Answer:
6 water molecules (and technically sunlight/energy)
Explanation:
The inputs of photosynthesis are water and carbon dioxide (and energy); water is used in the light-dependent reactions, and carbon dioxide is used in the light-independent. The water has to be there to replace the lost electrons in the chlorophyll that leave the thylakoids after being excited by the solar energy.
Explains the heart and breathing rate
Because if we're simultaneously moving/manipulating two different variables it can be very hard to determine why one variable is changing and why the other is changing. While this can be done with more complicated experimental designs, it usually is the case that scientists will only manipulate one variable and not two different ones.
Answer:
The answer is d. pyruvate
Explanation:
An oxidizing agent is the substance that gains electrons in a chemical reaction. At the end of the reaction it is reduced and its oxidation state increased.
A reducing agent is the substance that loses electrons in a chemical reaction. At the end of the reaction it is oxidized and its oxidation state decreased.
Pyruvate gains one electron, it is reduced from pyruvate to lactate; thus, pyruvate is the oxidizing agent.
NADH loses one electron, it is oxidized from NADH to NAD; thus, NADH is the reducing agent
