The red-green color blindness is a recessive X-linked trait. The females are not affected unless both the X chromosomes have the affected allele. Mostly, the females are the carriers, and the males are affected as they have only one X chromosome. In the given pedigree, the father of Irene have the normal allele, while her mother is a carrier. However, Irene is neither a carrier nor affected. This means that she carries normal alleles on both X chromosomes. Hence, her allele combination is .
Imagine a cell with a semi-permeable membrane that is selective to K+ ions only. The internal solution contains 100 mM KCl and t
1 answer:
Answer:
C. Nernst equation
Explanation:
The Nernst Equation is used to find the equilibrium potential of an ion.
It tells you only what the equilibrium potential for an individual ion is, not what the summed effect of all ions is on the membrane potential.
The formula for Nernst Equation is:
=
In
where F is Faraday Constant, R = gas constant, 8.314 J/mol K
, T = temperature, in K, Z stoichiometric number of electrons in the reaction, is the Reduction Potential in V.
Kindly note that, if we have a squid giant axon at rest with normal intracellular and extracellular ion concentrations. If the membrane permeability to K+ ions is increased, the K+ equilibrium potential (Nernst potential) will stay the same.
