what is one goal in science?

science cannot provide answer for all questions 

100

What does the dependent Variable represent?

the affect by other factors, what I'm measuring 

100

what are some characteristics of life?

-Responds to the environment 

-grows and develops

made of cells 

100

what is a chemical reaction?

the change of one substance into another shown by chemical equation 

100

what is activation energy?

the energy required to start a chemical reaction

200

what is the order of the scientific method? 

1.observation

2.question 

3.hypothesis 

4.test/planning

5.experiment 

6.results

200
what does the independent variable represent? 

the changing thing by the experiment, what I change 

200

what is cell theory? 

The living things are made of cells


200

what are products?

this is what it creates 

200

what is metabolism?

the sun of all the reactions within an organism 

300

what is science? 

the way of gaining knowledge about the natural world.

300

what is does the constant represent? 

the unchanged in the experiment 

300

what is gene theory? 

characteristics are transformed from parents to offspring with chromosomes

300

what is reticence? 

the starting of an reaction 

300

What are metabolic reactions? 

exothermic reactions which break down large molecules and supply energy

400

what is the scientific law?

the statement that cannot change under certain natural conditions. 

The law of gravity 


400

what does the control group represent? 

this is used for comparison

400

what are some examples of living things?

organisms, symbiosis, competition 

400

what is conservation of matter? 

Matter cannot be created or destroyed under normal conditions 

400

what are anabolism reactions? 

endothermic reactions which build up large molecules and require energy

500

what is "models"?

models show what's happening

500

what would be the dependent variable in this scenario? 

the amount of fertilizer is given to the plants, this experiment is testing how different fertilizers levels affect the plant growth.

The dependent variable is the fertilizer amount.

500

what is evolution? 

the change over time 

500

what is a biochemical reactions?

this means chemical reactions that occur within living things that are inside cells 

500

what is a enzyme function?

to speed up reactions in cells, without them most life would die
