The following dot plot represents a random sample of elementary students and the number of children that live in their home.

If this random sample is representative of elementary students in the United States, which of the following inferences can be made from the data? Select all that apply.

The majority of the households in the United States, with at least one child, contain less than three children.
Very few households in the United States contain four or more children.
All households in the United States contain at least one child.
None of the households in the United States contain five children.

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.
