19. CER. A group of students were interested in showing photosynthesis 12 points
occurring visually. They decided to use bromothymol blue which is an
indicator that turns green when there is a high concentration of carbon
dioxide and blue when there is a low concentration of carbon dioxide in
water. All the tubes started out blue, but students blew carbon dioxide
into two of the test tubes turning them green. They left one test tube of
each color as their control and put a piece of aquatic plant in the other
two tubes. Then, they put all four of these tubes outside (Monday 7 am).
When the students checked their tubes in the afternoon (Monday 1 pm),
they were so excited to see that tube D had turned blue! Carbon dioxide
was going away and being replaced with oxygen. When the students
checked their experiment early the next morning, tube B and D had both
turned green! Did photosynthesis occur during the experiment? Support
your claim with evidence explain your reasoning. *

Astudent completed a lab report. which correctly describes the difference between the âquestionâ and âhypothesisâ sections of her report? âquestionâ states what she is asking, and âhypothesisâ states the result of her experiment. âquestionâ states what she is asking, and âhypothesisâ states what she thinks the answer to that question is in âif . . then . . becauseâ format. âquestionâ describes what she is trying to find out, and "hypothesis" states the procedures and methods of data collection. âquestionâ describes what she is trying to find out, and âhypothesisâ states any additional information or prior knowledge about the question.

Me i need this asap during photosynthesis, the following reaction takes place: carbon dioxide + water + light energy â sugar + oxygen during cellular respiration, the following reaction takes place: sugar + oxygen â carbon dioxide + water + chemical energy given this information, how are photosynthesis and cellular respiration related? question 2 options: the products of photosynthesis are the reactants of cellular respiration. photosynthesis and cellular respiration both start with the same materials. photosynthesis and cellular respiration both produce the same materials. the same type of energy is found in both photosynthesis and cellular respiration.
