Both aerobic cellular respiration and lactic acid fermentation produce atp, though in different amounts. these two atp-producing processes have some major differences as well as some similarities. what do aerobic respiration and lactic acid fermentation have in common? a) they produce a sour taste. b) atp production begins with glucose. c) they require an electron transport system. d) pyruvate serves as the final electron acceptor.

What is called the "building block" of life?

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?
