Water stratification is a phenomenon in which regions of water with different properties, such as salinity, oxygen content, density and temperature, form barriers to mixing of the water.
These barriers also create channels, referred to as sound fixing and ranging (SOFAR) channels. In these channels, the sound has a specified path. It travels slower than normal, but due to reduced dissipation to the surroundings, the sound travels for larger distances.
trees do not fix N2 from air they fix oxygen with the help of N2 fixing bacteria . so trees do not fix N2
Answer:
D. Pool temperature
Explanation:
The dependent variable in an experiment is the variable that is measured or responds to another variable called the independent variable. The outcome of the dependent variable is dependent on the independent variable.
In this computer model, the engineers compare which of several pool designs require the least amount of energy to be heated. The TEMPERATURE at which each pool design is heated is dependent on the type of pool design used. Hence, POOL TEMPERATURE is the dependent variable. It is the variable being measured in response to the type of pool design used.
Nitrogen takes steps through the Nitrogen Cycle, taking an active role in the lives of organisms and changing forms to meet their needs. In fact, nitrogen is a critical part of the development of plants, many farmers even add nitrogen to plants to make the grow bigger and more fruitful. Even the human body needs nitrogen to, which is good because most of the air we breath is nitrogen.
