Electrochemistry Activity 1 Data Table Determining the Cell Potentials Measured Cell Potential (V) Theoretical Cell Potential (V) Percent Error Mg / Fe2+ 0.44 Mg / Cu2+ 0.75 Fe / Cu2+ 1.3 I have the measured data from the lab, but am needing help with the other two parts. Thank you.
A given intensity of injected current will produced a larger potential change in a small cell than in a large cell having similar membrane characteristics. Why?
Explain why relatively small changes in companies’ revenues can result in relatively large changes in their earnings or losses. In other words, if a company’s sales increase 12%, why do its earnings not also increase 12%?
In principle, can the membrane potential of a cell ever be equal to the equilibrium potential for an ion? If yes, under what circumstances; if no, why not? Explain your reasoning.
3. Explain why the cell potential for an operating galvanic cell decreases over time but does not change from a positive value to a negative value. T A
1) Action potential a) Explain how an action potential moves down a cell wall. Be very specific about what generates a force, and what exactly moves. Explain how the membrane chemistry play a role. b) Explain what electrical signals are available for measuring in the case of the heart, brain and nervous system, and muscles. Give details regarding timing and magnitude. c) Explain how the signals described in b) are measured in practice. Give details about techniques or particular circuits...
Staphylococcus aureus can only cause disease when the cells reach a certain population size. Explain how S. aureus senses its cell density and activates gene expression. Based on this knowledge, discuss how antibacterial drugs can be designed to disrupt virulence and why these drugs have potential advantages over antibiotics to treat S. aureus infection.
Can competition or predation cause extinction? Why or why not? Please explain your answer in detail.
If your sample has impurities, would the melting point range be large or small. Explain why.
The standard deviation can be thought of as the average error. Please explain why this is true.
