Morphology
the study of diet
Arthropods
embryology
Genes
biochemistry
An organ grinder.
Anatomy is the study of the physical structure of the body of an organism, such as that of a human, while physiology is the study of the function of the physical parts and systems that make up anatomy.By knowing the anatomy of an organism, we can determine some of its functions and how it interacts with the outside world (environment) and other organisms.For example, we can tell alot about the diet of an animal from its teeth, jaws, and skull.We can determine whether the organism is suited to a particular temperature range by its fur, hair, feathers, etc. and its fat tissue distribution.
