USING SCIENCE SKILLS
A scientist set up a respiration chamber as shown below. She placed a mouse in flask B. Into flasks A, C, and D, she poured distilled water mixed with the acid-base indicator phenolphthalein. In the presence of CO2,
phenolphthalein turns from pink to clear. She allowed the mouse to stay in the chamber for about an hour.
40. Interpreting Graphics Based on Figure 9-2, how will the scientist be able to detect whether the mouse is carrying out cellular respiration?
a. the phenolphthalein in flask A will change from pink to clear. b. the phenolphthalein in flask B will change from pink to clear. c. the phenolphthalein in flask D will change from pink to clear. d. there won’t be a change in any flask
41. Predicting Assume that the scientist set up an identical respiration chamber, except that in this setup she placed a mouse that had been exercising on a hamster wheel. Then, the scientist measured the amount of CO2
given off by both mice at the end of 15 minutes. Predict which setup produced the most CO2.
a. the mouse not exercising produces more CO2.
b. the mouse exercising produces more CO2.
c. you can’t conclude which mouse will produce more CO2.
USING SCIENCE SKILLS
A student poured a solution of bromthymol blue indicator into three test tubes. Then, he placed an aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Bromthymol blue turns from blue to yellow in the presence of CO2.
