The four muscles of the rotator cuff are the supraspinatus, infraspinatua, teres, and subcapularis. Hope this helps!
Answer:
Silencer
Explanation:
Silencers are the position and orientation free sequences that are present outside the protein-coding sequence of a gene. Silencers serve as a binding site for some transcriptional regulatory proteins that tend to inhibit gene expression. Binding of these "repressor" proteins to the silencers inhibits the gene expression.
The deletion of silencers from DNA would increase the rate of the gene expression as the inhibitory transcription regulatory proteins do not have binding sites to inhibit the gene expression. Therefore, the deletion of silencer sequences of the beta-globin gene would have caused the increased rate of its expression.
Answer:
Option A
Explanation:
The flower cells are hypertonic to fresh water but hypotonic to the salt solution.
Flower cell is hypertonic to fresh water, this means that the amount of solute in the solution outside the flower cell is higher than the solute content inside the flower cell.
While when a flower cell is hypotonic, it means that the amount of solute in the solution outside the flower cell is lower than the solute content inside the flower cell.
This is the reason why a flower plant placed in vase of water stood and become erect, while the same flower placed in a salt solution wilted.
Hence, option A is correct
