Explanation:
I have a question are you asking what are the molecules of a shark or something
The type of control is described by the response of the operon when no regulatory protein is extant. In the case of negative regulator, the genes in the operon are distinct unless they are switched off by a repressor protein. Therefore the operon will be turned on essential (the genes will be prcise) when the repressor in inactived. In the case of positive control, the genes are distinct only when an active regulator protein, an activator, is present, Thus the operon will be turned off when the positive regulatory protein is missing or inactivated.
The water level in the bucket would drop.
This is because the pebbles have a greater density than water - they displace more water (when floating in a cup), than their volume. Thus the water displaced by the cup of floating pebbles has to be more than the volume of pebbles in the cup.
