Astudent 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

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

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.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
