Again, this is important since whether M is bound or free will govern its activity. To determine KD, you need to determine ML and L at equilibrium. How can we differentiate free from bound ligand? The following techniques allow such a differentiation.

The six most common elements associated with organic molecules—carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur—take a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth’s surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials.

(Note that this term can also refer to artificial lakes created by dams.) Water is found as a liquid on the surface (rivers, lakes, oceans) and beneath the surface (groundwater), as ice (polar ice caps and glaciers), and as water vapor in the atmosphere.

Terrestrial biomes are based on land, while aquatic biomes include both ocean and freshwater biomes. The eight major terrestrial biomes on Earth are each distinguished by characteristic temperatures and amount of precipitation. Comparing the annual totals of precipitation and fluctuations in precipitation from one biome to another provides clues as to the importance of abiotic factors in the distribution of biomes

As rain falls through the atmosphere, sulfur dioxide (SO 2 ) in the atmosphere is dissolved in the form of weak sulfuric acid (H 2 SO 4 ), creating acid rain.

Water is found as a liquid on the surface (rivers, lakes, oceans) and beneath the surface (groundwater), as ice (polar ice caps and glaciers), and as water vapor in the atmosphere. Water reservoirs are the locations where water is stored. The hydrologic cycle describes how water moves around the world between different reservoirs and forms.

As warm moist air rises higher into the atmosphere it cools. Cool air can't hold as much moisture as warm air so the moisture condenses into clouds and eventually rain or snow. Forests tend to dominate these areas of the globe. By the time the air sinks back towards Earth's surface it has lost most of its moisture and as a result, these regions of the globe tend to be dominated by deserts or other dry land
