Answer:
Hypotonic solution
Explanation:
hypertonic solution is the one you get when the solute concentration of the water is higher than that of the cells.
isotonic solution is the one you get when the solute concentration of the cell and the water are the same.
hypotonic is the one that you get when the solute concentration of the cell is higher than that of the waters.
Solute concentration being low reminds me of water. Hypo kind of sounds like hippo and hippos love water. You can use this to memorize the difference between hypertonic and hypotonic solutions.
sorry if the grammer is bad i tried my best.
The brain imaging technique you refer to is the MEG.
This question would be better placed under the Chemestry section
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.
