Answer: ADAPTIVE COLORATION
Explanation:
Colour and colour patterns play an important role in adaptations of animals. Such adaptive coloration is due to the presence of pigments in cells called CHROMATOPHORES. These cells are involved in coloration and color change which helps an animal to look like another animal to stay protected from predators.
Adaptive coloration may be grouped into :
--> WARNING COLORATION: some animals display bright colours and patterns that announce their presence rather than conceal it. Example is the yellow and black stripes of yellojackets and other wasps which have very painful stings.
--> MIMICRY: colours and patterns are used extensively by mimics. For example, the foul-tasting Actaea butterfly and the poisonous African monarch are mullerian mimics. They resemble each other closely because they have similar colouring and patterns on their bodies.
--> CONCEALING COLORATION: This is used in camouflage. It helps an animal to remain unnoticed by the predator. Certain animals change the colour of their body surfaces to match their environment and so escape detection.
The railroad industry used coal to power steam engines, allowing businesses to build more factories for the production of goods.
Explanation:
It is also during the 1800s that the use of coal power enabled the smelting of iron and steel, in addition to the powering of steam engines. Coal and steam engines enabled the building of railroads to transport goods from industries.
Before the discovery of coal in the 1600s, energy was sourced from water wheels and the burning of biomass.
In addition. 1950s saw coal production decline to its lowest levels because it was overtaken by petroleum as the main source of energy.
