You are running four different DNA samples (#1, #2, #3, #4) on a gel. For each of the questions below, determine which lane on the gel (A-E) shows the results you would predict to observe. Lane that shows the results for running Sample #1 only:

Chlorophyll is found in plant leaves and absorbs light from the sun to enable plants to perform photosynthesis. magnesium is an important component of chlorophyll. the concentration of magnesium ions is higher in the root-hair cells of plants than in the soil. which mechanism of ion uptake would best enable a plant to produce a steady supply of chlorophyll? osmosis diffusion passive transport active transport
