In Botany as well as Zoology, one can recognize classical (or pure) branches, interdisciplinary branches and applied branches ref.: Human Body (Eyewitness Science) read Human Body (Eyewitness Science). When the biologist begins his investigation with some end (whether in the mode of discovery or the mode of scientific presentation), he is creating an account of conditional necessity. The other sort of necessity is absolute necessity that is the result of matter following its nature (such as fire moving to its natural place) read Grasshoppers (First Step Nonfiction) (First Step Nonfiction (Hardcover)) online.
