The population of fish will decrease.
The population of grazing animals will decrease.
<h3>What is drought?</h3>
A drought is a prolonged period without enough precipitation/water to support people, animals or crops.
With less water, fish and other creatures have fewer places to dwell, swim, and evade predators. In the near run, shrinking streams and lakes necessarily result in fewer fish. Drought conditions can cause water temperatures to rise, affecting cold-water species such as native trout.
The population of grazing animals would decrease as the grass is a food source and without their food source, there would be no source of staying meaning that they would result to finding new food sources through migration likely.
I can't answer 1 but 2=First, make sure you weather proof the house, than go from there and try anything you think is necessary in this situation.
Enzymes (Catalysts) lower the required activation energy, allowing the reaction to happen more quickly.
The answer is A. RNA polymerase will be making an mRNA using a single DNA strand as a template. So, for example if the DNA strand is AGGCAGC the mRNA strand will be UCCGUCG.
U= uracil which replaces thymine in mRNA molecules.
