Morphology

activity = active (transparent) = act + ive + ity

Built from 'active' + '-ity'; the sense describing natural processes is a regular extension to denote processes that are 'active'.

Etymology

Activity comes from the root act meaning 'to do', which helps us think of parts of the body doing work. So in biology or medicine, activity names natural processes like muscle or heart work.
