Afederally funded project was halted when an endangered species was found on the land. this probably occurred because
a. the u. s endangered species act forbids the development
b. a reintroduction program was under way
c. the endangered species was an animal and not a plant
d. the endangered species list needed to be updated

The correct answer is option A.

Explanation:

One of the most effective and important environmental laws of the United States is the Endangered Species Act. It signifies a commitment by the citizens of the nation to restore and protect the species that are at threat of getting disappeared forever. The Act was passed in 1973 by the government established at that time.  

The act provides balanced solutions for the landowners, government agencies, and concerned individuals to safeguard wildlife and the habitat in which they live. Thus, the act is encouraged to prevent extinction, recover jeopardized animals and plants, and safeguard the ecosystems on which they rely upon.  

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.
