The reason for the loss of color after the industrial revolution is that the light-colored moths were "selected against" by predators. These birds could only see the light ones against the newly dark, sooted background. Over time, these predators could no longer distinguish the dark ones from their natural dark, sooted background. Thus more light-colored moths stood out against the dark soot, and were eaten. And more dark-colored moths eluded the birds, survived to reproduce, passing on more of their dominant genes for dark color to their offspring. After several decades of hundreds of thousands of generations, most of the later generations were dark, due to selective advantage of camouflage to survive predation.
Answer:
Many organisms found on reefs produce chemical compounds that have been used in treatments for cardiovascular diseases, ulcers, leukemia, lymphoma, and skin cancer, and many more remain undiscovered.

hope this helps... but maybe not so sorry if im wrong :(
Rock cycle- the prices in which rocks undergo in the earths crust, involving igneous instruction, uplift, erosion, transportation, deposits as sedimentary rock.
Tectonic cycle- the movement of large portions of earths crust (plates) the driving forces that move these plates are a combination of events that occurs within the earth.
Water cycle- the path of all water followers as it moves around earth in different states, water vapor, ice, water...
Carbon cycle- series of processes by which carbon compounds are inverted in the environment involving the incorporation of carbon dioxide into living tissue by photosynthesis.
Nitrogen cycle- series of processes by which nitrogen and is compounds are introverted in the environment and living organisms.
Phosphorus cycle-biochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
