1 Properties of Life

2 What IS Zoology? Zoology – study of animals  Diversity  Organization

3 Properties of Life 1. Chemical Uniqueness ◦ Macromolecules-  Nucleic Acids  Proteins  Carbohydrates  Lipids

4 Properties of life 2. Complexity and hierarchical organization ◦ Cells  Organism  Population  Species ◦ Emergence- appearance of new characteristics.

5 Properties of Life 3. Reproduction ◦ Heredity- passing of traits from parents to offspring ◦ Variation- the differences of traits of different individuals

6 Properties of Life 4. DNA ◦ A, T, C, G ◦ Genetic Code- the sequences of bases that code for a specific trait.  Consistent through all living forms

7 Properties of Life 5. Metabolism ◦ Digestion ◦ Acquisition of energy ◦ Synthesis of molecules ◦ Metabolism is often used as an interaction of destructive (catabolic) and constructive (anabolic) reactions.

8 Properties of Life 6. Development ◦ Fertilization  adult form ◦ Metamorphosis- transformation of one form into another

9 Properties of Life 7. Environmental interaction ◦ Ecology- study of interactions that take place between organisms and their environment

10 Properties of Life 8. Movement ◦ Reproduction and Growth ◦ Responses to Stimuli
