How things can live
The environment effects organisms in multiple ways. For instance, weather or even the land or water. In mr.G's class, we did an experiment with 5 viles. Each group got either liquid 1,2 or 3. In 2 viles, there were 1cotton ball damp with the liquid we were assigned to, which was liquid 1-salt water. In each vile, we put different substances in them. 1, was brine shrimp, but of course, something happened and the eggs didn't hatch. Brine shrimp should hatch in salt water. Everything else, such as the red sand, radish seeds, orbes, and yeast didn't show any sighns of living. Of course, only because they cant do anything in salt water.
Our living organisms (the brine shrimp) didn't appear living because 1, our brine shrimp didnt work, and the others-if they were living(which they wern't), couldn't grow or live in the salt water. one of the sighns that we took that they wern't living was that nothing moved, no air bubbles or hatching. Only the yeast and orbes expanded, and we figured that it was just from being in the substance (liquid 1- salt water)
