>increases the oceans' acidity and lowers pH
>increases the hydrogen ion concentration in the oceans but decreases the carbonate ion concentration and threatens the livability of the oceans for calcifying organisms
Explanation:
Answer: Option C
Explanation: The balanced chemical equation that explains photosynthesis is stated below:
6CO2(g) + 6H20(g) --------> C6H12O6 + 6O2(g) + energy (in from of ATP)
From the equation, 6 atoms of carbon C are contained in 6 moles of atmospheric Carbondioxide CO2, that reacted with 6 moles of water molecules H2O, contained in plant cells to yield 1 mole of glucose C6H12O6 and chemical energy in the form of ATP (adenosine triphosphate)
Answer:
It's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variable. When possible, control variables should be identified, measured, and recorded.
