Question

A student designed an experiment to determine if air temperature had an effect on the rate of photosynthesis in corn plants.

Which tool is correctly paired with a procedure that could be used during this experiment?

A. an electronic balance to measure the volume of soil in which each corn plant is grown
B. a graduated cylinder to measure 30 mL of water for each plant daily
C. a metric ruler to determine the mass of each plant each week
D. a Celsius thermometer to determine the pH of the soil

Answer 1

B. a graduated cylinder to measure 30 mL of water for each plant daily

Step-by-step explanation:

Option A is incorrect because an electronic balance is used to measure the mass of an object and not the volume.

Option C is incorrect because a metric ruler is used to measure the dimension of objects and not the mass.

Option D is incorrect because a thermometer is used to measure temperature and not pH.

The correct option is B. A cylinder is applicable in the measurement of volume of liquids.
