The average adult heart beat average is 70-75 beats per minute. Children have a higher rate in the 80's and 90's, depending on their age.The younger they are the faster the h â¦ eart rate. Females, generally, have a slightly higher heart rate than males. Heart rate also depends on your age and what you're doing.ut on average, studies have shown that a hedgehog's resting heart rate is in t â¦ he range of 190 to 280 beats per minute and ~147 beats per minute when sleeping. During hibernation â a state of extreme energy conservation â the heart rate can drop to an average of just under 14 beats per minute.
Symbiogenesis, or endosymbiotic theory, is an evolutionary theory that explains the origin of eukaryotic cells from prokaryotes.It states that several key organelles of eukaryotes originated as a symbiosis between separate single-celled organisms.olecular and biochemical evidence suggest that mitochondria developed from proteobacteria (in particular, Rickettsiales, the SAR11 clade, or close relatives) and chloroplasts from cyanobacteria (in particular, nitrogen-fixing filamentous cyanobacteria).
Definition of endosymbiosis. : symbiosis in which a symbiont dwells within the body of its symbiotic partner.
