Which sources do scientists use to study the interior of earth? check all that apply. earth’s orbit - core samples - sea level - earthquakes - s waves - rock composition

Core samples, earthquakes, S waves and rock composition are the sources do scientists use to study the interior of Earth.

The samples of core layer of the earth tells us about interior parts of the earth because the core is present inside the earth so the samples of core provides information about the interior of earth. The composition of rock that comes from the interior of earth due to volcanic eruption that also provides information about earth.

Scientists are able to understand Earth's interior by studying seismic waves because these waves travels through the earth interior materials so we can say that Core samples, earthquakes, S waves and rock compositions helps scientists to study the interior part of Earth.

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
