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.
Answer: The observation clearly shows that certain behaviors are genetically controlled
Explanation:
From the observation, the Fishers bird uses long strip while the Peach-faced uses short strips and there offspring uses intermediate. It is an indication that the behavior of the length of strips cut by the bird is under genetic control and it can also be concluded that both the Fisher bird or Peach-face bird does not have complete dominance over length of strips cut for nest making.
The correct answer is B) Light intensity. Hope this helps.
