Some jellyfish are transparent, how will this affect their ability to survive?

Answers

So predators cannot see it as well

Explanation:

It will affect their ability to survive because...since Jellyfish bodies are transparent, that means they are less visible to predators or threats. Which will affect their way to survive because since they are less visible to predators, it gives them a better chance for survival since their predators can't see them very well. It also gives them a better chance for survival because hunters won't be able to see them well enough to catch them because they blend in with the water, which is called transparent.

Respiration taking place in presence and absence of oxygen has different end products. Aerobic respiration has the end products as carbon dioxide and water, alcohol is the end product of anaerobic respiration.

What is respiration ?

It is the process in which the complex substituents are broken into simpler products in the presence of oxygen and absence of oxygen in  order to produce energy.

In the aerobic respiration processes like glycolysis takes place where the glucose breaks down into 4  molecules of ATP with the consumption of 2 ATP molecules. 1 glyceraldehyde molecule is produced from the glucose that is 2 glyceraldehyde molecules are produced. Total of 4 ATP are produced.

Alcoholic fermentation is the anaerobic respiration that says the anaerobic respiration where the glucose is broken down into alcohol and water. In the anaerobic respiration, excess of alcohol gets broken  down into lactate.
