Chapter 1: Life: Chemical, Cellular, and Evolutionary Foundations
- Section 1.1: The Scientific Method
- Section 1.3: The Cell
What is Science?
- A body of knowledge gained through the scientific method.
- Exploration: Making observations, asking questions, reviewing literature.
- Investigation: Forming hypotheses, making predictions, conducting experiments, gathering and interpreting data to build a theory.
- Communication: Discussing experiments, sharing results, publishing papers, participating in conferences, applying science to policy issues.
Observation Practice
- Note observable phenomena.
- Generate possible explanations (“what's going on”?).
- Hypotheses should be testable, objective, and answer "what would happen if the hypothesis is correct".
- Predictions: What would happen if the hypothesis was true.
- Repeat experiments; if results are consistent, it supports the hypothesis; if not, the hypothesis is rejected or revised and experiments will be repeated.
- A theory is a broad explanation supported by many experiments and observations.
Experimental Design
- Observational vs. Controlled Experiments – Manipulated conditions.
- Controlled experiments have multiple groups (almost)
- Control Group does not contain the variable of interest, it's used for comparison.
- Test Group contains the variable of interest.
Spontaneous Generation
- Background: The belief in the 1600s that maggots appeared spontaneously.
- Observations: Flies gather around decaying matter.
- Hypothesis: Maggots come from fly eggs laid on the decaying matter.
- Predictions: Keeping flies away from decaying matter would prevent maggots from appearing.
Experimental Design (Example)
- Control Group: Open jar, maggots appear.
- Test Group (Gauze-covered): No maggots appear even with flies visible.
- Test Group (Sealed): No maggots appear, flies are hindered from getting to the meat.
Biology, the Study of Life
- Defining life: Difficult, instead focus on characteristics.
- Complex spatial organization
- Composed of cells
- Require energy
- Metabolism: Chemical reactions for energy use and maintenance.
- Respond to environment.
- Reproduction.
- Evolution.
- DNA is common to life.
The Cell – Functional Units of Life
- Unicellular organisms (Examples Bacteria, Yeast, etc.).
- Multicellular organisms (Examples Fruit flies, Cheetahs, humans, etc.).
- One cell, vastly diverse structures.
DNA: An Essential Component
- Stores genetic information.
- Central Dogma: DNA → RNA → Protein (replication, transcription, translation).
Cell Types
- Prokaryotic and Eukaryotic.
- Commonalities include a plasma membrane that encloses the cytoplasm.
- Eukaryotic cells are more complicated, with a nucleus and organelles.
- Prokaryotic cells are only single-celled.
Hypothesis vs. Prediction
- Hypothesis: a possible explanation
- Prediction: what would be observed if the hypothesis were correct
