why do many experiments make use of a control group?
something to compare
how do you determine the magnification of the field of view for a microscope ?
power of lens
What is the independent variable?
The dependent variable?
Independent variable=Temperature
Dependent variable=Breathing rate
What is the definition of Starch?
A macromolecule of sugar used short term or quick energy?
which reaction(s) requires or stores energy ?
all require some form of energy
What are the characteristics of a good experiments?
Many test, all parts of an experiment presents
what happens to the diameter of the field of view when you change from low to high ?
less to high magnification
What is the best type of graph for this data?
Line= Shows trends
whats the definition of Cellulose?
A macromolecule of sugar used to make cell walls in plants?
which reaction(s) release energy (ATP) ?
all release some form of energy mostly B and C
What is the definition of inference?
Inference= based on observations
how do you estimate the size of a cell or cell structure when using a microscope ?
consider magnification and original size
What happens to breathing rate with increase temperature?
Whats the definition of Enzymes?
Proteins used to lower activation energy to cause chemical reactions to occur?
which reaction releases the most energy ?
B because it uses oxygen
What is the definition of Independent variable?
Independent variable= things you test or change
what do you adjust first on a microscope ?
course adjustment
What would be a good control for this experiment?
Temperature stays the same and measure.
Whats the definition of DNA?
Genetic code of life used in replication and transcription
Which reaction requires chlorophyll ?
A, chlorophyll traps light energy for photosynthesis
Which axis has the dependent variable?
Dependent variable= the Y axis
what do you adjust on a microscope when on the highest power ?
fine adjustment
What do you think would happen if you raised the temperature even more?
Increases in breathing
Whats the definition of RNA?
Genetic code of life used in transcription and translation?
which reaction requires light ?
A, light is required for light dependent reaction for photosynthesis
