from meat but flies laid their eggs there (disprove the spontaneous generation).

Explanation:

Redi put meat in three different jars one jar with covering and another without covering and the 3rd jar was sealed. He disproved spontaneous generation theory in this experiment. He showed that maggots did not come directly to meat but came from eggs laid by flies The sealed jar had no maggots in the meat.

Pasteur also checks the spontaneous generation theory by putting the boiling broth in different flasks, some open and some sealed. The conclusion he drew from this is that living things did not come from broth directly.

Thus, their experiment showed that the flies did not come directly from meat but flies laid their eggs there (disprove the spontaneous generation).

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
