False. Their exoskeletons are made of silica.
the specific gravity of
pure sulfuric acid is---------> approximately 1.835 g / cm3
the specific gravity of
water is -------------------- >1.000 g / cm3.
The electrolyte, that
is, the dissolution of sulfuric acid in water, is usually at a rate of 36%
acid, so that, in a fully charged element, we can deduce the electrolyte
density, is 1.295 g / cm3. (see attached table)
The specific gravity is
actually the difference in the weight of water compared to a specific fluid. It
is measured with a hydrometer
The plants remaining would be the only plants then will come as the animals die because they cant eat plants because all the plants are gone then will come us which we will die because there aren't any animals to thrive on
