Answers

1
What is true regarding the experiment showing O₂ formed at different light intensities?
2 & 3 are both true
O2 production is the dependent variable
Light intensity is the dependent variable
Light intensity is the independent variable
2
Differentiation
all of the above
is controlled by DNA
occurs when certain genes turn on or off
is the difference between kidney cells and liver cells
3
All of the following is true regarding a light compound microscope except
Glass lenses are used for focusing
Resolution and magnification might differ
Electrons are used to view the specimen
Total magnification is 1000 x
4
