BIOL 1201 Lecture : Lecture 1
Document Summary
Science- systematic knowledge of the natural world through observation and experimentation. Discovery- conclusion based on induction (from general premises we extrapolate specific results) Hypothesis-based- conclusion based on deductions (from specific observations we create generalizations. Hypothesis testing: formulation from observation, test by experimentation and observation, document results (collect data, submit results and conclusions for peer review (journal) Similarities in organisms: morphological, anatomical, biochemical, molecular characteristics. Prokaryotic cells- lack nucleus and organelles, except for ribosomes, relatively small (1-10 micrometers) Eukaryotic cells- dna package in nucleus, with diverse organelles, relatively large (10-100 micrometers) Aerobic- cells require oxygen to break down carbon compounds and produce energy. Anaerobic- cells break down compounds and produce energy in the absence of oxygen (facultative and obligate cell) Autotrophic- organisms that convert light energy into chemical energy.
