Two scientists want to determine if dolphins vocally mimic the pitch of our voices in attempt to communicate. The scientists track each time a given dolphin's vocalization matches the pitch of their voices when the scientists are talking, but not directly communication with the dolphin. Then, they record the pitch of another dolphin's vocalization when the scientists are talking directly to the dolphin. Both times the scientists talked for 3 minutes. Identify each of the following parts of this experiment below by matching them together.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
