Zoology Overview and Key Concepts

Zoology

• Definition: Zoology is the scientific study of animals, their behavior, physiology, classification, and distribution.

• Branches:

  • Entomology: Study of insects.
  • Ornithology: Study of birds.
  • Ichthyology: Study of fish.
  • Mammalogy: Study of mammals.
  • Herpetology: Study of reptiles and amphibians.

• Key Concepts:

  • Animal Classification: Organisms classified into Kingdom Animalia, Phyla, Classes, Orders, Families, Genera, and Species.
  • Evolution: Understanding of natural selection, adaptation, and speciation.
  • Physiology: Study of animal functions and processes (e.g., circulatory, respiratory, and nervous systems).
  • Behavior: Includes instinct, learning, and social behaviors in animals.

• Ecology: Study of animal interactions with their environment and ecosystems.

Chemistry

• Definition: Chemistry is the branch of science that studies the composition, structure, properties, and changes of matter.

• Subfields:

  • Organic Chemistry: Study of carbon-containing compounds.
  • Inorganic Chemistry: Study of inorganic compounds, metals, and minerals.
  • Physical Chemistry: Study of the physical properties and behavior of chemical systems.
  • Analytical Chemistry: Techniques for analyzing substances to determine their composition.

• Key Concepts:

  • Atoms and Molecules: Basic building blocks of matter; atoms consist of protons, neutrons, and electrons.
  • Chemical Bonds:
    • Ionic Bonds: Electrostatic attraction between oppositely charged ions.
    • Covalent Bonds: Sharing of electron pairs between atoms.
  • Reactions: Processes where reactants transform into products.
    • Types of Reactions: Synthesis, decomposition, single replacement, double replacement, combustion.
  • pH Scale: Measures acidity or alkalinity of a solution (0-14 scale).

• Thermodynamics: Study of energy changes in chemical reactions, including concepts like enthalpy, entropy, and Gibbs free energy.

• Periodic Table: Arrangement of elements based on increasing atomic number and similar properties; groups and periods indicate relationships among elements.

Zoology

• Zoology involves the scientific exploration of animal life, focusing on behavior, physiology, classification, and distribution.
• Major branches of zoology include:
  • Entomology: Investigates insect species and their roles in ecosystems.
  • Ornithology: Studies various bird species, their behaviors, and habitats.
  • Ichthyology: Examines fish, including their physiological adaptations and ecological importance.
  • Mammalogy: Focuses on mammals, exploring diverse species’ adaptations and evolutionary history.
  • Herpetology: Concerned with reptiles and amphibians, studying their biology and conservation.
• Key concepts in zoology encompass:
  • Animal Classification: Organizes life into hierarchical taxonomic ranks leading from Kingdom Animalia down to Species.
  • Evolution: Centers on natural selection processes, adaptations, and the phenomenon of speciation influencing animal diversity.
  • Physiology: Analyzes various bodily functions such as circulatory, respiratory, and nervous systems in animals.
  • Behavior: Explores instinctual and learned behaviors, as well as social interactions among different species.
  • Ecology: Investigates how animals interact with their environments and contribute to ecosystem dynamics.

Chemistry

• Chemistry examines matter’s composition, structure, properties, and the transformations it undergoes.
• Chemists break the field into several subfields including:
  • Organic Chemistry: Studies compounds mainly composed of carbon, focusing on their structures and reactions.
  • Inorganic Chemistry: Investigates inorganic compounds such as metals and minerals.
  • Physical Chemistry: Looks at the physical properties and behaviors of chemical systems, relating to thermodynamics and kinetics.
  • Analytical Chemistry: Involves techniques to analyze substances to ascertain their chemical composition.
• Core concepts in chemistry are:
  • Atoms and Molecules: Fundamental units of matter, with atoms made up of protons, neutrons, and electrons.
  • Chemical Bonds: Interaction between atoms, including:
    • Ionic Bonds: Formed through the attraction between charged ions.
    • Covalent Bonds: Created by the sharing of electron pairs between atoms.
  • Reactions: Processes where reactants undergo transformations to form products.
  • Types of Reactions: Includes synthesis, decomposition, single and double replacement, and combustion reactions.
  • pH Scale: A logarithmic scale ranging from 0 (strongly acidic) to 14 (strongly alkaline), used to measure the acidity or basicity of solutions.
  • Thermodynamics: Analyzes energy transfer in chemical reactions, with concepts such as enthalpy, entropy, and Gibbs free energy.
  • Periodic Table: Organizes elements by increasing atomic number; features groups and periods that highlight similarities and relationships among elements.
