Process of photosynthesis makes glucose. Excess glucose is stored as starch, or made into cellulose in cell walls.
Answer:
the pH
Explanation:
The condition that should not be kept the same in each of the five test tubes is the pH.
Since <u>the aim of the experiment is to investigate the effect of pH on the activity of the lipase enzyme</u>, the pH is, therefore, the <em>independent variable</em>. Thus, it must be controlled or varied in all the test tubes in order to see its effect on the activity of the enzyme, which, in this case, would be the dependent variable.
(The 3 examples are:)
~ CO2 from burning fossil fuels
~ gas (methane) leaks from underground gas pipes
<span>~ methane from rotting material in landfills
</span>
(Other ones)
<span>~ combustion of fossil fuels (oil, coal, and gas)</span>
<span>~ deforestation (decreasing amount of plants that remove CO2 from the atmosphere)</span>
<span><span>~ industrial production that uses petroleum based products (mineral/metal production)
