Introduction To Biological Concepts and Research
| 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 |
