General Biology/Introduction


 * life; evolution; biology;
 * what is life?;
 * order, evolutionary adaptation, regulation, reproduction, response to the environment, growth and development, energy processing;

The study of life reveals common themes

 * here, organization, information, energy and matter, interactions, evolution;
 * levels of biological organization; biosphere; ecosystems, communities, populations, organisms, organs and organ systems, tissues, cells, organelles, molecules,
 * reductionism,
 * emergent properties,
 * systems biology;
 * structure and function;
 * cell; eukaryotic cell; prokaryotic cell;
 * DNA (deoxyribonucleic acid)
 * genes; DNA; DNA encoding; proteins;gene expression;
 * DNA; mRNA; Protein; transcription; translation; protein folding; genomics; proteomics; proteome;
 * bioinformatics;
 * producers; consumers;
 * energy flow; chemical cycling;
 * ecosystem; molecules; organisms; feedback regulation;negative feedback; positive feedback;
 * evolution;

The Core Theme: Evolution accounts for the unity and diversity of life

 * evolution; Theodosius Dobzhansky;
 * Grouping Species;
 * three domains of Bacteria; Archaea; Eukarya;
 * dual nature of unity and diversity;
 * Charles Darwin;
 * On the Origin of Species;
 * descent with modification; natural selection;


 * Darwin developed his theory;
 * evolution; natural selection;
 * the tree of life; natural selection; family tree;

In studying nature, scientists make observations and form and test hypotheses

 * science; inquiry; observation; data; inductive reasoning; hypothesis; sometimes case study;
 * experimental variables and controls;
 * experiment; variables; controlled experiment; independent /dependent variable; theory;
 * science; cooperative approach;
 * cooperation; model organisms; technology;
