A) Signaling Factors cause precursor neurons to produce neurons.
B) Stem cells arise from the inner mass of cells.
C)Genes that lead to the production of undifferentiated precursor neurons are activated.
D) Signaling factors trigger differentiation in stem cells.

Answer 1

1. Stem cells arise from the inner mass of cells.
   
2. Genes that lead to the production of undifferentiated precursor neurons are activated.
   
3. Signaling factors trigger differentiation in stem cells.
   
4. Signaling Factors cause precursor neurons to produce neurons.
   

Step-by-step explanation:

The steps in the development of neurons must occur in a specific order for the process to be successful. In the first step, stem cells arise from the inner mass of cells. These stem cells are unspecialized cells that have the potential to develop into a wide range of different cell types.

Next, genes that lead to the production of undifferentiated precursor neurons are activated. These genes provide the instructions for the stem cells to begin developing into neurons.

Once the precursor neurons have been produced, signaling factors trigger their differentiation. This means that the precursor neurons become specialized and begin to develop into specific types of neurons.

Finally, signaling factors cause the precursor neurons to produce neurons, completing the development process. This is a critical step because it ensures that the neurons are able to function properly and play their role in the nervous system.
