Guard cell o is ordered to opening and closing of stomata.
The whole water cycle is evaporation, condensation, precipitation, and then infiltration, and at last it is runoff.
Ocean is between the runoff and the evaporation. The rain runoff to the ocean and then start over the water cycle from evaporation.
Answer:
D. They block communication between enhancers and non-targeted promoters
Explanation:
Insulator sequences are the group of DNA sequences that protect the protein-coding regions of the DNA from the surrounding regulatory sequences. Some insulator sequences are present between the enhancers and promoters of a gene. These insulator sequences do now allow these enhancers to regulate the expression of genes by sending inappropriate signals.
However, if the insulator sequences are not present between the enhancers and promoters of certain genes but are located somewhere else, enhancers can upregulate the expression of these genes.
lowering the activation energy of the reaction.
