Answer:
g = 1.11x10⁻⁵Ω.
Explanation:
The membrane conductance (g) can be calculated by dividing membrane current (I) through the driving force (Vm - E) as follows:
![g_{ion} = \frac{I_{ion}}{V_{m} - E_{ion}}](https://tex.z-dn.net/?f=%20g_%7Bion%7D%20%3D%20%5Cfrac%7BI_%7Bion%7D%7D%7BV_%7Bm%7D%20-%20E_%7Bion%7D%7D%20)
<em>where Vm: is the membrane potential and </em>
<em>: is the equilibrium potential for the ion or reversal potential. </em>
The equilibrium potential for the ion can be calculated using the Nernst equation:
<em>where R: is the gas constant = 8.314 J/K*mol, F: is the Faraday constant = 96500 C/mol, T: is the temperature (K), z: is the ion's charge, [ion]out and [ion]ins: is the concentration of the ion outside and inside, respectively. </em>
Now, we can calculate the membrane conductance (g) using equation (1):
![g_{ion} = \frac{I_{ion}}{V_{m} - E_{ion}} = \frac{-318*10^{-9} A}{20*10^{-3} V - 48.78*10^{-3} V} = 1.11*10^{-5} \Omega](https://tex.z-dn.net/?f=%20g_%7Bion%7D%20%3D%20%5Cfrac%7BI_%7Bion%7D%7D%7BV_%7Bm%7D%20-%20E_%7Bion%7D%7D%20%3D%20%5Cfrac%7B-318%2A10%5E%7B-9%7D%20A%7D%7B20%2A10%5E%7B-3%7D%20V%20-%2048.78%2A10%5E%7B-3%7D%20V%7D%20%3D%201.11%2A10%5E%7B-5%7D%20%5COmega%20)
Therefore, the membrane conductance is 1.11x10⁻⁵Ω.
I hope it helps you!
Answer:
D. thymine, adenine, and cytosine (TAC)
Explanation:
DNA gets synthesised into an mRNA which gets synthesised into a peptide chain and eventually forms a protein.
In order to know where to begin joining up a peptide chain from amino acids, the protein-synthesis machinery searches for a start codon.
This is the three bases AUG, which code for the amino acid methionine.
Since the start codon in an mRNA is AUG, that means in the <u>DNA</u>, the initiation code will be <u>complementary</u>, so it will be TAC.
Corrosion of aluminium metal is a chemical process. Corrosion happens when a certain chemical reaction takes place.
Answer:
The moment magnitude scale is a scale that rates earthquakes by estimating the total energy released by an earthquake . Estimating the total amount of energy released, enables comparison of earthquakes more accurately.
