It’s not the most visible by your picture. The correct answers are where the highest point of each line is because that is where the enzyme is working most efficiently.
Here are my answers but because of the unclear image , please check them with my explanation above:
Pepsin. = pH2
Salivary Enzyme = pH7
Trypsin = pH9
<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>

The answer is difference in density. We know that the high central density suggests the earth must be rich in nickel and iron and that much of the core must be liquid. This lower-density air then rises and is replaced by cooler, higher-density air. The result is atmospheric circulation that drives the weather and climate through redistribution of thermal energy.
