Mesohyl contains:

a. a polysaccharide gel and dead cells.

b. a collagen-like gel and suspended cells for various functions.

c. spicules composed of silica or calcium carbonate.

d. multiple pores.

A. with respect to controlling atmospheric carbon dioxide, the "solubility pump" is most important:
-in the deep ocean
-in the surface ocean
-at hydrothermal vents
-at the oxygen minimum
B. nonconservative constituents of seawater are:
- often tied to biological cycles or are chemically reactive
-distributed evenly everywhere in the ocean
-tend to have long residence times in the ocean
-have very low Flux rates associated with inputs and outputs
-very abundant in seawater
C. increases in acidity in the ocean can result in
- precipitation of calcium carbonate
-the dissolution of carbonate minerals or carbonate skeletons of organisms
-production of oxygen through carbonation
-increases in pH
-an increase in salinity
