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.

2. If the plankton in the example above makes 15,000 calories
salantis [7]

Energy available to krill is 1500 calories

<u>Explanation:</u>

Energy produced by phytoplankton = 15,000 calories

Energy available to krill = ?

Along the food chain, only 10% of energy is transferred to the organism of higher trophic level.

Thus,

energy available to krill = \frac{10}{100} X 15,000

                                       = 1500 calories

Energy available to small fish = \frac{10}{100} X 15,00

                                                 = 150 calories

Energy available to medium fish = \frac{10}{100} X 150

                                                      = 15 calories

Energy available to large fish = \frac{10}{100} X 15

                                                 = 1.5 calories

cupoosta [38]
1. Do a pun-net square.
R r
r
r
2. The offspring would be Rr, rr, Rr, rr
3. 2 of them are heterozygous(Rr),which means they would be most likely rough coats
4. Two of them are homozygous for short hair (rr) which means they are going to be soft hair.
5. Your answer is
Rr, rr
