1. A View of Life

2. Biology- Study of living things
Level of biological hierarchy
Cell
Tissues
Organs
System
Population
Communities
Ecosystem
Biosphere

3. Living things: Are organized (prior slide)
Acquire materials and energy
Energy
Metabolism
Photosynthesis
homeostasis

4. Living things:
Respond – usually results in movement, ensures survival and carry on daily activities
Reproduce and develop
Reproduce
genes

5. Living things:
Have adaptations – modifications that make an organism suited to its way of life
Natural selection
Species
evolution

6. Biosphere Energy Human population and the environment Biodiversity
In ecosystems, the same nutrients keep cycling through populations and eventually becomes heat
Human population and the environment
Preservation of ecosystems if of primary importance
Biodiversity
Total number and relative abundance of species, variability of genes and different ecosystems

7. Classification of living things
3 domains
Eukarya – eukaryotic
Archaea - prokaryotic
Bacteria – prokaryotic
Kingdoms
Protists – uni/multicellular, various nutrition
Fungus – saprotrophs, molds, mushrooms
Plant – multi, photosynthetic
Animal – multi, heterotrophic

8. Scientific process Observation Hypothesis
Experiments/further observations
prediction
Experiment
Experimental design
Experimental variable – variable being tested
Dependent variable – result or change that occurs
Control
Collecting of data

9. Scientific process Conclusion Scientific theory
Concepts that join together well-supported and related hypotheses
Principle – theories that are generally accepted by an overwhelming number of scientists
law
