Mosquitoes can have bigger or smaller body sizes. Two parents that have medium-sized bodies have offspring. One of
their offspring has a small body, and one has a large body. How did the offspring end up with traits that are different from the traits of their parents? How did the gene combinations result in these traits?

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?
