This event is sometimes called the "Cambrian Explosion," because of the relatively short time over which this diversity of forms appears
Answer:
D.) repressor DNA-binding site mutation
Explanation:
lacl prevents the repressor polypeptide is a mutant that prevent operon from binding lactose, and thus will bind to the operator and be non-inducible.. This mutant will represses the lac operon whether lactose is present or not and the lac operon will not be expressed. It is also called“super-supperesor".
The lacI locus – One type of mutant allele of lacI (callled I-) prevents the production of a repressor polypeptide or produces a polypeptide that will not allow to bind to the operator sequence.
This is also a constitutive expresser of the lac operon because absence of repressor binding permits transcription.
This patient both has left-sided heart failure and right-sided heart failure. In left-sided heart failure, this patient exhibits increasing shortness of breath on exertion as well as three pillow orthopnea which indicates pulmonary congestion. This is because of pooling of blood in the pulmonary circulation. Bipedal edema, in this patient is a grade 2 bipedal edema, reflect right-sided heart failure as there is pooling of blood in the systemic circulation, causing transudation in the most dependent areas of the body.
