Answer:
It allowed us to put a formation date on some geologic cross sections
Explanation:
Absolute dating techniques is an improvement on the older relative dating techniques which only give order of past events but with newer absolute dating techniques, those chronological events are sampled and analysed and more accurate numerical ages assigned to them.
This newer technique has vastly improved the way archaeologists find the age of ancient relics and geologists, rocks.
The law of conservation of charge states that electric charge can neither be created nor destroyed. In a closed system, the amount of charge remains the same. When something changes its charge it doesn't create charge but transfers it.
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.
