If the paramecium was not able to contract its contractile vacuole, it would be in danger of bursting. The cell would not be able to hold too much water. This would happen faster if the paramecium was in water with a low salt concentration because there is more water and less salt, so the water would accumulate faster.
<span>Bryophytes</span> are more adapted for moist environments. This is due to the fact that they can live in water-filled places with mild temperatures.
They are made from igneous, metamorphic and sedimentary rock.
The echinoderm with long spines
belongs to the class Echinoidea which includes sea urchins, heart urchins, cake
urchins and sand dollars. This spine serves as their protective mechanism from
predators. The spines are joined to the skeleton and muscles surround it. The muscles
enable them to swivel its spines from predators.
The reaction will occur naturally. Positive voltage means it is a working cell.
