Unit 1 Biology Kloet
| Question | Answer |
|---|---|
| Definition of Biology: | The study of life (bio = life) (logy = study of) |
| What is biology relevant to? | Medicine, environment, personal choices |
| What is the Scientific Method? | The process that scientist use to find knowledge about the "physical" world using logical problem solving steps which can be repeated by others for further investigation . |
| Order of scientific method: | Problem, Observation, Hypothesis, Prediction, Experiment, Theory |
| Problem: | A question about an observation. |
| Observation: | An experience of perception through the senses. |
| Hypothesis: | A testable answer for an observation |
| Prediction: | What you expect to happen when you test the hypothesis |
| Experiment: | The test of a hypothesis that can be repeated. |
| Control Group: | The untreated group used for comparison |
| Experimental Group: | The group that receives treatment |
| Constants: | Remain the same |
| Independent | the factor that is changed (treatment) x-asis |
| Dependent | responds to changes (measurable) y-axis |
| Theory: | A scientific principle based on many tested hypotheses but can always change if new info is available. |
| Four Unifying Themes in Biology: | Structure and Function, Homeostasis, Evolution, and Systems. |
| Structure and Function: | shapes and how they work |
| Homeostasis: | Balance with internal and external environments |
| Evolution: | inherited change over time |
| Systems: | Organized group of related parts that interact to form a whole |
| Tools used in Biology: | Light Microscope, MRI, SEM, TEM |
| Endotherm: | Organisms that are able to regulate their temp from the inside |
| Archaeology: | Study of something old and ancient |
| Inference: | To make an educated guess. (ex. if there were mud puddles, you would infer that it rained) |
| Linneaus | Botanist who developed system of binomial nomenclature |
| Aristotle | Person who came up with first system |
| Scientific Names | Genus species (underlined) |
| Characteristics/ Properties of Life | Cells, Energy, Response/Homeostasis, DNA-heredity |
| Taxonomic Order | Kingdom, Phylum, Class, Order, Family, Genus, Species |
| Human Taxonomy | Animalia, Chordata, Mammalia, Primates, Huminidae, Homo, Sapien |
| 6 Kingdoms | Animalia, Plantae, Fungi, Protista, Archaea, Bacteria |
| Which Kingdoms are Multicellular | Animalia, Plantae, and Fungi |
| Which Kingdom is unicellular | Protista |
| Which Kingdoms are Eukaryotic | Animalia, Plantae, and Protista |
| Which Kingdoms are Prokaryotic | Archaea and Bacteria |
| Eukaryotic: | nucleus with DNA |
| Prokaryotic: | No nucleus |
| Adaptation: | Inherited trait that gives advantage to individual organisms |
| Ecosystem: | Physical environment with diff. species that interact with each other and with nonliving things |
| Qualitative Data | Senses |
| Quantitative Data | What you can measure |
| Biotechnology is based on | living things and biological processes |
| A Transgenic organism is one that | has been developed through genetic manipulation |
| Gene | segment of DNA that stores info |
| Genomics | The study and comparison of genomes both within and across species |
