| Question | Answer |
|---|---|
| Nutrition | activity by which an organism takes nutrients from its environment and prepares it for its use |
| What are the three parts of nutrition | 1.Ingestion-taking in food 2.Digestion-breaking down food so it can be used by organisms 3.Egestion- removal of undigested or indegestiable food materials |
| transport | the process by which substances enter and leave cells and become distributeds within cells. Simple organisms- materials are exchanged directly through the environment. Complex organisms- the circulatory system transports materials |
| Respiration | a series of chemical reactions that release energy from nutrients |
| excretion | removing excess/harmful material from the body (i.e. urine, throw up) |
| Synthesis | building complex substances out of smaller ones. i.e. our cells build melanin, a protein which gives our skin its color |
| Regulation | responding to changes in the environment in order to maintain a stable balance. i.e. our body sweats to keep itself at 98.6 degrees F |
| Growth | an increase in size and number of cells |
| reproduction | creating new organisms, asexual- one parent(starfish, virus)sexual- two parents(humans) |
| Metabolism | all the chemical processes by which an organism carries on its life functions includes breaking down and building substances |
| Homeostasis | Organism controls and regulates all the chemical processes in order to maintain a stable internal environment. If disrupted in major way,you die. Regulation is maintaning homeostasis` |
