Notes

Science as process: The word science is derived from a Latin verb meaning "to know." That is, biology is an ongoing process of learning, not just a list of facts.
Evolution: Evolution is simply how living things evolve, or change, over time. It explains inherited similarities in organisms and causes of variation.
Energy transfer: All organisms perform work as they move, grow, and reproduce and need an energy source to do so. Organisms constantly transfer energy to their surroundings, and vice versa. This transfer involves the conversion of one form of energy into another.
Continuity and change: Organisms reproduce to ensure their species continues. But combining genes also results in variations in offspring.
Relationship of structure to function: Every type of organism has developed parts to adapt to its habitat. Birds have different kinds of beaks, and plants have different kinds of seeds, for example.
Regulation: Also called homeostasis. Cells, animals, and ecosystems work to maintain stable internal conditions, such as body temperature, even when external conditions change.
Interdependence in nature: The flow of energy and cycling of matter are the two processes that determine the relationships between organisms and their surroundings.
Science, technology, and society: Scientific inquiry should consider the ethical and social impact of the research. In other words, scientists must make decisions based on what society should do over what it can do.
