Answer:
correct option is corridors
Explanation:
we know that here in the ecology
to counter habitat fragmentation corridors are being constructed
so here we can say that corridors is a functional component of wild life
it is associate with megafauna whose population they are designed to conserve and Corridors is critical for the maintenance of ecological process
including allow for movement animals and viable populations
regional corridor is primary land scape connection between the large area of habitat
so we can say correct option is corridors
i. Using fossil evidences
ii. Similar rock lithologies at the edges of continent
iii. Climate clues
iv. Fitting of the continents into a puzzle
v. Sea floor spreading
Explanation:
Pangea was a super-continent on the earth which formed about 330 million years ago during the Paleozoic and began breaking up during the early Mesozoic, about 175 million years ago.
Most of the present day continents formed as a result of the separation of the Pangea in the early Mesozoic.
The first scientist to propose the existence of this super-continent was Alfred Wegener in 1912. He suggested the continental drift hypothesis to explain the separation of the land masses.
Today, the theory has been revised to the theory of plate tectonics which provides a better mechanism to understand the drifting of the continents.
Here are some of the evidences to support the existence of Pangea;
- Using fossil evidences: Mesosaurus, a reptile animal that lived during the Permian, was found in both South America and Southern Africa. Since this animal could not swim nor fly, only a jointed landmass could have made them present in both continents.
- Similar rock lithologies at the edges of continents: rock formations at the Western edge of Africa and South - Eastern part of Brazil matches with one another and have been believed to be once joined together.
- Climatic clues such as glacial tills that are confined to temperate and polar regions have been found in tropical regions.
- Wegener fitted the present day continent into a giant supercontinent and this provided a visual support for his claim.
- Evidences from sea floor spreading revealing magnetic reversals at divergent margins suggests the prevalence of plate tectonics i.e moving plates on earth.
This among many other evidences underscores the existence of a supercontinent called Pangea.
White fur not only provides camouflage in winter but adds warmth. A pigment called melanin, absent in white fur, gives the fox its brown summer coat.
<h3>
What is camouflage?</h3>
Camouflage is a defense mechanism or tactic that organisms use to disguise their appearance, usually to blend in with their surroundings.
The hair shafts of white fur are hollow, trapping warm air from the animal's body heat and acting as insulation much the same way as a down coat does for a human wearer.

Answer:
The European Union is a political and economic union of 27 member states that are located primarily in Europe. Its members have a combined area of 4,233,255.3 km² and an estimated total population of about 447 million. The EU has developed an internal single market through a standardized system of laws that apply in all member states in those matters, and only those matters, where members have agreed to act as one. EU policies aim to ensure the free movement of people, goods, services and capital within the internal market; enact legislation in justice and home affairs; and maintain common policies on trade, agriculture, fisheries and regional development. Passport controls have been abolished for travel within the Schengen Area. A monetary union was established in 1999, coming into full force in 2002, and is composed of 19 EU member states which use the euro currency. The EU has often been described as a sui generis political entity.
Some of the rights afforded to EU citizens include the Following.
The right to vote and to stand as a candidate at elections to the European Parliament.
The right to vote and to stand as a candidate at municipal elections.
The right to good administration.
The right of access to documents.
The right to petition.
Freedom of movement and of residence.
Diplomatic and consular protection.
