Study Notes
Themes and Concepts of Biology
-
Life on Earth: Life on Earth, as viewed from space, appears diverse. Early life forms were microorganisms, appearing long before plants and animals. Mammals, birds, and familiar flowers evolved relatively recently (130-200 million years ago). Humans have existed for the last 2.5 million years, with modern human characteristics emerging 300,000 years ago.
-
Properties of Life: All living organisms share eight characteristics: order, response to stimuli, reproduction, adaptation, growth and development, regulation (homeostasis), energy processing, and evolution.
-
Order: Living organisms are highly organized, composed of atoms, molecules, and cells, with increasing complexity in multicellular organisms.
-
Sensitivity (Response to Stimuli): Organisms respond to various stimuli, displaying positive (movement towards) or negative (movement away) responses.
-
Reproduction: Single-celled organisms reproduce by duplicating and dividing their DNA; multicellular organisms create specialized reproductive cells for new individuals. DNA is transferred to offspring, resulting in similar characteristics.
-
Adaptation: Living organisms exhibit a "fit" to their environment; adaptations are evolutionary traits that enhance survival and reproduction. Adaptations are influenced by natural selection.
-
Growth and Development: Organisms grow and develop following instructions from their genes, exhibiting similar characteristics to their parents.
-
Regulation (Homeostasis): Organisms maintain internal stability despite environmental changes through a variety of regulatory mechanisms. For example, temperature regulation.
-
Energy Processing: Organisms obtain energy from various sources – sunlight, or chemical energy from molecules.
Levels of Organization
- Atom: The fundamental unit of matter.
- Molecule: Two or more atoms bound together.
- Macromolecules: Large molecules created by combining smaller units (monomers). Examples include DNA (deoxyribonucleic acid).
- Organelles: Small structures within cells performing specific functions.
- Cells: Fundamental units of structure and function of life.
- Tissues: Groups of similar cells with a common function.
- Organs: Structures made up of different tissues working together.
- Organ Systems: Groups of organs that work together.
- Organisms: Individual living entities.
- Populations: Individuals of the same species in a given area.
- Communities: Populations of different species living together.
- Ecosystems: Living and non-living components of a given area.
- Biosphere: The sum of all ecosystems on Earth.
Branches of Biological Study
- Biology includes many specific branches like molecular biology, microbiology, neurobiology, and paleontology.
Scientific Inquiry
- Inductive Reasoning: Making general conclusions from specific observations.
- Deductive Reasoning: Making specific predictions based on a general principle or law.
- Hypothesis-Based Science: A type of scientific inquiry using hypotheses (testable explanations) and experiments.
- Hypothesis Testing: Evaluating a hypothesis through experimentation, involving variables (changeable factors) and controls (unchanging factors).
- Reporting Scientific Work: Sharing findings through peer-reviewed publications, promoting communication and collaboration among scientists.
Basic and Applied Science
- Basic Science: Expanding existing knowledge, not necessarily focused on immediate applications.
- Applied Science: Solving real-world problems using scientific principles and knowledge. Applied science often relies on the fundamental discoveries made by basic research.
Scientific Ethics
- Ethical Considerations: In science, scientists must ensure their work does not harm individuals, animals, or the environment. Research ethics must be considered and properly balanced with other factors such as financial, legal, and safety factors.
