1 Chambers A and B are separated by a membrane. Chamber A contains 7.22 M KNO3 and chamber B contains 3.89 M KNO3. If K+ is in equilibrium across the membrane, what is the electrical (potential) difference (Resting membrane potential)? Which side is electrically positive?I am really confused, I calculated it with the Nernst Equation, but I am sure it is wrong...Ek=61/1*log10 (3.89/7.22)=-16.38mVThe side of Chambers B is electrically positive?
2. Using the data provided below calculate the resting membrane potential of this set of cells. Is the inside negative or positive relative to the outside?
Cl- )Intracellular concentration :4 Extracellular concentration:25 conductance:0.15
Na+ )Intracellular concentration :100 Extracellular concentration:7 conductance:0.21
K+ )Intracellular concentration :110 Extracellular concentration:110 conductance:0.10
I used GHK equation and got -26.66mV (I don't know if it is right)
Also how do I know if the inside is negative or positive relative to the outside?
Phosphorous is needed to synthesize the deoxyribonucleoside thriphosphates used in DNA replication. A geneticist grows some E. coli in a medium containing nonradioactive phosphorous for many generations.
If the ATP synthase molecules were randomly orientated so that about half faced the outside of the vesicle and half faced the inside, would you expect ATP to be synthesized.
How could you demonstrate experimentally that the selective antagonist binds the receptor specifically? Illustrate the experiment you would perform and also the controls you would contain.
Modern theory suggests that the early pre-life atmosphere on Earth was a reducing one. Why is it believed that oxygen was not present as life formed on Earth.
He says that the mere presence of DNA is not sufficient to prove the point: his cells may have adopted DNA as a useful molecule quite independently of all other known life forms. What would you do to convince him that he was wrong.
If the centrioles are mispositioned in the cell, the functional mitotic spindle would fail to form. In this state, how will chromosome segregation be affected . Microtubules will not attach to kinetochores.

Compare changes in carbon cycle to that of the nitrogen cycle on human health. Create a conceptual graphical model for how changing the carbon cycle is likely to impact human health.
In many countries, conservationists are trying to design national park systems so that "islands" of natural area (the big parks) are connected by thin "corridors" of undisturbed habitat. The idea is that this arrangement will allow animals and plants..
These experiments demonstrated that DNA is the genetic material of phage and that protein does not transmit genetic information. Can this same experiment be carried out with 35S and 14C? Describe it.
