Two solutions are separated by a semipermeable membrane that is permeable to sodium but not chloride or potassium ions. Solution A on the left contains a solution that is 100 mM NaCl, while Solution B on the right has a concentration of sodium chloride of 1 mM.
There is an electrode in both solutions, and a comparative assessment of voltages between the two compartments is being made. The investigator doing the study decides to call side A ground potential (or, in other words, defines it as 0).
What is the value for the sodium equilibrium potential in this condition? (show how you calculate this)
In one sentence, describe why it has a positive or negative value.
What would be the value of the chloride equilibrium potential? (show how you calculate this)
What is the voltage of side B relative to side A?
Does the chloride equilibrium potential contribute significantly to the voltage actually being measured by the investigator? Why or why not (one sentence)?
Determine the events that mark the starting and the end of the first interphase period? What happens within the cell in this period?
How does these organelles differ with regard to this process.

In what brain structure would you expect cocaine to have the largest effect on dopamine transmission and why.
In mountain rabbits, the EL-1 gene is located on chromosome three. 7-alleles of this gene have been identified in the population. With respect to EL-1,
Describe why asexually reproducing organisms are generally found in environments that do not change very much through time, while sexually reproducing organisms are very successful in environments.
What are the disadvantages and advantages of synthetic vs natural proteins? I have been googling for hours and not really finding anything so any help would be great.
Cells have several mechanisms to prevent the production and accumulation of truncated protein fragments. To illustrate why these fragments can be deleterious.
Compare and contrast the benefits and consequences of salt and sugar as a preservative. How could a food manufacture that produce food intended for a low salt diet ensure a long shelf life?
Many people will buy freshly picked corn from a farmer's market and immediately take it home, husk it, boil it for several minutes in water, and then cool it quickly in cold water. They will then cut the corn off the cob and freeze it for later us..
Discuss what you would require to know to answer the following question: of all proteins that exist on earth at this time, what fraction of them have a known structure?
Autoimmune haemolytic anaemia is caused in general by auto anti bodies of the IgG and IgM classes. Can antibodies of other classes such as IgA, IgD, IgE cause autoimmune haemolytic anaemia.
