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 correct answer that would best complete the given statement above would be this: A potential benefit of recruiting slow oxidative fivers for contraction before recruiting fast oxidative and fast glycolytic fibers might be because they are slower to respond, slow oxidative fibers must be stimulated first in order contract simultaneously with the faster fibers. Hope this answer helps.
