How does the double-helical structure of DNA explain how the molecules can be copied or replicated? A. Because of base pairing, each strand has all the information to serve as a template for the other strand
B. Each strand receives the information from the DNA polymerase attached to the replication fork
o
C. The nitrogenous bases on one strand are copied to the other strand
D. The nitrogenous bases line up on each strand and are attached to each other

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.

How can a geological time scale best be reconstructed? a) comparing vestigial structures in living species b) comparing homologous structures in living species c) examining homologous structures in fossil remains d) examining the written records of scientists from past cultures
