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.
Phylogenetic trees show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms.
Answer:
5' --> 3'
Explanation:
New nucleotides are added to the hydroxide group on the ribose sugar side. That is the 3' side.
I do believe that it is both naturally occurring and caused by human activity. Although science has proven that it is something that naturally progresses with time, humans have sped up the process. Hope this helps:)
The correct option is this: THE TROUTS GROW FASTER BUT HAVE SHORTER LIFE SPAN.
Trouts live in fresh waters such as streams and lakes, they feed on microscopic organisms, small fish and insects. They have a maximum length of about 35 inches and they are excellence sources of omega 3 fatty acids. Trouts have relatively short life span.
