Hello the answer to the question you asked may not be what you are looking for But I'll do the best I can to answer your question.
If you are wanting to know "how does debris form in a mudslide"
then, it forms by debris getting picked up by the mudflow and being carried away by the mudflow itself.
Now if you mean "how does a mudflow form?"
I forms by a excessive amount of rain in that area/place that doesn't happen often or at all. Which causes the ground to not be used to that excessive amount of water so it causes a flooding of water. Now the mudflow happens when that area's soil is very lose so it gets picked up way to easily causing soil (mud) to color the water that dirt's color and be more thick because of the high consistency of mud in it.

Answer:
anaerobic organisms do not require the presence of oxygen to produce energy in form of ATP, while aerobic organisms require oxygen
Explanation:
Anaerobic organisms produce energy by glycolysis, which is a metabolic pathway that produces ATP by transforming glucose to lactate when oxygen (O2) is limited. Glycolysis produces two (2) molecules of ATP per glucose molecule. Moreover, when O2 is available, aerobic organisms produce ATP by cellular respiration, which includes glycolysis, the Krebs cycle, and oxidative phosphorylation. Cellular respiration is able to produce thirty-eight (38) molecules of ATP per glucose molecule, thereby being more efficient than glycolysis.
Answer:
It is true that studying natural selection in the fields can be challenging. Some of the challenges which Darwin might have faced could have been:
Darwin was only studying one trait for his results. But there might have been many other factors or traits affecting natural selection.
Natural selection does not happen rapidly hence Darwin would have had to wait for many generations to observe the results.
The environment is not such an easy factor to study. It is complex. It might have happened that the environment might have changed before any changes were seen in the population of the birds.
