The phylogeny chart shows the evolution of camels. Camelus is the modern-day camel. Based on this chart, which three statements are true?

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
