5 To Stay Alive! P2
The 5 characteristics of Life Scenarios
| Question | Answer |
|---|---|
| When bacteria or viruses that can make you ill get into your body, your lymphatic system kicks in. It works to fight the infection before it has the opportunity to make you sick, ensuring that you remain healthy. | Homeostasis |
| The heart can sense changes in the blood pressure, causing it to send signals to the brain, which then sends back signals telling the heart how to respond. | Homeostasis |
| The smallest unit of organization of a living thing is the cell. | Cellular Organization |
| For life to continue, organisms must replace themselves. | Reproduction |
| This is essential for the continuation of an organism's species. | Reproduction |
| Over time, these organisms grow and take on the characteristics of their species. | Metabolism |
| All of the changes that take place during the life of an organism are known as its development. | Metabolism |
| Some organisms obtain energy from the foods they eat or, in the case of plants and several other types of organisms, the foods that they produce. | Metabolism |
| External environmental factors act as stimuli and can cause a response from living things. Organisms need to respond to the changes in order to stay alive and healthy. | Homeostasis |
| Adjustments to internal changes help organisms maintain a stable internal environment. | Homeostasis |
| You have a “thermostat” in your brain that reacts whenever your body temperature varies slightly from 37°C (about 98.6°F). | Homeostasis |
| Cells that have too much water in them bloat and can even blow up. Cells with too little water can end up shrinking. Your body maintains a proper water balance so that neither of these situations occurs. | Homeostasis |
| Children resemble their parents | Heredity |
| An organism made up of many cells (multicellular) | Cellular Organization |
| An organism made up of only one cell (unicellular) | Cellular Organization |
| Two different penguins contribute genetic information to produce offspring | Reproduction |
| An organism takes in food that is broken down to release energy in its body | Metabolism |
| A students is forced to run the mile in gym class. After running for 2 minutes, the student begins to perspire as their body heats up during the exercise | Homeostasis |
