Answer:
The correct answer is - the more specialized pharyngeal jaws are for one diet, the less adapted they are for the ingestion of other foods
Explanation:
Pharyngeal jaws are also called throat jaws and are specific for the prey. These jaws have strong muscles and plastic or easy-to-modify teeth. If an organism has pharyngeal jaws specialized for a specific diet or prey it will have lesser chances to adapted well according to the new diet. For instance, pharyngeal jaws highly specialized for scale eating will not be able to adapt well if the fish ingests algae.
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.
