How does the density of solid water (ice) affect aquatic life? It allows ice to float to the top of water, insulating water below allowing life to live.
It allows ice to sink to the bottom of water, allowing life to live above.
It traps air within solid ice, allowing life to breathe within air pockets.
It produces bubbles as it freezes, allowing life to breathe under water.

answer; i believe the correct answer is ( proteins );

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
