BIOLOGY A COMPLEX SCIENCE

and physicist of to-day deal with matter in .even smaller particles, 

 as they have discovered that atoms are further divisible into 

 protons and electrons, that is, particles that carry positive and 

 negative electrical charges. 



When a biologist looks at a living plant or animal he views it 

 in the light of his particular training. To some biologists, the 

 shape and form of the animal are of greatest interest. Others in- 

 vestigate the processes of the living organisms. 



Biology a complex science. Many divisions of biology have 

 been investigated, and there is so much known about each one 

 that they are sometimes thought of as distinct subjects. The 

 specialist who delves in a particular division is named in terms of 

 the specialty he follows. The specialists who are interested in 

 the study of bacteria (bacteriology) are known as bacteriologists. 

 Protozoology, likewise, has 

 protozoologists who are in- 

 terested in one-celled ani- 

 mals. Those who study 

 snakes are interested in 

 herpetology ; the specialist g^ 

 is a herpetologist. The en- O| PHv ' 

 tomologist studies insects; 

 he is concerned with the 

 science of entomology. 

 Some scientists may special- 

 ize in only one branch 

 of entomology. Bugs are 

 classed as Hemiptera ; stu- 

 dents interested in bugs are 

 hemipterists. Butterflies, the Lepidoptera, are the topic of study 

 of the lepidopterists. In each of these branches of biology we 

 have other subdivisions morphology, the study of the forms and 

 structures, and physiology, the study of the functions of the organs.
