This is the chapter 1.1 and 1.2 biology review from the Glencoe textbook.
| Question | Answer |
|---|---|
| What does biology mean? | It is the study of living organisms. |
| What does science mean? | It is the process of thinking and learning about what's around us. |
| What is an organism? | It is an individual life form that is a living thing. |
| What do organisms include? | They include things like bacteria, protists, fungi, plants, and animals. |
| What are 6 characteristics that all living things share? | 1. They are made out of units called cells. 2. They can reproduce. 3. They have a genetic code. (DNA and RNA) 4. They can grow and develop. 5. They obtain and use energy/materials. 6. They respond to their environments. |
| what are the other 2 characteristics that all living things share? | 7. They maintain a stable internal environment. 8. They change over time. (they evolve) |
| True or false: Cells are the smallest unit of life on Earth. | True |
| True or false: Only some living things are made out of cells. | False, all living things are made out of cells. |
| What is another name for cells? | "The building blocks of life". |
| What is the difference between a multicellular organism and a unicellular one? | A unicellular organism only has 1 alive cell while a multicellular organism is made up of multiple living cells. |
| What are the 2 types of reproduction? | They are asexual (a single organism/cell dividing) and sexual (involves 2 parents). |
| True or false: All organisms use the universal genetic code and it is the same system for all living things. | True. |
| What is the difference between growth and development? | Growth means an addition of or physical increase in size because of cell division/enlargement. However, development happens when natural changes occur during an organism's lifetime.(puberty) |
| What is the difference between autotrophs and heterotrophs? | Autotrophs make their own food like plants and heterotrophs consume other organisms for their food like animals. Heterotrophs can't make their own food like autotrophs do. |
| What is stimuli? | It is anything that triggers a physical or behavioral change like a response. |
| What is homeostasis? | It is how something is kept at body temperature to retain the equilibrium in the body such as shivering when cold, sweating when hot, etc. |
| True or false: do groups of organisms change overtime for survival with changing environments? | True. |
| What is the scientific method? | It is the system of asking questions, developing explanations, and testing these explanations in the natural world. |
| What are the steps of the scientific method? | 1. Observe 2. Make a hypothesis 3. Experiment 4. Record and analyze data 5. Draw conclusions and report |
| What is a hypothesis? | It is a proposed explanation based on certain events based on the evidence. |
| What must a hypothesis be? | It must be testable. |
| What are hypotheses commonly written as? | They can be written as if...then statements. |
| What is the scientific definition of an experiment? | It is a planned procedure to test the hypothesis. |
| What are the two groups required for an experiment? | They are the control group (used for comparison and not changed at all) and the experimental group. (the manipulated/tested group) |
| What is an independent variable? | It is the factor that the experimenter changes to see what happens or factor that is changed in order to observe what happens, Valid experiments only have 1 independent variable. |
| What are controlled variables? | They are experimenters that keep other factors held constant so they won't affect the outcome. They are not being tested. |
| What is the dependent variable? | The factor that is measured at the end. |
| What is the difference between quantitative and qualitative data? | Quantitative data includes numbers and qualitative data includes descriptions. |
| How can people analyze/record data? | They can use charts, tables, and graphs to make the data easier to understand. |
| True or false: retesting sometimes is needed. | False, retesting is always needed to verify results to get an accurate conclusion. |
| What do scientific theories do? | They summarize a hypothesis that has been supported with repeated testing/lots of evidence. It is the best explanation for something at a given time. |
