Changing the genes in a corn plant to make them resistant to insects
Answer:
The correct answer is- hormone signal amplification
Explanation:
The signals that are received by the cell can be amplified in the cell which results in the production of more than one molecule of the product. There is a signal pathway in every cell and the longer the signal pathway the more amplification chances are there.
For example, one membrane receptor is able to produce 10 secondary messengers and each secondary messenger generates 10 mRNA transcript so here the signal amplified by 1000 folds.
So in this question, it is seen that a small amount of releasing factor causing the release of a much greater amount of cortisol which shows the example of hormone signal amplification.
The answer is the base sequence of gene's promoter.
DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.
<span>During the peak of industrialization, there was a drastic change in the environment in Europe. Due to increased use of fossil fuels to run machines, the environment in urban centers was black due to soot produced by industries and settled on buildings and the environment. Therefore black moths were able to camouflage in this environment hence evade predators. White moths were, conversely, more conspicuous in this environment hence predated on more. The black moths were, therefore, more likely to pass their genes to the next generation compared to white moths</span>
