| What is the difference between quantitative data and qualitative data? |
|
Definition
| Quantitative data has to do with numbers and measurements. For example, height and mass would be considered quantitative data.
Qualitative data refers to any data that does not have to do with numbers. Color, smell, and shape are examples of qualitative data. |

|
Term
| Define: spontaneous generation |
|
Definition
| The belief that life could arise from nonliving matter. This belief was tested and proved untrue. |
|
|
Term
| What is a controlled experiment? How many variables can be accurately tested at a time? |
|
Definition
| A controlled experiment is an experiment in which a hypothesis is tested by changing one variable at a time. All of the other variables are kept unchanged (conrolled). |
|
|
Term
| Define: manipulated variable |
|
Definition
| The variable in an experiment that is deliberately changed. |
|
|
Term
| Define: responding variable |
|
Definition
| The variable in an experiment that responds to changes in the manipulated variable. |
|
|
Term
|
Definition
| A hypothesis that builds up an incredible amount of evidence to support it. |
|
|
Term
| What is the difference between a hypothesis and a theory? |
|
Definition
| A hypothesis is something that will be tested in an experiment.
A theory is a hypothesis that has been proven to be correct through multiple experiments and plenty of evidence. It's something that has not yet been proved incorrect. |

Term
|
Definition
| The combination of chemical reactions through which an organism builds up or breaks down materials as it carries out its life processes. |
|
|
Term
|

| What is the difference between external and internal stimuli? |
|
Definition

Term
| What is the difference between evolution and growing? |
|
Definition
| Evolution occurs over hundreds or thousands of years within a part of or a whole species.
Growing and developing occurs over the lifetime of one organism. |
|
|
Term
| What are the levels of biology in which life can be studied? |
|
Definition
| Biospheres -> Communities -> Populations -> Organisms -> Cells -> Molecules
Example: The rainforest could be a biosphere; the community could be a certain area of the rainforest, by a lake and the trees surrounding it, containing different species of fish, birds, and other animals; the population could be one species of fish in the lake; the organism could be one specific fish; the cells would make the fish; the molecules would make up the cells. |
