1. Cells and organization
2. Energy use & Metabolism
3. Responses to environnent changes
4. Regulation and homeostasis
5. Growth and Development
7. Biological Evolution
Hierarchal categorization of living matter from atoms to the biosphere and explain the unique features (Ten different levels of organization)
1. Atoms 2. Molecules and Macromolecules 3. Cells 4. Tissues 5. Organs 6. Organisms 7. Population 8. Community 9. Ecosystem 10. Biosphere
Three domains of life
Bacteria, Archaea, Eukarya
refers to the complete genetic composition of an organism
Constructs general propositions from specific examples
reasoning in which a conclusion is reached by stating a general principle and then applying that principle to a specific case (The sun rises every morning; therefore, the sun will rise on Tuesday morning.)
Hypothesis Testing Process
3. Hypothesis/ Prediction
idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
Observations that are made using your senses and descriptions. Information that is hard to measure, count, or describe in numbers. It describes the qualities of something.
Observations that give a quantity or amount. Information can be expressed in numbers. It is something that can be counted or measured.
Which of the three domains are not made of prokaryotic cells?
Eukarya, humans are classified as this.
Results in change in the genetic makeup of populations over time.
Define negative and positive feedback; recognize examples of each
Negative: maintain a set point (body temperature)
Positive: accelerates a process (blood clotting, birth)
environment can determine which organisms survive (predation, food competition, temperature..)
Unicellular, single outer membrane
2 Domains early on = Bacteria & Archaea
Outer membrane + internal membranes at organelles
Nucleus = organelle with most genetic information
Came from group of Archaea
Enfolded membrane - cellular compartments
Domain is Eukarya
