A

The study of organisms interacting with each other and with the environment.

18
Q

What is an Ecosystem?

A

Communities of living species and their physical environment.

19
Q

What is the natural selection theory?

A

As animals reproduce, the ones with the weaker genes will die out and not have their genes passes on while the ones with the strongest genes with pass their genes on more

20
Q

What is the adaption theory?

A

Needed traits for environment are developed through evolution.

21
Q

Scientific method

A

An organized approach to learn how the natural world works

22
Q

Observation

A

Is the act of perceiving a natural occurrence that causes someone to pose a question

23
Q

Hypothesis

A

A proposed explanation for the way a particular aspect of the natural world functions

24
Q

Prediction

A

a statement that forecasts what would happen in a test situation if the hypothesis were true

25
Q

Experiment

A

Something to test a hypothesis and its predictions

26
Q

Control Group

A

A group that provides a normal standard against which the biologists can compare results of the experimental group

27
Q

Experimental Group

A

A group that is the same as the control group but has an independent variable

28
Q

Independent variable

A

The factor the experimenter manipulates

29
Q

Dependent Variable

A

The variable or part of the experiment that changes in response to the independent variable

30
Q

Peer Review

A

Review by a person who knows a lot about the subject that is being written about and edits the paper anonymously

31
Q

What are the six steps of the scientific method in order?

A

1) Observation
2) Hypothesis

A

an educated guess

33
Q

Why does an experiment need to be organized?

A

So that it can be repeated

34
Q

What is the independent variable and what axis is it on in a graph?

A

The independent variable is the variable the experimenter manipulates and is on the x axis

35
Q

What is the dependent variable and what axis is it on in a graph?
