Introduction: Overview of biology
I. What is biology ?
II. Definition of life:
Cellular organization
Growth and development
Regulation of metabolic processes
Homeostasis
Reproduction
Heredity
III. Transmission of information:
1. DNA molecules
Genetic information

2.Chemical & electrical signal
Hormon
Nerve cells
IV. Evolution: primary unifying concept

Species adaptation
Natural selection
Selective pressure
V. Hierarchi of biological organization
1. Organismal level of organization
Atoms and molecules
Macromolecules (Biomolecules)
Subcelluar organells
Cells
Tissues
Organs
Organ system
Organisms
2.Ecological level of organization
Population
Community
Ecosystem
Biosphere
VI. Biological diversity
Naming organisms (binomial system)
Scientific names:
Bahasa Latin atau dilatinkan
Terdiri dari dua kata
Kata pertama: nama Genus
Kata ke-dua : penunjuk spesies
Contoh:
Homo sapiens
Oryza sativa
Columba livia
Mycobacterium tuberculosis
Rhyzopus oligosporus
Taxonomic hierarchical of classification
Domain
Kingdom
Phylum
Classis
Ordo
Familia
Genus
Species
Txonomic hierarchical of classification
Kingdoms of life:
Three domains: Six Kingdoms:
I. Archaea 1. Archaea
II. Bacteria 2. Bacteria
III.Eukarya 3. Protista
4. Fungi
5. Plantae
6. Animalia

VII. Life requires energy supply
1. Energy flows through organisms
Metabolism: catabolism & anabolism

2.Energy flows through ecosystem
Energy flows through food chains
Scientific Method
VIII. Biology as a science (Scientific method)

Scientific thinking process
Scientific observation and question
Hypothesis: possible explanation to account for observation
Scientific experiments: testing hypothesis
Results of experiments
Scientific theory: e.g. Evolutionary theory
Ethical dimensions of science
