Random
which axis has the dependent variable
dependent variable=y axis
why do many experiments make use of control groups
something to compare to
what element makes all things "organic"?
carbon
how do you estimate the size of a cell or cell structure when using a microscope?
consider magnification and original size
why would it be a bad idea to do this?
could kill fish
how do you determine the magnification of the field of view for a microscope?
power lens*power of objective=magnification
what are the characteristics of a good experiment?
many test, all parts of an experiment present
what are some of the ways that living things use energy
photosynthesis , cellular respiration
what do you adjust first on a microscope?
course adjustment
the dependent variable?
dependent= breathing rate
what would be a good control for this experiment?
temperature stays the same and measure
what is the difference between an inference and an prediction?
inference= based on observation; prediction= is a hypothesis
what are ways that cells maintain homeostasis
sweating panting
what you then adjust when on the highest power?
fine adjustment
what happens to breathing rate with increase in temperature?
increases
decreased
:(
what are the difference between an independent and dependent variable?
independent variable=thing you test or change; dependent variable=thing you measure
what is a buffer?
buffers are solutions that prevent sharp changes
what is the independent variable?
independent= temperature
how do you think would happen if you raised the temperature even more?
increase in breathing rate
what is the function of the cell membrane?
semi permeable allowing allowing some molecules in and some out of the cell
which axis has the independent variable?
independent variable= x axis
