<em>Because sometimes building these facilities is expensive and they usually have to be built in remote areas and burning fossil fuels has also been cheaper than using renewable energy in the past. Another issue is that the form of energy isn't available all the time.</em>

Answer:
The enzyme will no longer bind to the substrate, slowing or stopping the chemical reaction
Explanation:
The enzyme will get denatured and therefore its active site (that binds the substrate) will be deformed and unable to catalyze reactions. The enzymes, mostly made of folded proteins, are made stable by the interactions between the protein’s amino acids side groups. Changes in the pH of the solution influence the charges of these groups hence altering their interactions. This causes the protein enzyme to deform causing it to lose its function.
Amphibious because they only have gills and not gills and lungs which falls under the category of being amphibious.
The correct answer is A, the "promoter" site is the RNA polymerase binding site on a typical gene. This is how the process of gene expression begins. The RNA polymerase (a protein that builds RNA) binds to the promoter site of the DNA strand. It then begins the process of 'transcribing' the DNA code into an RNA strand, which can then be 'translated' into an amino acid chain to form a protein, which is the expression of the gene.
Having a controlled group is very important.
Reason: If scientists did not have a controlled group then, they would have data for the test but they might know if the results changed or not. Scientists need a controlled group because the controlled group is like the original. They need the original group to help them know what improved or did not improve.
For example, if you were testing whether or not different types of music helps with studying, then you will need a group that does not listen to music so you can know if different types of music actually improve or just make studying worse.
Having a controlled group helps you know the difference between observations in a easier way. The controlled group is not something people should ignore. It might seem useless at first but, when a person starts to finish up their project or test then, they will understand why a controlled group is important. By the time they do, it might be too late so make sure you people use a controlled group(Especially in the Science Projects).
(Hope this helps : ) )
