A phyloGENETIC tree is not the same thing as a taxonomic tree, which is what Cal described. rRNA and molecular studies are used in phylogenetics to determine relations between species.
1 As the light intensity increases, the rate of photosynthesis increases. 2  However, the rate will not increase beyond a certain level of light intensity. 3  At high light intensities the rate becomes constant, even with further increases in light intensity, there are no increases in the rate.
Aim: To see if raising the light intensity increases the rate of. photosynthesis. Prediction:I predict that raising the light intensity will increase. the rate of photosynthesis. I think this because light is the most. important thing needed for photosynthesis. I then think that the rate.
