A student poured a solution of bromothymol blue indicator into one test tubes. Then, he placed an aquatic plant in it, as shown below. He placed a stopper on the test tube and placed it in a sunny window for 24 hours. After one day, he then placed the test tube in the dark for 24 hours. Bromothymol blue turns from blue to yellow in the presence of CO2.

Ifound this on google “increases in temperature increase molecular activity, and can result in a higher rate of collisions between enzymes and substrates. if the temperature rises too high, however, the enzymes could become denatured, and the positive effects of the temperature increase could be nullified.” for more information go to the website below › i hope this you for what your looking for. can you plz mark me brainliest?

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
