Question

This map shows the extent of hypoxia in Long Island Sound from 1991 through 2009. (The units are in milligrams per liter, ormg/L.) What can you conclude from this map?A. Most years, all of Long Island Sound is well oxygenated to support marine life.B. Hypoxia is a problem that has only been occurring in Long Island Sound since 2009.C. Most years, the water near New York has inadequate oxygen to support marine life.D. All of Long Island Sound has always been a hypoxic area.

Answer 1

Hypoxia is the state which oxygen is not available in sufficient quantities at a tissue level in the body to maintain the homeostasis. The graph shows the concentration of this condition in Long Island Spund from 91 through 09 in mg/L, showinng in the data that the west area of the region has more cases os hypoxia than the east. Therefore, between the options the one that is a true statement about how well oxygenated to support marine life the region was during that period is the letter C. most years, the water near New York has inadequate oxygen to support marne life.
