• Bacteriology is the study of bacteria
• Biochemistry is the use of chemistry in the study of living things
• Biological Earth Science is the use of earth science, such as geography, in the study of living things
• Biological Psychology is the use of biology in psychological studies
• Biophysics is the use of physics in the study of living things
• Conchology is the study of shells
• Cytology is the study of cells
• Ecology is the study of the relationships of living things to each other and to their environment
• Embryology is the study of the formation and development of living things from fertilization to birth as independent organisms
• Endocrinology is the study of hormones and their actions
• Entomology is the study of insects
• Ethology is the study of animal behavior
• Genetics is the science of heredity and the lifelong development of living things
• Helminthology is the study of worms
• Herpetology is the study of reptiles and amphibians
• Hypothesis:

  • A tentative answer or solution to a problem
  • Must account for all observed facts and be testable
• Experiment:

  • A recreation of a phenomenon or event by a scientist to produce valid and reliable evidence
  • Involves precise collection of data systematically related to the hypothesis
• Drawing of Conclusion:

  • After experimentation, a scientist draws a conclusion based on data and explanations that support the hypothesis
• Theory:

  • Formed when a hypothesis proves true in subsequent similar experiments
  • A general statement, a scientifically accepted generalization based on tested hypotheses designed to explain observations
• Continuous Experimentation:

  • New theories are subjected to continuous experimentation
  • If a theory survives, it becomes a valid scientific law
• Histology is the study of tissues
• Ichthyology is the study of fishes
• Malacology is the study of mollusks
• Mammalogy is the study of mammals
• Microbiology is the study of microorganisms

• Parasitology is the study of animals that live and subsist on or in other animals
• Pathology is the study of diseases, generally in animals
• Pharmacology is the study of the actions of chemicals on and in living things
• Phylogeny is the study of the development of a group or race
• Physiology is the study of normal functions of living things
• Protozoology is the study of one-celled organisms
• Virology is the study of viruses
• zoogeography is study of the land and its animals
• Theories on the origin of life:

  • Divine Creation Theory: life comes from a supernatural form
  • Marine Theory: life originates from the sea
  • Cosmozoic or Interplanetary Theory: life comes from outer planets as spores and germinate on earth
  • Abiogenesis or Spontaneous Generation Theory: life arises spontaneously from non-living things
  • Evolutionary Theory: life results from a chain of chemical reactions giving rise to living protoplasm which gradually modifies to present forms of life
