of this type of molecules.
10
9)Since the phospholipid bilayer has a fluid
consistency and is studded with protein
molecules, this is the name of the model
representing it.

21
20) Small spherical structure formed by
pinocytosis, containing E.C.F
22
21) Type of solution where crenation may occur.
23
22) Type of solution where plasmolysis may occur.
24

increases.
27
26) Type of solution where dynamic equilibrium
exists
