The scientific notation for that is
3.134 * 10^9
This is because you move 9 places then put it to a exponent.
The squirrel is the primary consumer because it directly consumes the acorns from the oak tree.
That then right after heat it evaporates and then the water that is still in the bowl lowers because of the heat that sends out water molecules that just disappear. :)
Siltstone and sandstone are both granular materials but they are distinguished by grain size. The Wentworth scale places silt particles between 0.0039 to 0.0625 mm. This is smaller than very fine grained sand.
Siltstone and Sandstone may have identical mineralogy. They are generally comprised of quartz, feldspar and rock fragments. Because siltstone is comprised of smaller grains, it has smaller pore throats, resulting in lower permeability and higher capillary pressures than in an equivalent porosity sandstone.
If it were single celled, then it would need some form of protection so the answer would be C. an outer covering
