How are photosynthesis and respiration related to each other? a: both are performed by all plants and animals. b: the products of photosynthesis, oxygen and glucose, are the starting substances of cellular respiration. two of the products of respiration, carbon dioxide and water, are the starting substances of photosynthesis. plants and animals depend on each other and these two important processes to survive. c: photosynthesis and respiration are not related to each other.

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?
