I'm pretty sure the answer is B
Answer: Contractile vacuole of amoeba will shrink/contract when the organism is placed in sea water.
Contractile vacuole is a subcellular structure ( mainly found in protists) that is involved in the regulation of water quantity inside a cell.
As we know that water always flow from a hypotonic ( where solute concentration is less) to a hypertonic ( where solute concentration is more) solution. Sea water is a hypertonic solution as the concentration of salt is very high. Therefore, in this case, water will flow from contractile vacuole to outside of the organism.
Thus, contractile vacuole of amoeba will contract as it will lose water when placed in sea water.

Answer:
The fluid mosaic model was used to explain the structure of the cell membrane. This model was well accepted model and given by Singer and Nicolson.
According to this model, the cell membrane is composed of lipids and proteins. The lipid layer is arranged and the proteins are inserted or span the bilayer. Some proteins are trans-membrane proteins, peripheral proteins and integral membrane proteins. Cholesterol are also inserted in this membrane. The carbohydrates are present in association with proteins or lipids on the cell membrane.
