What are structural adaptations for the silky shark

A shark has fins and a streamlined body that help it swim through water. It has gills, which take in oxygen directly out of the water.

Explanation:

Because of its gills, sharks can stay underwater and not have to come to the surface to breathe. Sharks also have a tremendous number of sharp teeth, which make them fierce predators.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
