-Are the Galapagos finches and those on the mainland the same species?
Explanation:
- When Darwin visited the Galapagos islands he observed that the small flocks of finches that existed there were very similar to the finches that existed in the mainland of South America except for their beak shape and feeding habits.
- This prompted him to ask the question that 'Are the Galapagos finches and mainland finches the same species?'
- Later on studies made it evident that a few groups of mainland finches migrated to the Galapagos island and occupied different niches.
- They adjusted themselves to the island environment and evolved with new adaptations in beak structure and feeding habits.
- They are now classified into 14 groups out of which 13 exist in the Galapagos island.
- The Galapagos finches are divided into three groups: the ground finches, tree finches and Warbler finches.
<u>Sediment</u> is formed as a result of interaction of igneous rock with wind and water over a long period of time.
<u>Explanation</u>:
An igneous rock is formed by the weathering of the molten earth material. If the igneous rock is continuously exposed to wind and water for long time then the fragments of the rock will get loosened. This causes the fragment to fall off and sediments will be formed.
Sediment is a material that is broken off from the rocks due to specific weather condition. As metamorphic rock requires high temperature or high pressure for its formation, it cannot occur with the interaction of wind and water.
Answer:
Explanation:
Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.
