Test Review Topics Flashcards
For the monarch butterfly experiment, what was the independent variable?
This was the manipulated variable - the presence of absence of infection was the IV.
What was the DV in the monarch butterfly experiment?
of eggs laid
What is a hypothesis?
A tentative explanation of observed phenomenon.
Is a hypothesis a if, then statement?
NO, that is the predictive statement. The hypothesis can be inserted in this statement: If (insert hypothesis), then…
What would be the hypothesis and predictive statement for the butterfly experiment?
Infected mothers prefer to lay their eggs on antiparasitic plant. If infected mothers prefer to lay their eggs on antiparasitic plant, then there will be more eggs on antiparasitic plant.
What would be the control group in the butterfly experiment?
The uninfected butterflies.
What is the numerical aperture equation?
What is resolution?
The smallest distance between two points on a specimen that can still be distinguished as two separate entities.
The higher the resolution the smaller the distnace = more detail.
What is field of view and depth of field?
What happens to these if magnification increases?
FOV - circle of light seen in the microscope
DOF - thickness of specimen that may be seen in focus at one time.
If the magnification increases, DOF and FOV decrease
What is osmosis?
Net diffusion of WATER across a semi-permeable membrane down concentration gradient.
What is diffusion?
Net movement of molecules down concentration gradient.
What was the positive control in the glucose experiment?
The glucose in the dialysis bag.
What was the negative control for the diffusion experiment?
The water
For the amylase experiment, how would you test for denaturation?
Bring the enzyme back to optimal conditions and test for function. for Amylase this is pH of 7 and temperature of 37 degrees celsius.
What gas is released during photosynthesis? What gas is fixed during photosynthesis?
O2 released
CO2 fixed
