When the developing embryo has divided into 32 cells, it is called a:

RNA
Induction
Nucleolus
Morula

The correct answer is: Morula

At this stage, the embryo is still a ball of cells and has not yet formed differentiated tissues or organs. This process is called cleavage and the resulting cluster of cells is called a morula. RNA and nucleolus are cellular components that are important for protein synthesis and gene expression, but are not relevant to the development of an embryo. Induction refers to the process by which cells influence the development of neighboring cells, but it is not specific to the 32-cell stage of embryo development. Therefore, D is the best answer.
