BIO198 Module 1
| Question | Answer |
|---|---|
| Definition of Biology | The scientific study of life - (scientific study: collection of knowledge and process of gaining that knowledge, life: characteristics of living things.) |
| Characteristics of living organisms that define "life" | 1. Acquire materials and energy 2. Organize structure 3. Maintain homeostasis 4. Reproduce 5. Sense and Respond to the environment |
| 1. Acquire Materials and Energy | Absorb nutrients from the sun or soil, gather food and water |
| 2. Organize structure | Birds make bird nests, homes |
| 3. Maintain Homeostasis | Regulating constant internal conditions |
| 4. Reproduce | Have offspring or produce seeds |
| 5. Sense and Respond to the Environment | Feels temp, hibernates during winter, seeks shelter during storm |
| What is biological evolution? | The change in the genetic make up (heritable characteristics within a population) of a population over time. |
| The Biological Hierarchy | a concept map that shows the relationship between various levels of life. atom, molecule, cells, tissue, organ, organ system, organism, population, community, ecosystem, biosphere |
| Atom | The smallest level on the biological hierarchy. Fundamental building block of matter, smallest unit of an element. Ex. Nitrogen atom |
| Molecule | Second smallest level, Two or more atoms held together by chemical bonds Ex. amino acid |
| Cells | fundamental unit of all living organisms, made up of water, ions, and various molecules. Smallest form of life Ex. Cardiovascular muscle cell |
| Tissue | group of cells that have related structures and functions Ex. Cardiovascular tissue |
| Organ | multiple types of tissue that work together to carry out a function Ex. heart |
| Organism | individual living thing, can be single cell, or multi-cell Ex. Bison |
| Population | all individuals of a single species living in a specific area Ex. Bison population |
| Community | all populations living within a specific area Ex. Prairie, animal, plant, fungus, etc |
| Ecosystem | multiple communities and their non living environment |
| Biosphere | all ecosystems on earth Ex. life on earth |
| Why is evolution an important unifying principle for biologists? | Evolution explains how diversity of life has come about. Evolutionary relationships can explain many of the similarities between living organisms |
| Organ system | system made up of multiple organs that function together Ex. Cardiovascular system |
| Scientific hypothesis | A potential explanation based on known facts that can be testable (testable explanation) |
| What is the purpose of the scientific method? | to acquire knowledge specifically about living organisms, the process by which scientists make observations, formulate potential explanations and test possible explanations |
| Scientific theory | a general set of principles explaining an aspect of the natural world which has been repeatedly tested without being disproven |
| What is a difference between hypothesis and theory? | A theory has not been disproven a hypothesis can be disproven |
| What are the two ways you can test a hypothesis? | Observational (not manipulated) and Experimentation (manipulated conditions) |
| Scientific Method | 1. Observations and data 2. Formulate hypothesis 3. Test hypothesis 4. New data 5. Conclusions |
