What is osmosis and discuss tonicity? Then use contextual evidence to identify evidence that correlates with the title of the article. Begin Reading Section 7.2

  1. New research shows that the oldest complex lifeforms on Earth likely fed by osmosis. The organisms lived in the oceans more than 540 million years ago and absorbed nutrients through their outer membrane. The study provides new insight into the evolution of life on Earth. OSMOSIS is the Diffusion of water through a selectively permeable membrane. the Osmosis fed these lifeforms millions of years ago. i can't find tonicity.

  2. Bishop Ashburn:
    The students at virgina tech found the oldest liveing organisms that live under the oceans more than 540 million years ago and absorbed nutrients from there outer membrane to live so long the students found that new insights into evolution of life on earth. osmosis is a diffusion of water through a selectivly membrane. the nutrantes fed the organisms to keep them alive

  3. research said that older complex lifeforms were likely fed by osmosis.they lived in the ocean for more than 540 million years ago suposely and got nutrients through the outer mrmbrane.the deffenition of osmosis is the diffusion of water through a selectively permeable membrane.the deffenition of tonocity is the osonomic pressure or tension of a solution as in if cells would swell or shrink due to the tonocity of the envirment. wyatt matthews

  4. earth likely feed by osmosis.the onas article concludes that today giant sulifur bacteria.osmosis is a term used to describe the moment. only microscopic bactira find it efficent to us only osmosis to feed.

  5. osmosis is the diffusion of water through a selectively perameable membrane.Osmosis is a term used to describe the movement of a solvent, such as water, across a semi-permeable membrane. Such membranes have small holes that allow some materials to flow from one side to the other. New research shows that Ediacaran organisms may have used osmosis to absorb nutrients. by kenyatta rogers

  6. based on research they conclued that the older complex lifeforms was fed by osmosis. the food they fed it with lived in the ocean 540 million year ago
