A scientist noticed that a particular organism's DNA was 30% Adenine and 20% Cytosine. Based on Chargaff's base-pairing rule, what can the scientist infer about the remaining makeup of that organism's DNA?
There is insufficient data to make a conclusion
It will have 30% Guanine and 20% Thymine.
It will have 30% Thymine and 20% Guanine.
It will have 30% Uracil and 20% Guanine

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
