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.

In an ecosystem, energy from the Sun is transferred by way of _____.
Lorico [155]

Answer: food chains or webs

In an ecosystem, energy from the sun is transferred by the way of food chains or webs. A food chain is a linear sequence of organisms through which food and energy is passed as one organism eats the another. A food web is the interconnection or relation of food chains. In a food chain energy is distributed among the trophic levels. Plants are primary producers which traps energy from sun for photosynthesis and belong to first trophic level in the food chain. The energy of sun present in plants is transferred to subsequent higher trophic levels when plants are consumed by other organisms.

Copying of the information in dna into rna, which can exit the nucleus is called
Oksi-84 [34.3K]
Definition:
                 "Copying of information from DNA to RNA which exit nucleus is                                                         known as transcription"

Explanation:

                    Transcription is a vital process for living organisms, because it is a staring point for protein synthesis. It occurs inside the nucleus and is carried out by RNA polymerase enzyme. In eukaryotes RNA pol is of three types: these are RNA Pol 1, RNA Pol 2, and RNA Pol 3. In prokaryotes it is of only one type.

Steps in transcription:
                                     Transcription consists of three main steps
1. Initiation:
                   In this step RNA pol attach to DNA template at 5 prime end in the promoter region to start the formation of complementary strand of RNA.  In prokaryotes there is a region called <span>Pribnow box, with the </span>consensus sequence<span> TATAAT present about 10 base pair away from site that serves as a transcription initiation. In eukaryotes the promoter region is more complex it contain activator and enhancer.

2. Strand elongation:
                                   </span><span>Once transcription is initiated, the DNA double helix unwinds and RNA polymerase reads the template strand, adding nucleotides to the 3′ end of the growing chain.
</span>
3. Transcription Termination:
                                                T
erminator sequences are found close to the ends of non-coding sequences. Before termination polyadenylation occurs.  <span>
