The concentration of carbon dioxide in parts per million (ppm) was measured for a closed container in several situations. Which of the following data collected would demonstrate the action of photosynthesis?

The data collected would demonstrate the action of photosynthesis as when the container included a plant exposed to light, carbon dioxide concentration went from 800 to 600 PPM

Explanation:

The data collected would demonstrate the action of photosynthesis as when the container included a plant exposed to light, carbon dioxide concentration went from 800 to 600 PPM.In a closed system, a decrease in carbon dioxide is evidence of photosynthesis, while an increase in carbon dioxide is evidence of cellular respiration. A plant in the dark will only carry out respiration, but in the light, the plant can carry out both respiration and photosynthesis.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
