Answer:
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
Darwin's finches are a classical example of an adaptive radiation. Their common ancestor arrived on the Galapagos about two million years ago. During the time that has passed the Darwin's finches have evolved into 15 recognized species differing in body size, beak shape, song and feeding behaviour.
Answer:
Each biome has a unique set of environmental conditions and plants and animals that have adapted to those conditions. The major land biomes have names like tropical rainforest, grasslands, desert, temperate deciduous forest, taiga (also called coniferous or boreal forest), and tundra.
Explanation:
A biome is different from an ecosystem. An ecosystem is the interaction of living and nonliving things in an environment. A biome is a specific geographic area notable for the species living there. A biome can be made up of many ecosystems. For example, an aquatic biome can contain ecosystems such as coral reefs and kelp forests.
Answer: Shale changes into Slate.
Explanation:
Shale is a sedimentary rock, formed by the deposition and compression of clay and silt.
Shale layers is buried deep into the earth through the process of deposition (i.e the laying down of rock forming material by natural entities like glaciers, wind, and water).
Temperatures and pressures rise greatly because the shale’s layers are buried. When the temperatures and pressures become higher. The shale is changed into a metamorphic rock (with dark brown streak), called Slate.
B.) Cohesion
Explanation:
The best term that fits the description of the term surface tension of water is cohesion.
Cohesion is the intermolecular forces that holds together the particles of liquids and solids.
- Surface tension is a phenomenon in liquids that causes them to come together more and shrink on the surface.
- Surface tension is made possible by cohesive forces between water- water molecules.
- Adhesion is between different molecules like water and glass.
- In capillary action, a liquid is able to rise up in a column
- Sublimation is a phase change from solid to gas.
