A high school student is carrying out a science project. She plants alfalfa seeds, and encloses an area planted with one set of alfalfa seeds within a box covered in red cellophane (which reflects light of red wavelengths). She leaves another set of planted alfalfa seeds uncovered. What do you expect she'll find in these two alfalfa populations when her science project is over? The germination rate will be higher in the uncovered seed set. None of the other answer options is correct. Germination rates will be the same in both seed sets. The germination rate will be lower in the uncovered seed set.
