Answer:

Pax6 is an evolutionarily conserved transcription factor that activates genes involved in eye development in several animal groups ranging from vertebrates to invertebrates

Explanation:

The Paired box 6 (Pax6) gene is a conserved transcriptional factor involved in regulating eye development across bilaterian species. This homeotic master gene may also play different functional roles in different animal groups. For example, in vertebrates, Pax6 is also required for the formation of the central nervous system (CNS) and pancreas. In invertebrates, Pax6 homologs are responsible for the development of nonocular head structures. In <em>Drosophila</em>, there are two homologs of the Pax6 gene, eyeless (ey) and twin of eyeless (toy), which are involved in eye specification and cell proliferation, respectively.

Phoenix [80]
The nurse should administer an injection of postexposure prophylaxis for tetanus. Tetanus is a toxic substance produced by a bacterium that cannot survive air (oxygen) exposure, that is why deep wounds are more vulnerable to tetanus. A moderate burn injury is considered an open dirty wound, therefore the patient should be protected from tetanus.
There is a vaccine for tetanus, that provides immunization from this disease, but it needs to be repeated every 10 years. However, in cases where there is an open dirty wound, the vaccine is believed to be inactive if it was not done within the last 5 years.
In this case, the child will not receive the tetanus vaccine, but an injection of active immunization, which acts much faster, but does not last as long as the vaccine.
