Document Summary
Nature and reality encompass the entire universe not just the human condition. They are approached as objectively as possible through input from our senses. Robert hooke first microscope 30x 1665. Anton van leeuwenhock first to view single celled organisms (paramecium) Many complex questions cannot be studied using the scientific methodology (global warming) Predominantly carbon and water based: most of the o2 and h2 is in the form of water (h2o=70% of our body weight, carbon provides the backbone for our constituent organic molecule (proteins, nucleic acids, carbs, lipids) Acquires energy and materials from its surroundings. Not regarded as being alive they are parasitic paralife forms. Acquires energy and material from its surroundings. Evolves over many generations through natural selection. Living organisms operate across many levels of hierarchical organization from molecular to ecosystem. Each level has emergent properties not found at lower levels, i. e. , populations have attributes lacking in individual organisms. Water: necessary for life (mobility, nutrients)
