Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function.
The four mechanisms are as follows:
1) Orographic lifting: Air is forced to rise over a mountainous barrier
<span>
2) Frontal wedging: Warmer, less dense air is forced over cooler, denser air along a front
</span>
<span>3) Convergence: Pileup of horizontal air flow resulting in an upward flow
</span>
<span>4) Localized convective lifting: Unequal surface heating causes localized pockets of air to rise because of their buoyancy. </span><span />

Answer:
C) cell differentiation.
Explanation:
Cell differentiation is a process undergone by a cell in which it changes to a specialized form. During the process of cell differentiation, some genes in a single cell becomes turned off or on in a process called GENE EXPRESSION to give rise to cells with specialized functions.
This is the case of this sponge whose specialized cells perform unique functions like ingesting food, support, and reproduction. The specialization of the cells within the sponge is as a result of the process of CELL DIFFERENTIATION.
