| What are the three subatomic particles? | protons(p+), neutrons (+-), and electrons (e-) |
| How does your body work to maintain homeostasis of temperature when you're hot? | sweat, heart rate speeds up, respiratory rate speeds up, blood vessels dilated and move to the surface |
| How does your body work to maintain homeostasis of temperature when you're cold? | shiver, heart rate slows down, respiratory rate slows down, blood vessels contract and move away from the surface |
| What do all living things require? | energy |
| What is energy? | the ability to cause change or do work |
| What can Autotrophs (producers) do that heterotrophs can't? | make their own food |
| What can Heterotrophs (consumers) not do? | make their own food |
| What are the characteristics of life? | cellular, metabolism, heredity, homeostasis, reproduction, responsiveness, growth and development |
| Describe this Characteristic of life. Cellular | all living things are made up of cells |
| Describe this Characteristic of life. Metabolism | all living things need energy |
| Describe this Characteristic of life. Heredity | all living things contain DNA and pass it to offspring |
| Describe this Characteristic of life. Homeostasis | cells function best in a small range of conditions...temp., acidity, sugar levels, etc |
| Describe this Characteristic of life. Reproduction | all living things reproduce |
| Describe this Characteristic of life. Responsiveness | all living things respond to their environment/stimuli |
| Describe this Characteristic of life. Growth and development | all living things change in shape, size, and structure |
| What is an ecosystem made up of? | community of organisms + their physical environment |
| What is natural selection? | survival of the fittest (you don't adapt, you don't survive) |

| What is Quantitative data? | numeric measurements. (ex. the dolphin body fat ranged from 4-5%. There were 12 dolphins.) |
| What is Qualitative data? | descriptions in words. (ex. the dolphins ranged in color from gray to white. The dolphins are engaged in play and seemed happy.) |
| When/why do theories change? | because new information is obtained. Typically due to advances in technology. |

| What are the two types of electron microscopes? | TEM- Transmission Electron Microscope (2D, artificial coloring) SEM- Scanning Electron Microscope (3D,, artificial coloring) |
| What is scanning tunneling? | very expensive and very powerful scope that uses needle like probes to view living things 3-dimensionally |
| What are X-rays? | imaging method used to view hard tissue |
| What are MRI's? | Magnetic Resonance Imaging- device used to view soft tissues. uses a strong magnetic field to produce a cross-section image. |
