A manager for a factory farm is ordering corn. Each animal eats 3.2 kg of corn per day. Considering all the inputs associated with growing corn in an industrialized manner (fertilizers, pesticides, machinery, etc.) it takes 3 liters of oil to produce 20 grams of corn. How much oil is used to grow the corn for a one week supply of corn for the 3000 animals the manager must feed? Make sure your answer is in scientific notation and all units are present.

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?
