USU BIOL 1010
Biology 1010 Exam 1
| Question | Answer |
|---|---|
| 7 Properties of Life | 1. Cells and Organization 2. Energy Use and Metabolism 3. Response to Environmental Change (Elasticity) 4. Regulation and Homeostasis 5. Growth and Development 6. Reproduction 7. Biological Evolution |
| Steven J. Gould - Evolution Repeatability | Vanishingly small chance that evolution would be able to repeat itself or anything like it. There is no direction or progression in evolution. |
| Johnathan Loso - Evolution Repeatability | Studied lizards. Produce highly similar evolutionary outcomes. |
| Richard Lenski - Evolution Repeatability | Studied bacteria. Turned out sometimes the same. |
| Steps of Speciation | 1. Populations become genetically isolated from each other (allopatric or sympatric) 2. Populations diverge genetically 3. Reproductive isolating mechanisms evolve, keeping populations independent if/when they come back together. |
| Examples of reproductive isolating mechanisms | Mate Preference Lack of fit between sexual organs Timing of mating Hybrid Sterility |
| Allopatric vs. Sympatric Isolation | Allopatric - block to gene flow is a geographic barrier Sympatric - origin of a new species without geographic isolation |
| How Biologists Predict Speciation | Use models of speciation to make predictions and then check these predictions against observations of the natural world and the outcomes of experience. |
| Ecosystem Ecology Definition | The study of energy flow and cycling of chemicals among various biotic and abiotic factors in an ecosystem |
| Biotic vs. Abiotic Factors | Biotic - all of the organisms in that area Abiotic - environments nonliving components; physical and chemical (temperature, light, water, etc.) |
| ________ is recycled rapidly and primarily through atmosphere. ________ is cycled through the rock cycle slowly by rock formation and weathering. | Carbon Phosphorous |
| Latitude Diversity Gradient | There is high diversity near the equator and low diversity as you get closer to the poles. |
| 3 Hypotheses Explaining LDG | "cradle hypothesis" - tropics are where species tend to be born "museum hypothesis" - tropics harbor species that would go extinct elsewhere "destination hypothesis" - species somehow just end up there |
| Evidences for Evolution | 1. Fossil Record 2. Biogeography 3. Documentation of Natural Selection in Action 4. Anatomical, embryological, and molecular homologies |
| Origin of Life: When? | ~4 billion years ago when Earth's atmosphere had little to no free oxygen. |
| Origin of Life: Where? | Possibly near deep sea hydrothermal vents |
| Origin of Life: How? | 1. Simple organic molecules were formed 2. Replication evolved and underwent natural selection 3. Became enclosed with cell membrane 4. Evolved new metabolic processes 5. Multicellularity evolved |
| 3 Domains | Eukaryota, Bacteria, Archaea |
| Common Misconception About Evolution | Evolution is the theory about the origin of life |
| Prokaryotes | Bacteria and Archaea |
