Question | Answer |
---|---|
What is Life? | Organized, contains Genetic Materials , Metabolism, Responds to the environment, Reproduces, Change in Population |
Emergent Properties | Something a living things has, but can not be considered living on its own |
Examples of Emergent Properties | Detached foot, hand, tail, eyeball, heart ect. |
Cells | Lowest level of Biological Organization |
Unicellular Organisms | Single celled |
Examples of Unicellular Organisms | Bacteria or Protozoans |
Multicellular Organisms | Made up of Groups of interdependent cells |
Examples of Multicellular Organisms | Plants or Animals |
Population | Groups of organisms of the same kind that live together in the same place |
Community | Group of all the populations of different organism living together in the same place |
Ecosystem | The community and nonliving factors with which it interacts |
Biosphere | All the ecosystems of Earth's waters, crust, and atmosphere |
Deoxyribonucleic Acid (DNA) | Large, double-stranded, helical molecule that contains instructions for building a living organism from simpler molecules |
Genome | DNA of a living organism constitutes (controls actions in cell controlled by protein) |
Genes | specific regions of genome that encode instructions for building RNA and protein |
Proteins | Carry out most of the activities of life, including the synthesis of all other biological molecu;es |
Central Dogma | DNA- RNA (Amino Acid) -Protein |
Metabolism | how body takes in outside food sources breakdowns to get energy |
Photosynthesis | Produces own food |
Cellular Respiration | breaks down biological molecules with oxygen, releasing chemical energy |
Homeostasis | Maintenance of a steady internal condition by responses that compensate for changes in the external environment |
Reproduction | Process in which parents pass on their DNA and produce offspring that resemble them |
