Answer: One of the foods was sour and one was sweet
Explanation:
The sweet one has changed because it has more sugar then the sour one, It either got moldy or melted.
Answer:
b. the rate of destruction is equal to the rate of carbonate input.
Explanation:
At the Calcite Compensation Depth(CCD) the rate of addition of calcite and dissolution of the mineral is the same. Below this depth, all calcite minerals are dissolved.
The CCD occurs at a depth of 3000-4000m. It varies from places to places within the ocean. Other factors play important roles in determining the CCD. Some of the factors are temperature and pressure.

To be floating, the gravity force of the iceberg should be same as the buoyancy force that result from the difference of the ice and water density.
The density of ice is 920 and water is 1030, then the difference should be: 1030kg/m3-920kg/m3= 110kg/m3
Let say that the volume of ice below the water is volume1 and the volume above the water(exposed volume) is volume2.
You can get this equation
volume1+volume2= 100%
volume1= 100%- volume2
Insert it into the buoyancy and gravity force will result
buoyancy=gravity
110kg/m3*volume1= 920kg/m3 *volume2
110kg/m3*(100%- volume2)= 920kg/m3 *volume2
110kg/m3 - 110kg/m3*volume2= 920kg/m3 *volume2
110kg/m3 = 1030kg/m3 *volume2
volume2= 110/1030= 0.1067= 10.7%
