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.
The answer is “C”. Natural selection is about ones traits being better than another’s which allow it to survive in the wilds longer.

Names are universal
Explanation:
Current naming system that is followed all over the world is called binomial nomenclature. There are many significant and useful features of this classification system however one of the most important feature is the universality of the name.
The scientific names of organism are usually Latin derived and composed of two parts among which first is genus name and second is specie name.
For example<u>: Rosa indica</u> is the scientific name of Rose and it is same all over the world. Unlike common names we dont have to search for name to make others understand which flower we are talking about because if we know scientific name anyone can understand it.
Hope it help!
