Giancarlo sets up 5 test tubes: pH 3, pH 5, pH 7, pH 9, and pH 11. Each test tube has 50 g of the pH buffer solution, 10 g of the enzyme DNA polymerase, and 50 g of the enzyme's substrates (a short piece of a DNA chromosome and free RNA nucleotides). He measures the activity rate of DNA polymerase in each test tube by measuring how many copies of the DNA chromosome it produces as products of its reaction. Which statement BEST describes the components of Giancarlo's experiment?

The phylogenetic tree illustrates the relationship between humans and our closest living relatives. the tree was based on biochemical comparisons, including dna and amino acid sequences. according to the biomolecular data, we could infer that a) the four organisms do not have a common ancestor. b) humans are more closely related to chimps than any other apes. c) chimps are more closely related to gorillas than they are to humans. eliminate d) there is no evidence if any relationship between the four branches on the tree.
