Yes it is therefore the answer is true
Most likely the students are using a crude measurement of time, like a stopwatch. They would get the best results with a scientific apparatus that uses a computer and optical sensors. Even recording their dropped objects with a video camera and analyzing the video would give more consistent results. Results will also vary greatly if different people are taking the time measures instead of one person making all measurements.
Matter is anything that takes up space. Your mass determines how big, or small you are. Or, how big or small something is. Matter is in everything. Even air has matter. Humans are made of matter. Matter makes up atoms, carbon, cells, and everything else you can think of. (Except ideas)
Answer:
C) The Calvin cycle requires ATP and NADPH, which require sunlight to be produced
Explanation:
The light-dependent phase of photosynthesis includes the photolysis of water molecules. The released electrons are passed to PSII to PSI via electron carriers and finally to NADP+ to reduce it into NADPH.
Transfer of electrons via electron carriers also generates the proton concentration gradient which in turn drives ATP synthesis. ATP and NADPH formed during light reactions are used in the Calvin cycle as an energy source and electron donor respectively.
Hence, to continue, the Calvin cycle requires the synthesis of ATP and NADPH in the presence of light.
