If we take the example of sun and water (sea or ocean).
Light from the sun is attenuated by the atmosphere before reaching the surface of the water; underwater, the attenuation is considerable, infrared is absorbed in the first meter and light reaches 100 meters. Beyond 1000 meters is the dark night.
As in all environments, two phenomena contribute to the attenuation of light: Absoption and diffusion.
The absoption of light in the sea is the absorption of photon energy by energy level transition of the atoms and molecules that make up seawater.
Light scattering is a physical phenomenon that occurs when optical inhomogeneities of the medium cause random changes in the direction of the light rays.
The attenuation of light under water is mainly due to absorption, the diffusion being of less importance.
They take place in cells in the body
Hmmm i think its the third one because men only have 1 x chromosome therefore without the other one if the x chromosome on a men carries a disorder it will show because there is no other chromosome to balance it out and in women the disorder has to show on both X chronosome (and its rarer) for a disorder to appear therefore women having a second X chromosome is effectively a protection
The impact of human societies greatly <em><u>started following the </u></em><em><u>industrial revolution</u></em><em><u> in the 1800s which increased in further at the half of the 20th Century.</u></em>
The human society through industrial revolution that began after the World War II started having a huge negative impact on the environment and the climate. This gave rise to climate change and other challenges faced in our contemporary world.
Production and use of industrial chemicals boomed. Agricultural and pharmaceutical chemicals are implicated in altering the environment as heavy use and their impacted were recorded at the half of the 20th century.
Pollutants from industries and farms become more pronounced at the period even up till now.
Therefore, the impact of human societies can be said to have greatly increased <em><u>in the </u></em><em><u>post-World War II period</u></em><em><u> in the 1800s as a result of the </u></em><em><u>industrial revolution</u></em><em><u> up to the half of the 20th century.</u></em>
