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.
Answer:
Carbon dioxide
Explanation:
In a calvin cycle , glucose is produced mainly because of carbon dioxide. Generally in the light dependent phase of photosynthesis, carbon dioxide react with water in the presence of light and chlorophyll pigment to produce glucose as shown in the reaction below-
6CO2 + 6H2O → C6H12O6+ 6O2
This process of photosynthesis is also referred as carbon fixation as the inorganic carbon gets converted into high-energy organic molecules like glucose
human activity has used up and wasted all of earth's natural resources which is why we have resorted to harmful fossil fuels that have also contributed in the destruction on the environment.
Answer:
Moving magnetic fields pull and push electrons. Metals such as copper and aluminum have electrons that are loosely held. Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current.
Explanation:
The rodent will become extinct or die due to the drastic temperature increase in a short period of time.
