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.
Hope this helps, and hope I'm the brainiest! :)</span>
The exchange of useful chemicals between organisms and their abiotic environment is an example of matter cycling.
<h3>What is the matter cycling?</h3>
Matter cycling refers to the cyclic movement of matter between biotic factors and abiotic factors.
This process (matter cycling) is fundamental for the survival of organisms and health of an ecosystem.
In conclusion, the exchange of useful chemicals between organisms and their abiotic environment is an example of matter cycling.

Answer:
1) Gene expression can be modified by Interactions with the environment
Explanation:
Environment factors such as temperature change for instance affects the expression of the genes for a particular trait and these genes can be modified too.
