Final Review 25 Jeopardy Template

Microscopy	Hypothesis	Diffusion	Osmosis	Enzyme and substrate
100 objective lenses and eye pieces What is the two parts of the microscope responsible for magnification?	100 testable and falsifiable What are two criteria for a good hypothesis?	100 The solute moves from high concentration to low concentration. What is the movement of the solute during diffusion?	100 deferentially permeable What is the name for a membrane that free allows passage of some solutes but excludes passage of others?	100 point at beginning of linear phase, point at end of linear phase What two points should be used to calculate initial velocity on the graph drawn on the board?
200 condenser or diaphragm What part of the microscope enhances contrast by concentrating light?	200 bird size and wingspan "As the climate warms, birds are shrinking and their wingspans are growing." What is(are) the dependent variable(s)?	200 Collisions between molecules resulting from thermal motion causes the molecules to disperse (diffuse). The frequency of these collisions determines rate of diffusion. What is the relationship between thermal motion of molecules and rate of diffusion?	200 isotonic What environment do animal cells prefer?	200 Product is present prior to first measurement so contamination of substrate with enzyme or delay taking measurements from spectrophotomer. What is a reasonable cause of the graph on the board?
300 toluidine blue What stain differentiates cellular compartments by pH?	300 climate change "As the climate warms, birds are shrinking and their wingspans are growing." What is(are) the independent variable(s)?	300 kinetic theory of molecular motion Why do molecules diffuse faster at higher temperatures?	300 The osmotic pressure from water flowing in causes the cell to rupture. If the cell had a cell wall such as Elodae the cell wall would provide support and prevent lysis. Why do red blood cells lyse (burst) in hypotonic environment? (Be sure to mention water flow, osmotic pressure, and cell wall)	300 No product is produce so the either the enzyme is not active due to denaturation or suboptimal pH. What is a reasonable cause of the graph on the board?
400 acetocarmine What stain binds chromatin?	400 birds prior to climate change "As the climate warms, birds are shrinking and their wingspans are growing." What would be a plausible control group?	400 number of collisions to generate force to move molecule through pores in the matrix Why do molecules with smaller molecular masses diffuse faster?	400 7.5M What is the final concentration of the solution outside the bag in the following? 5M sucrose inside the dialysis bag, 10M sucrose outside the bag.	400 The plot with the highest initial velocity What is the preferred pH of the enzyme studied in the plots on the board? (All plots are the same enzyme)
500 numerical aperture What determines the ability of a microscope to resolve a specimen at fine detail?	500 evaluate individually What is a good hypothesis to test the effects of stress related to finals on undergraduate students?	500 Higher concentrations increases the frequency of collisions between the molecules propelling them through the gel matrix faster. Why do solutes with higher concentrations diffuse faster?	500 Ions: 4+(2)2=8 8*5 = 40 What is the osmolarity of 5M NaH2PO4(H2O)2?	500 The plot with the highest initial velocity What is the preferred temperature of the enzyme studied in the plots on the board? (all plots are the same enzyme.)
