Why anaerobic respiration is rapid than aerobic respiration
Answer:
The amount of pressure that is released.
Explanations:
Aerobic respiration is known as a major advantage, base of the amount of energy it releases. Aerobic respiration releases more energy than anaerobic respiration, causing it to become more rapid.
Answer:
Anaerobic respiration is a shorter process than aerobic respiration so a complete cycle of anaerobic respiration is shorter than one of aerobic respiration.
Explanation:
Aerobic respiration involves three stages: glycolysis (the breakdown of glucose into pyruvate), the Krebs cycle (the breakdown of pyruvate into carbon dioxide and hydrogen), and the electron transport chain (hydrogen produced in the Krebs cycle bonding to oxygen to form water).
On the other hand, anaerobic respiration has fewer stages. Anaerobic means 'without oxygen', and so the process takes place without needing any oxygen. In anaerobic respiration, glucose is broken down into pyruvate, just like in aerobic respiration, however due to the lack of oxygen, that pyruvate is broken down into either lactic acid (e.g. in humans), or ethanol (e.g. in yeast). This process is called fermentation, and it doesn't take as long as the Krebs cycle and the electron transport chain, so that's why anaerobic respiration is more rapid than aerobic respiration.

Why is an overabundance of nutrients harmful to a water supply?
A.
It decreases the number and types of aquatic plants.
B.
It kills all aquatic plants.
C.
It sterilizes water.
D.
It causes excessive aquatic plant growth.
Answer:
d
Explanation:
It leads to a process called as eutrophication in which the aquatic plants grow regularly over the water surface and the living beings living inside the water gets diminished because of the lack of nutrients and the various substances required for the growth.
What is water sterilization ?It is the process in which the harmful substances and contaminants are removed outside the water source such that the water can be removed out from water resources such that they can be made appropriate for drinking.
An overabundance of various nutrient primarily nitrogen along with phosphorus in water begins a process known as eutrophication. The process hammers the growth of other lives present on the sources.
Algae feed on nutrients, growing, spreading and turning out the water green. Algae blooms smells bad, blocks sunlight and even releases out chemicals in certain cases.
