Evidence-Based Biology: Understand that biology relies on evidence and the scientific method for learning, involving hypothesis testing.
Chemical Bonding and Macromolecules: Distinguish between different types of chemical bonds and recognize the major macromolecules in cells.
Cell Biology: Describe fundamental cell biology, including structures, functions, prokaryotic and eukaryotic cell differences, and basic cellular processes.
Genetic Inheritance: Explain inheritance mechanisms of genetic information in DNA, including mitosis, meiosis, cell cycle significance, chromosome nature, and Mendelian genetics.
Flow of Genetic Information: Describe the flow of genetic information in a cell via DNA → RNA → protein.
Information Changes: Understand how changes in DNA can impact cells and organisms.
Theory of Evolution: Comprehend how evolution applies to life and human interests.

I. Review of Objectives for Chapter 1II. What is Biology?

Characteristics of lifeIII. Biology and the Scientific MethodIV. 5 Themes of Biology

Define biology and summarize the 7 properties of life.
List core steps in the scientific method and define key terms: hypothesis, prediction, experimental group, control group, conclusion.
Identify and describe the major themes of biology and the levels of biological organization from smallest to largest.
Explain the relationship between evolution, unity, and diversity of life.
Identify the 3 domains of living organisms and their cell types.

Biology is the scientific study of life and encompasses a vast diversity of life forms and interactions with their environments.
Life spans a range of organization from molecular to global, including individual organisms, their communities, and ecosystems.

Organization: Structured levels of biological organization.
Metabolism: Chemical reactions for energy storage and release.
Homeostasis: Maintenance of a constant internal environment despite external changes.
Growth: Regulated growth in size.
Reproduction: Capability of producing new organisms, either sexually or asexually.
Response to Stimuli: Ability to respond to environmental changes.
Evolution: Changes in the genetic makeup of populations over time.

Nonliving Traits: Lack cellular structure, inability to reproduce independently, unclear metabolism.
Living Traits: Reproduction when inside a host, organized structure, exhibit evolutionary changes.

Definition: An inquiry-based process for understanding the natural world involving logical problem-solving steps.
Core Steps:
1. Make observations.
2. Ask a question.
3. Form a hypothesis and make predictions.
4. Test predictions through experiments.
5. Use results to form new hypotheses (iterative process).

Builds on existing knowledge, allowing for new discoveries and corrections to established findings through empirical evidence.
Tests hypotheses by manipulating only one variable while keeping others constant.

Independent Variable: Variable manipulated by the researcher.
Dependent Variable: Response observed due to changes in the independent variable.
Experimental vs. Control Groups: Experimental groups experience the change; control groups are kept constant.

Examines how independent variables affect dependent variables and presents data visually to support conclusions.

Data must be summarized, compared with existing research, and used to guide future inquiries.

Observations of varying coat colors in two mouse populations from different habitats lead to the question: how do these colors relate to their environment?
A hypothesis claims that color adaptations serve as camouflage against predators.

Levels of Organization: Understanding hierarchical structure from atoms to biosphere.
Information Flow, Exchange, & Storage: Transmission of genetic material and signaling within organisms.
Energy & Matter Transfer: Transformative processes involving energy dynamics in ecosystems.
Interactions: Relationships affecting organisms and environments, influencing short-term and long-term population evolution.
Evolution: Central theme emphasizing genetic change and diversity through mechanisms like natural selection.

Order of organization: Atom → Molecule → Organelle → Cell → Tissue → Organ → Organ System → Organism → Population → Community → Ecosystem → Biosphere.

Prokaryotic Cells: Smaller, without organelles, unicellular, found in domains Archaea and Bacteria.
Eukaryotic Cells: Larger, possess organelles, can be unicellular (protists) or multicellular (plants, fungi, animals) in domain Eukarya.

Not a random process but rather through natural selection acting on genetic variations; reiterates the distinction between hypotheses, theories, and facts in scientific discourse.
