anaerobic respiration.
Due to anaerobic respiration, one by- product of this process is lactic acid which builds up in the muscles and causes the fatigue.
Thats the short answer, I don't know if you want more details such as using the equations of both types of respiration, etc.
Answer;
The amount of water and the temperature of the water and the angle the bottle was set in.
Explanation;
The two main variables in an experiment are the independent and dependent variable;
-An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example; the dependent variable in tornado in a bottle is the amount of water and the temperature of the water and the angle the bottle was set in.
Answer: These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.

An organism reacts to changes in its environment. this is called Behavior
Answer:
Xylem cells have no cytoplasm or end walls, meaning they form a tube through which water can pass freely to allow water transport. Lignin strengthens the cell walls, helping to support the plant.
