The incorporation of valinomycin, a neutral antibiotic, into a polyvinyl chloride membrane allows for the manufacture of an ion-selective electrode that is highly selective for potassium.
<h3>How Valinomycin Ionophores Enter and Transport K+ across Model Lipid Bilayer Membranes?</h3>
- A biomimetic lipid membrane attached to the surface of the gold electrode contained the cyclic peptide valinomycin.
- The ionophore characteristics of the peptide were investigated using electrochemical impedance spectroscopy, and the conformation and orientation of the antibiotic valinomycin within the membrane were identified using polarization modulation infrared reflection absorption spectroscopy.
- By forming a complex with potassium ions and an ion pair with a counter anion, valinomycin transports ions across the membrane, and the combination of these two techniques revealed novel information about the ionophore mechanism.
- The ion pair is located inside the hydrophobic portion of the membrane and makes a little angle of around 22° with the surface normal.

Yes it can turn into sedimentary or metamorphic rock
Epididymis would be the correct answer, can i get brainliest please

I'm amazing my friend how about you?
Answer:
Precipitation and runoff
Explanation:
The oceans get water in several different manners, with some of them being through precipitation, and through runoff. Whenever there is precipitation on the ocean waters, the water from it of course ends up in it, thus it accumulates it. Also, when there's precipitation on the land, a runoff appears. The runoff is simply the water from the precipitation that moves on the surface, downhill, and usually ends up in some water body. Part of the runoff ends up in the oceans, and that is the runoff that appears on the slopes that are near the ocean and are sloping toward the ocean waters.
