Answer:

It ocurred a selection by allopatric speciation

Explanation:

The allopatric speciation refers to the evolution in which the same specie starts developing different characteristics because of geographic barrers and this characteristics after some time generates two different specie.

It happens because usually according to the environment or the predators, species have to develop different adaptations so they can survive. In this case we have two different types of camouflage adaptations made by the salamanders acording to the conditions so for one specie it is better to camouflage from the predator mean while to the other is better to use lived colors to seem as it is a poisonous animal and in this way avoid the predators.

So you can see the same specie develop different strategies to survive because of a geographic separation, generating an allopatric speciation.

Alex17521 [72]

Answer:Phosphorylation cascades are similar to a row of dominoes falling down, instead of one domino knocking down the next, a phosphate being added activates the message. In this way, a series of different _(phosphate group) are each _(added ) after another. Inactive protein kinase 1 gets a __(phosphate group_)___ added and now it is active protein kinase 1. Active protein kinase 1 transfers a (phosphate group) and now inactive protein kinase 2 is now ___(active)_____. This continues until the desired (protein ) is activated to cause a cellular response.

During the early days of deciphering the human genome, scientists were surprised to find that the number of genes appeared to be
Alekssandra [29.7K]

Given what we know, we can confirm that the aspect of nucleic acids and transcription that can help explain this discrepancy is that of alternative splicing.

<h3>Alternative Splicing.</h3>
  • This process allowed the cells to use a single gene for the creation of various proteins.
  • This process includes the separation of RNA at splicing sites to create new versions of the mRNA strand.
  • This helps to increase the diversity of mRNA's available and create more proteins.

Therefore, given that alternative splicing allows the cells to create multiple forms of distinct proteins from a single gene, this allowed our organisms to develop the vast number of proteins we use, without the need for a much larger genome.
