Study Notes
Evolution
- Organisms evolve from common ancestors.
- Natural selection drives evolution "selecting" traits for survival.
- Evolution explains the diversity of traits in different species.
- Evolution also explains common traits in different species.
- DNA is the universal genetic language of all organisms.
What is Life?
- Life contains several properties: order, evolutionary adaptation, regulation, energy processing, growth and development, response to the environment, and reproduction.
Energy & Matter
- Energy flow starts from the sun as light.
- Plants convert light energy into chemical energy.
- Consumers feed on organisms or their remains.
- When consumers consume producers, they get chemical energy.
- Chemical energy is lost as heat when performing work.
- Decomposers return chemicals to the soil and air.
Interactions
- Interactions can occur at any level of the biological hierarchy.
- External interactions: between an organism and its surroundings.
- Internal interactions: within an organism.
Internal Interactions
- A stimulus triggers a response in an organism.
- Feedback regulates response.
- Negative Feedback: the response decreases the stimulus.
- Positive Feedback: the response increases the stimulus.
Organization
- The Biosphere contains all living things and their habitat.
- Ecosystems are all components within a particular environment.
- Communities are the different organisms in a particular environment.
- Populations are a group of the same species living in a specific area.
- Organisms are individual living things.
- Organs are body parts with specific functions.
- Tissues are groups of cells working together for a specific function.
- Cells are the basic unit of life; single-celled or multicellular.
- Organelles are functional components of cells.
- Molecules are chemical structures composed of two or more atoms.
Information
- Genetic information is stored in DNA.
- DNA is a double helix made of two strands.
- Nucleotides are a building block of DNA strands.

- Biosphere: All life on Earth and the places it exists, e.g., from ocean floor to atmosphere
-
Information: DNA as the blueprint for life, a double helix composed of nucleotides
-
Energy and Matter: Flow of energy starts from the sun, converted by producers (plants) to chemical energy, passed through consumers
- Energy is lost as heat when used for work, like muscle contraction or growth
- Chemicals cycle through ecosystems, returning to soil and air through decomposers
-
Interactions: Biological systems interact with each other and the environment.
-
Evolution: Organisms are modified descendants of common ancestors, shaped by natural selection.
- Natural selection favors traits that promote survival and reproduction
- Explains diverse traits between species and common traits among related species
What is Life?
- Characteristics of life:
- Order
- Evolutionary Adaptation
- Regulation
- Energy processing
- Growth and development
- Response to the environment
- Reproduction
Classification of Life
- Taxonomy: Science of classifying organisms
- Domains: Three main categories for all living things
- Bacteria: Single-celled prokaryotes (lack membrane-enclosed organelles)
- Archaea: Single-celled prokaryotes (lack membrane-enclosed organelles)
- Eukarya: Eukaryotes (have membrane-enclosed organelles) including single-celled and multicellular organisms
Scientific Inquiry
- Scientific Method: A systematic approach for scientific investigation:
- Make Observations: Notice details about the world
- Ask Questions: Develop specific inquiries
- Form a Hypothesis: A testable explanation for the observation
- Conduct an Experiment: Test the hypothesis with a controlled experiment
- Analyze Results: Interpret data and draw conclusions
- Experimental Design: Ensure that only one factor (variable) is tested at a time.
- Controlled Experiments: Compare an experimental group to a control group
- Variables: Factors that can change during an experiment
Mice as Examples
- Evolution: Inland and beach mice demonstrate evolution
- Organization: Hierarchy of structure within mice
- Molecule: Gene for fur color
- Cell: Contains the gene
- Tissue: Skin with colored fur
- Organ: Heart
- Information: Genes carry instructions for fur color
- Energy and Matter: Mice consume food for energy, cycling matter through their bodies
- Interactions: Mice interact with their environment and other organisms
