What caused tree trunks of many trees in England to turn from a light color to a dark color?

The industrial revolution in England (the black smoke form all the factory chimneys) produced allot of environmental pollution and the trees in the worst affected areas were covered in soot. Now thankfully this pollution has ceased and the tree trunks are no longer black...I understand that the areas of black peppered moth variants are now reverting to the light colored variety.;)


Which tpe of selection occurred among the peppered moths of England following the Industrial Revolution that stained londons tree trunks dark brown?

The peppered moths of England underwent directional selection following the Industrial Revolution. Prior to the pollution caused by industrialization, lighter-colored moths were more common and better camouflaged on the light-colored tree trunks. However, as pollution darkened the tree trunks, the darker moths had a survival advantage and their population increased.

Why the event horizon of a black hole stop the light from getting rid of that?

The event horizon is the point of no return around a black hole where the escape velocity exceeds the speed of light. Light cannot escape from beyond the event horizon because the gravitational pull is so strong that even light cannot overcome it. This is why the event horizon appears to "trap" light within the black hole.


Why don't ocean plants have thick trunks?

Ocean plants do not have thick trunks because they do not need to support themselves against gravity like land plants. The buoyancy of water supports their structure, allowing them to grow tall and thin to maximize light absorption. Thicker trunks would require more energy to build and maintain, which is not efficient in the underwater environment.

Why do trees in tropical rainforests have tall straight trunks?

Tree trunks are straight and branchless Tree trunks are straight and branchless in the rainforest because, so that they can grow tall. As their efforts can be on growing tall not having branches near the bottom. More water falls down on the top of the tree. Therefore,they put their efforts in growing tall so that gain most water. Simply, the trees are close together and grow towards the light only the tops receive light so the lower branches die off because of lack of the aforesaid light. The water supply to the trees is drawn up by the roots.
