Term
| Why do we have a null and alternative hypothesis? |
|
Definition
For comparrison.
Null: The rats will not gain weight on the enriched food.
Alternative: The rats will gain weight on the enriched food. |
|
|
Term
|
Definition
Breaks a complex process down to its simpler parts.
Small components, not the whole story. |
|
|
Term
|
Definition
Focus on emergent properties that can't be understood by looking at simpler parts.
Big picture. Ex: Nerve impulses |

|
Term
| What is the scientific theory? |
|
Definition
| A body of interconnected concepts that is supported by much experimental evidence and specific reasoning and aims to express ideas of which we are most certain. |

|
|
Term
| What is the molecular basis of inheritance? |
|
Definition

|
Definition
|
|
Term
| What is the nonequillibrium state? |
|
Definition
| Living systems are open systems that need a constant supply of energy. They have self-organizing properties at different levels and emergent properties from molecules, cells, and individuals. |
|
|
Term
| What is evolutionary change? |
|
Definition
| The diversity of life is the result of evolutionary change over long periods of time (3.5 billion years). |
