1. Answer;
They evolved separately as they moved north and became two separate species.
Explanation;
The greenish warblers weren't geographically isolated, but they migrated around the Tibetan Plateau, evolving separately until they were no longer able to interbreed when both species (East and West) contacted in Siberia.
Greenish warblers were thought to have evolved from a single ancestral population that gradually diverged into two new species as it expanded northwards around the Tibetan plateau.
2. Answer;
- Their plumage patterns.
- Genetics and history
Explanation;
West Siberian greenish warblers (P. t. viridanus) and east Siberian greenish warblers (P. t. plumbeitarsus) differ subtly in their plumage patterns, most notably in their wing bars, which are used in communication. While viridanus has a single wing bar, plumbeitarsus has two. Around the southern side of the ring, plumage patterns change gradually.
Additionally, the two northern forms viridanus and plumbeitarsus are highly distinct genetically, but there is a gradient in genetic characteristics through the southern ring of populations. The greenish warblers were once confined to the southern portion of their range and then expanded northward along two pathways, evolving differences as they moved north. When the two expanding fronts met in central Siberia, they were different enough that they do not interbreed.
The Senate "cools" legislation from the house like a saucer cools coffee. The Senate approves all presidential appointments and ratifies treaties while the house initiates revenue bills.
The Senate has vital powers as stipulated in the constitution under the " advice and consent" provisions, Article II, section 2, to; ratify treaties which require a two-thirds majority of the senators present and a simple majority to approve important public appointments i.e., ambassador and cabinet members.

Answer:
The White Rose (German: Weiße Rose) was a non-violent, intellectual resistance group in the Third Reich led by a group of students including Hans and Sophie Scholl. They attended the University of Munich. The group conducted an anonymous leaflet and graffiti campaign that called for active opposition to the Nazi regime. Their activities started in Munich on 27 June 1942, and ended with the arrest of the core group by the Gestapo on 18 February 1943.[1] They, as well as other members and supporters of the group who carried on distributing the pamphlets, faced show trials by the Nazi People's Court (Volksgerichtshof), and many of them were sentenced to death or imprisonment.
Hans, Sophie Scholl and Christoph Probst were executed by guillotine four days after their arrest, on February 22nd, 1943. During the trial, Sophie interrupted the judge multiple times. No defendants were given any opportunity to speak.
