When human DNA molecules and chimpanzee DNA molecules are heated to separate the two sides of the molecules from each other and then mixed together at cooler temperatures, strands of human DNA are able to form hydrogen bonds and base-pair with over 98% of the nucleotides in the chimpanzee DNA strands. Which of the following is the most logical conclusion to draw from this information?
A. Humans evolved from chimpanzees.
B. Ilumans and chimpanzees share a relatively recent common ancestor.
C. Chimpanzees evolved from humans.
D. Convergent evolution has led to similar nucleotide sequences in the two genomes.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.

The similarities of organisms in which two areas numbered above provide the best evidence for common ancestry between organisms in both locations?
