If you were conducting the wire/compass experiment (Part A) near the equator instead of in Oregon, would it be necessary to use more or less wire current to cause the compass needle to deflect? (This is related to the dip angle) Explain why.

Imagine that you have placed a compass due east of of a wire where current equals 2A (the wire is vertical and current travels from bottom to top). 1. If you turn the current on, how would the compass respond? (Does it change cardinal direction?) 2. How does the magnitude and direction of the total magnetic field change? PLEASE EXPLAIN!

a. You are conducting a lab experiment on the promoter regions of genes. In one experiment you apply heat to two sections of DNA that you believe could be promoter regions. One region unwinds at 80 degrees C and the other unwinds at 60 degrees C. Which of the two strands contain the promoter? Explain. b. Apply your knowledge of genetics to explain what would happen in a nucleus if histones were negatively charged.

a chem 1515 student does the same experiment as the one you will be conducting this week but at a different temperature. She mixes 5.00 mL of 1.00 x 10-3 M solution of Fe(NO3)3 with 5.00 mL of 1.00 x 10-3 M KSCN solution. She finds out the equilibrium concentration of FeSCN2+ at theis condition to be 2.5 x 10-5 M. What is the value of the equilibrium constant for the reaction? Fe3+ (aq) + SCN- (aq) <--> FeSCN2+ (aq)

2. Imagine that you are conducting an experiment that compares the effects of drought on photosynthesis in two species in the family Ericaceae: Vaccinium parvifolium (red huckleberry) and Vaccinium oxycoccos (small cranberry), both native to Oregon. What methods (name 2) could you use to measure water stress or availability in this experiment? Why might you need to know if these plants have either C3 or C4 photosynthesis? Explain. Design a greenhouse experiment that would allow you to address competition between...
