Global and local climate change also makes marine ecosystems more vulnerable to lower oxygen levels (hypoxia). Aquatic organisms cannot survive without the presence of dissolved oxygen in the water.
When the climate is warmer, the surface water warms up more quickly and its density becomes lower than that of the underlying waters. However, it is the mixture of waters of different depths that helps to oxygenate the deeper waters. If the surface water is warmer and less dense, it mixes less well with the more dense bottom waters. As a result, the oxygen content will be lower in some places (deeper places for example).
At oxygen levels below 30%, species that do not tolerate hypoxic conditions must migrate to other geographic areas. If they can not migrate, their survival may be threatened.
Out of the following given choices;
A. The cell is unable to get more water into the cell.
B. The cell is unable to build more protein molecules.
C. The cell is unable to produce water molecules inside the cell.
D. The cell is unable to maintain a stable internal environment.
<span>The answer is D. Due to high amounts of proteins in the cell, osmotically
active proteins cause the internal environment of the cell to be hypertonic to
the extracellular fluid. This causes excess water to enter the cell by osmosis and
resulting in lysis. </span>
