Lesson 1

• Zoology


  The scientific study of animal life.
• Zoology


  It seeks to understand the sum total of all the properties of animals and animal population.
• Life


  The sum total of all body activities of an organism.
• Cellular Organization


  All organisms consist of one or more cells.
• Ordered Complexity

  All living things are complex and contain many complex molecular structures.
• Sensitivity


  All organisms respond to stimuli.
• Example of sensitivity is movement
• Growth Development and Reproduction


  All organisms are capable of growing and reproducing.
• Growth Development and Reproduction


  They possess hereditary materials that are passed to their offspring, ensuring that the offspring is of the same species.
• Energy Utilization


  All organisms take in energy and use it to perform many kinds of work.
• Homeostasis


  All organisms maintain a relatively constant internal conditions.
• Homeostasis


  State of balance within all physical systems needed for a body to function properly and survive.
• Examples of homeostasis are body temperature and blood sugar
• Evolutionary Adaptation


  All organisms interact with other organisms of non-living environment in ways that influence their survival, and as a consequence, organisms evolve adaptations to their environment.

• Zoogeography


  The study of the distribution of animals according to space and region.
• Animal Embryology


  The study of the development and growth of the new individual within the egg or within the mother.
• Genetics


  The study of the laws of heredity and variations.
• Ecology


  The study of the relationships of animals to their environment.
• Taxonomy


  The study of animal classification.
• Paleontology


  The study of fossil animals and their distribution in time.
