Answer:

- Evidencia: registro fósil

- Función: capacidad de distinguir depredadores  

Explanation:

Un ojo compuesto es una órgano sensorial altamente especializado compuesto por unas estructuras conocidas como omatidios, las cuales están a su vez compuestas por células fotorreceptoras. La superficie externa de un omatidio es una lente hexagonal, debajo de la cual se encuentra una lente cónica capaz de captar la onda lumínica. La evidencia más importante de animales con ojos complejos que habitaron el planeta hace millones de años fue el descubrimiento de un ojo fosilizado en un crustáceo (aprox. 515 millones de años atrás). El ojo de este animal estaba compuesto por miles de lentes. Interesantemente, las lentes del centro del ojo compuesto se destacaban por su mayor sensibilidad, lo cual se cree le conferían a este crustáceo la habilidad de distinguir mejor estructuras y formas en ambientes oscuros. En consecuencia, este descubrimiento soporta la idea de la evolución temprana de la vista como una característica fundamental que le habría conferido a una especie de crustáceo la posibilidad de distinguir fácilmente a sus depredadores.

Which structure would be unaffected by the peripheral nervous system?
Delicious77 [7]
<span>Meninges is the structure that would be unaffected by the peripheral nervous system. Since the Peripheral Nervous System or PNS is made up of motor and sensory nerves, then the other optioin would be cancelled out because they are controlled directly or inderictly by the motor neuron. Meninges on the other hand is a tough tissue that is composed of three membranes which cover the brain and the spinal cord.</span>
