Study Notes
History of Science
- UV radiation and lightning combined energy to form macromolecules from simple molecules (CH4, NH3, PO4, salts and H2O).
- Ribozymes, RNA, were the earliest self-replicating organisms.
- Early life forms were prokaryotes and anaerobic heterotrophs.
- Mutation from UV radiation led to predatory life forms.
- Chemosynthesis allowed organisms to create compounds using chemical energy.
- Photosynthesis utilized light energy for compound creation.
- Aerobic respiration evolved.
- Mitochondria became aerobic respirers.
- Endosymbiosis explained the formation of eukaryotes through prokaryotic uptake.
- Plastids (in plants) arose from photosynthetic cyanobacteria, and flagella arose from spirochete-like bacteria.
Research
-
Research is a systematic process of asking and answering questions.
-
Research involves procedures, steps to follow for a solution, and empirical evidence (observations and descriptions).
-
Research is objective, logical, cyclic, and requires courage and patience.
-
Steps in Research
- Question: A question needing an answer.
- Hypothesis: A tentative solution (as no evidence exists).
- Literature Review: Review of existing solutions to see if they answer the question or need revision or discarding.
- Evaluation: Further research.
- Data Gathering: Data is collected for research.
- Data Analysis: Data is analyzed.
- Data Interpretation: Data is interpreted to draw conclusions.
- Hypothesis Support: Support or rejection of the hypothesis, and creation of a new hypothesis, which is self-correcting.
- Scientific Method: Proper observation, experimentation, and interpretation.
Research Types
- Primary research: New data not previously reported.
- Secondary research: Data from other researchers (existing data).
- Basic research: Studying natural phenomena (pure science—e.g., cell study, animal experiments).
- Clinical trials: Testing treatment effectiveness.
Other Information
- Qualitative research: Non-numerical, descriptive (using words).
- Quantitative research: Numerical, non-descriptive (using numbers and statistics). Results are often presented as graphs and tables.
- Qualitative and quantitative research can be mixed.
- Exploratory research: Investigations into new phenomena without definite answers.
- Longitudinal research: Data collection at multiple points in time (following a population's trend).
- Cohort studies: Data collection for a subset (group) over an extended period.
- Cross-sectional research: Data gathering once (e.g., surveys).
