31) Scientists struggled for decades to synthesize (make) RNA in the laboratory despite the fact that they knew what all the basic building
blocks (chemical elements and molecules) were. This problem of not being
able to artificially create RNA demonstrates *
A. how baking complex foods in a commercial kitchen without any previous cooking
experience can lead to disastrous results
B. that scientists were not trying hard enough in the early days of abiogenesis
research and should probably have just given up
C. how dependent a particular outcome is on a very specific set of events occurring in
just the right order and under just the right conditions.
D. how any outcome is possible under any set of conditions.

How are gene and protein sequences used to classify organisms?

The accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. the accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. chimpanzees and gibbons are the most closely related the chimpanzee's closest surviving relative is humans orangutans are the primates least closely related to chimpanzees old world monkeys and gibbons are the most closely related

Select the correct answer from each drop-down menu. in an experiment, dr. travis examined the effects of calcium intake on osteoporosis, a condition that causes an increased risk of bone fractures. the amount of calcium is variable. the risk of bone fractures .
