A class is designing an experiment about duckweed growing conditions. The hypothesis for the duckweed experiment is, “if duckweed is grown at pH 5, then it will grow at the same rate as when grown
at pH 7, or normal pH, because it can tolerate mildly acidic environments."
Identify the control group in this experiment.

duckweed at pH 7

then second one is

duckweed at pH5

Explanation:

jus did it.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
