The examiner tap from the body feels for abnormal resistance and listens for signs of abnormalities
Cutting And separation of tissues to revealthe relationship
Dissecting a dead human body
Study of more than one species in order to examine structural similarities

the study of structure
Change in the genetic composition of a population of organisms
A single complete individual, the baby
a group of organs with a unique Collective function. example the circulation respiratory or digestive
A structure composed of two or more tissue types at work together to carry out a particular function examples skin pancreas
