Base your answer on the information below and on your knowledge of biology. 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? (1) an electronic balance to measure the volume of soil in which each corn plant is grown
(2) a graduated cylinder to measure 30 mL of water for each plant daily
(3) a metric ruler to determine the mass of each plant each week
(4) a Celsius thermometer to determine the pH of the soil
The anthers are in the elevated position so that the pollinators will be attracted towards it, and that the pollen grains are easily carried away by the agents of pollination.
