The worldâs largest and possibly oldest living organism is Pando, a Quaking Aspen clone in Utah.Karen Mock, Professor of Molecular Ecology at Utah State University tells host Steve Curwood that precise estimates about the age of Pando are not currently possible, but it may be many thousands of years old.hat means it started sprouting when modern humans were migrating out of Africa. But the worldâs largest organism is now under threat. Here to explain why are Paul Rogers, Director of the Western Aspen Alliance at Utah State University and Karen Mock, Professor of Conservation Genetics and Molecular Ecology at USU.
Osmosis is best defined as the movement of. molecules from an area of high concentration to an area of lower concentration. molecules from an area of low concentration to an area of higher concentration.water molecules across a membrane from an area of low water to an area of higher concentration.smosis is best defined as the movement of. molecules from an area of high concentration to an area of lower concentration. molecules from an area of low concentration to an area of higher concentration.
A solution with low osmolarity has a greater number of water molecules relative to the number of solute particles; a solution with high osmolarity has fewer water molecules with respect to solute particles.
