| Know the Coreolis Affect | It doesn't allow the wind to move straight across the earth |
| How do waves differ from out in the middle of the ocean and the waves towards the shore | The shallowness from the shore causes friction from the sand causing the waves to break and crash; out in the middle of the ocean the waves form a circular motion going in circles |
| Heterotrophs | Don't make their own food |
| Autotrophs | Make their own food |
| What is a common way of making ones own food? | Photosynthesis |
| If photosynthesis is not an option what else can be used to make food? | chemosythesis |
| Would you expect to find a large amount of heterotrophs in a place with little sunlight? | No, because they have to rely on autotrophs for food and autotrophs rely on photosynthesis |
| An angle fish is an example of what? | poikilotherm and an ectotherm |
| A shark is an example of what? | poikilotherm and an endotherm |
| A dolphin is an example of what? | homeotherm and an endotherm |
| Why is drinking salt water bad for you? | It tries to equalize the amount of salt content in your body so it sends out even more water from your cells making you more dehydrated |
| Why does a strawberry sweat? | Sugar is more concentrated on the outside so it sends water out to equalize; osmosis |
| Diffusion | travels from an area of high concentration to an area of lower concentration |
| Diatoms | used in toothpaste |
| Brown algae | Algin - used to hold things together (stays mixed together) EX: pudding |
| Relationship between a fungus and algae | Fungus provides support and algae provides the food |
| Why does sea grass not need big showy flowers for reproduction? | The currents take the gametes along |
