Answer:

The envelope is an outer lipid bilayer that is studded with proteins. The function of the envelope is to identify and bind some receptor sites on the host membranes. After fusing with the cell membrane, it allows to capsid and genetic material to enter the cell and infect it.

Rna processing drag the correct labels under the diagrams to identify the events of rna processing.

Elena-2011 [213]

In the beginning of the RNA strand as a cap, a modified guanine nucleotide is added. After this, there is a removal of those segments of the RNA strand that do not actually code for the protein. And those RNA’s segments that do code for the protein are reconnected. And forking a tail, extra adenine nucleotides are added to the end of the RNA strand. The mRNA or messenger RNA which is already completed will then leave the nucleus. This whole process is called the RNA processing. Before the RNA copy of a protein encoding can be transported out of the nucleus and translated into protein, it must be first be modified in several ways. A precursor of mRNA, pre-mRNA is the primary transcription product of a gene.

While distinctly Anthropoids, some Platyrrhines maintain a few of traits that are typically represented only in Prosimians. For

crimeas [40]

Convergent evolution is the concept of two or more species evolving similar traits despite being completely unrelated to one another, including the absence of a common ancestor.

The Platyrrhines, more commonly known as "New World Monkeys", share many characteristics with the Prosimians. Some of these include:

Teeth layout
Diet
Eyesight
Sleeping habits

and more.

The Platyrrhines and the Prosimians are both nocturnal animals. Despite all other members of their family being active during the day, the Playrrhines have evolved nocturnal habits similar to that of the Prosimians. Aside from that, they feed on insects more so than fruit, which is reflected by the layout of their teeth, and have eyesight well adapted to dark conditions. All of these are traits they share with the Prosimians.

Despite being in different ecosystems and regions, and sharing no recent common ancestors, both of these species have evolved strikingly similar traits. This can be used to corroborate the theory of convergent evolution, which explains how two species can evolve very similar traits despite being unrelated.

Answer:

The phenomenon is called convergent evolution

Explanation:

Convergent evolution is the name given to the evolutionary phenomenon whereby a similar characteristic appears independently in two unrelated species, that is, that do not have a direct common ancestor from whom they could inherit that characteristic. Similar characteristics resulting from evolutionary convergence are called analogues or homoplasms (from the Greek, “shaped in the same way”). This process is very common and can be explained by natural selection, since similar selective pressures tend to favor similar adaptations.
