Heat is required to solid for melting and to liquid for evaporation so these are endothermic processes.
The reaction of aqua regia is exothermic because it releases heat when the acids interact with metals, causing a very strong and aggressive reaction that can dissolve gold and platinum.
Exothermic because the heat of formation is -566. Exo- is negative and Endo- is positive.
No. Heat is given out (liberated) in exothermic reactions not endothermic. exo = out, therm = heat. Endothermic reactions take in heat energy from the surrounding wshich cause the surrounding temperature to decrease. endo = in.
The organ system that is the same in both vertebrates and squids is the nervous system. Both have a complex network of neurons that allow for coordination of bodily functions and responses to stimuli.
The opposite of exo- is endo-.
if u mean skeleton then exo
No! It has an exo skeleton
Endoskeleton
Exo- is the prefix opposite to endo-, as in exoskeleton and endoskeleton.
They're invertebrates. They have no skeletal structure at all
Humans and fish have endo skeletons and grasshoppers have exoskeletons (thats why you hear a crack if they are stepped on).
There's 3 : inner, outer, & middle. (endo - exo - meso)
substances move. endo folds in , and exo exits
It is endoskeleton. Seahorses have an interior skeleton.
Heat is required to solid for melting and to liquid for evaporation so these are endothermic processes.
The 'endo' in the word 'endoskeleton' is a big clue because it means 'inner.' So, yes, a St. Bernard has an endoskeleton. The opposite of endo is exo. An exoskeleton is an 'outer skeleton.'
