Answer:
See the answer below
Explanation:
In order to test for starch and distinguish the beaker containing a mixture of startch and water, a small quantity of the solutions in each beaker should be taken and and drops of iodine added. The solution that gives off a <u>blue/black</u> color from the yellow/brown color of the iodine would be the starch water solution.
<em>Generally, starch turns iodine solution to blue/black from the usual yellow/brown color of the substance.</em>
A possible answer could be parasympathetic.
The parasympathetic nervous system is the nervous system is characterised by things such as mentioned above "slower respiration and heart rate" because it is the system that responds to stimulation, which can occur during eating, digestion, defecation, etc.
It is also reponsible for well known reaction such as "flight-or-fight" and other similar ones.

The correct answer is "<span>It will perform less than optimally unless the pH was increased."
This is because the curve on the graph shows pH versus reaction rate. If we follow the x-axis (the bottom one) to a pH of 7, it is at an extremely low reaction rate compared to other points of the graph. If we continue along, we see that the reaction rate increases as the pH increases. Therefore, the enzyme will perform less than optimally unless the pH is increased.
