Chapter 1 - Biology
study guide
| Term | Definition |
|---|---|
| Atom | smallest particles that keeps properties of an element |
| Biology | A large range of related topics from biological molecules/biochemistry, cells, plants, wildlife, medical careers, and entire ecosystem |
| Biosphere | all areas of earth with life |
| Cell | the smallest unit of life |
| Community | group of many different organisms all in the same area |
| Control | standard or baseline group not exposed in the experiment |
| Domain | |
| Ecosystem | a community (living thing) and the non-living parts of the area |
| Eukaryote | |
| Evolution | |
| Experiment | Procedure that test a hypothesis |
| Falsifiable | inherently disprovable through observation or experimental |
| Homeostasis | |
| Hypothesis | ask questions/identify a problem |
| Hypothesis-Base Science | Ask questions/identify a problem, and test potential answer or solution. |
| Kingdom (Animalia, Plantae, Fungi, "Protists") | |
| Molecule | form structures that when together form a cell |
| Multicellular | some organisms have many cells |
| Observation | change |
| Organ | tissues combine to form organs |
| Organ system | many organs working together |
| Organelle | an organ |
| Organism | one individual living thing |
| Peer-reviewed manuscript | a paper that been evaluated and critiqued by experts |
| Plasma membrane | Outer boundary of a cell |
| Population | group of organisms all the same species in an area |
| Prokaryote | |
| Science | science is big |
| Scientific Ethics | -ensuring science/research does not cause undue damage to humans, animals, or the environment -ensuring research and communication are free of bias -legal safety, financial consideration -biology research often directly involves living things |
| Scientific method | - Studying the living world by asking questions and seeking science-based responses -usually starts with an observation and a problem to solve - learning about the topic, develop a hypothesis and experiment to test their hypothesis |
| Scientific theory | tested and strongly confirmed explanation, term theory has different meaning in scientific terms |
| Species | organisms of the same type |
| Tissue | cells combine to form tissues (group of similar cells) |
| Unicellular | some organisms consist of single cells |
| Variable | items in the experiments |
| Independent variable | What the researcher can choose/control (can also called the experimental treatment) |
| Level of Treatment | specific values chosen for the independent variable |
| Controlled variable | keeping the same for the experiment |
| Control group | often natural level or zero level, to present a comparison to the experimental level |
| Dependent variable | type of data collecting during an experiment |
