Twenty cuttings were taken from one plant and planted in four containers of sand. two containers had a ph of 6.0, and two had a ph of 8.0. when the cuttings matured, all of those grown in a ph of 6.0 had pink flowers, and all of those grown in a ph of 8.0 had blue flowers. one explanation for these results is that the sand at one ph contained a dye that changed the flower color. the best alternative explanation for these results is that -

The difference in pH caused the genes for flower color to be expressed differently

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
