Passage

Certain species of flowers attract more bees than others with the scent of their pollen. The pollen is found on a structure within the flower called the anther, which is located on top of another structure called the stamen. Flowers typically have multiple anthers and stamens.
Bees carry the pollen from the flowers on their legs. The bees move from flower to flower while collecting pollen.
Some of the pollen falls from their legs as they land on another flower. This depositing of pollen causes crosspollination to occur (fertilization of the other flowers). Three studies were conducted to study this process.
Study 1
For two flower species (A and B), pollen quantity per anther in milligrams (mg), anther quantity per flower in number, and percentage of stamens covered with pollen were recorded (see Table 1).

Study 2
Three study sites were established to determine the pollen collection rate of one species of bee for the flowers used in Study 1. In Site 1, Species A flowers were absent. In Site 2, Species B flowers were absent. In Site 3, both Species A and B flowers were absent.
Two pollen containers were placed at each site: one containing 50 mg Species A pollen and one containing 50 mg Species B pollen. The containers were left in place for 36 hours and the amount of pollen that was taken from the containers was measured. The results are recorded in Table 2.

Study 3
The researchers hand-pollinated flowers from a third species, Species C. They also observed the Species C plants being cross-pollinated by the bees in the area. All flowers were observed for 2 years. The scientists recorded the results in Table 3.
Q. Which of the following variables was controlled in the design of Study 2?
  • a)
    The amount of pollen placed at each site
  • b)
    The level of pollen on each flower
  • c)
    The total amount of pollen removed by the bees from each site
  • d)
    The number of bees present at each site
Correct answer is option 'A'. Can you explain this answer?
