Oysters ive in water and have shells. pollution in the ocean waters where the oysters live has increased the amount of salt in the water. what is the most likely way that an oyster will adapt to the changing salt levels in the water?

The correct answer world is -it will tightly close the Shell until the water salinity gets normal.

Explanation:

Oysters are the marine organisms that have a shell on their body which helps this organism to adapt to the environment changes. This shell also protects oysters from predators.

These organisms also are known for their filter property as they filter almost 50 gallons of water on a daily basis by closing their shell tightly that prevents salt to pass through them and the only freshwater comes out.

Thus, the correct answer is - it will tightly close the Shell until the water salinity gets normal.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
