<span>Ethology, zoology, biology, and physiology are all branches of science or studies. </span>
<span>Biology studies the life aspects of all living organisms while ethology pertains to animal behavior only.</span>
Zoology is a branch of biology<span> that deals with animals' </span>structure, embryology, evolution, classification, habits, and distribution while physiology is the branch which studies the ways in which a living organism or its body functions.
