The Vertebrata subphylum has approximately 40,000 living species and is the largest subphylum of the Chordata. The approach we will take will preferably be related to the adaptations that exist in them that favor their survival in the various environments in which they are found.

At first glance, photosynthesis has little or no association with electronics, yet there is potentially a strong connection between these two fields of knowledge. Today, we seek to develop information transmission technologies that are as fast and compact as possible, reaching the molecular dimension (nanotechnology).

Liquid water occupies oceans, lakes, rivers, dams, etc. Continuously and slowly, at room temperature, evaporation occurs, that is, water changes from liquid to gaseous state. The larger the surface area of ​​water exposure (eg an ocean or tree leaves in a forest), the higher the evaporation level.
