Answer:
Phylogenetic trees can be described as diagrams which represents the evolutionary histories of organisms. The organisms that share more common traits or functions are more closer to one another in the diagram.
The phylogenetic tree in the above diagram shows that the ancestors of Danes, Chinese and Tibetans carried the regular EPAS1 alleles.
According to the tree, the Chinese are more closer to the Tibetans as they carry the Tibetan EPAS1 alleles which the Danes do not carry.
Huh what that’s not an question
Answer:
Transition
Explanation:
Secondary succession occurs when the existing vegetation is removed by some disturbances and soil is already present in the region to support the growth of new species. During succession, the early species are being replaced by later successional species.
In the given example, the forest has patches of early species and later species. This means that the forest is in the transition period of succession where early species were not completely replaced by the new species. Once the early species will be removed and the climax community develops, the forest has reached the final stage of succession.
According to the research, the linear vein is a tributary blood vessel of the hepatic portal vein.
<h3>What is the hepatic portal vein?</h3>
It is a blood vessel that carries deoxygenated blood from the digestive organs and the spleen to the liver.
The linear vein is one of the branches of the celiac trunk that supplies the spleen and gives off branches to the stomach and pancreas.
Therefore, we can conclude that according to the research, the linear vein is a tributary blood vessel of the hepatic portal vein.
