a. The separation stays the as it is the same experiment independent of the medium.
b. The separation decreases because the frequency of the light decreases in the water.
c. The separation increases because the wavelength of the light increases in the water.
d. The separation decreases because the wavelength of the light decreases in the water.

Anne S. Moffat, in a paper in Science "Engineering plants to cope with metals" (Ref. 41) says: "Many plants cope with
metals by binding them in complexes with a class of peptides called phytochelatins and sequestering the complexes inside their cells. Now three groups have isolated genes for the enzymes, called phytochelatin synthases, that make the metal-binding peptides when the cell is exposed to toxic metals. ... After searching genome databases, they also found counterparts of the plant genes in the roundworm Caenorhabditis elegans." What are the implications of finding the same genes to inactivate metals in both plants and animals?
