Name at least three ways that the Indus River was used by the people of the Indus River Valley to help create their civilization (Lesson 4.11-4.12 & History Book Pgs. 129-134).

Look at my explanation (I have notes on this)

Explanation:

•They divided people off based on their purity

•Government: they were ruled by kings

•Their writing contained 400 symbols, both pictographs and phonetic characters

•Their cities had high walls and laid out in grid system (Citadel was a watch tower and one of the major buildings)

•They had polytheistic religion called Hinduism

the correct answer is c   with the systems

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.
