Select the correct answer from each drop-down menu. Civil engineers conducted a land survey in a hilly region, where roads were carved out between steep hillside slopes. Complete the passage to reveal the engineers’ safety recommendations for the area.

The engineers noted that the area was prone to rockfalls and landslides. They proposed a plan to secure the rocky hillside slopes using (1.wire mesh and bolts, 2. gravel and water, 3. adhesive tape and plastic.)
. They also advised their team that if the slopes are not stabilized, (1. air pressure, 2. magnetismt, 3. gravity)
could cause damaging mass movement without warning.

the answer to your question is sperm

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.
