Answers

Answer: Hind wings have tail extensions.

Explanation:

The dichotomous key is a tool which is used by the scientists to identify the unknown living organisms by comparing the observable characteristics of unknown with known living organisms. It stresses to identify the organisms or species by their scientific names and every species has a particular scientific name. Hind wings of butterfly is the observable characteristic which can be compared with that of other known butterfly species that also have a tail extension. This physical characteristic will help in identification of butterfly.

Cells that live in environments where oxygen is present only a small amount of the time have two options to survive. They can be obligate anaerobes, which are poisoned by oxygen and do full cellular respiration with an electron transport chain that ends in a different molecule than oxygen (such as sulfur.) Alternatively, they can be facultative anaerobes that do full cellular respiration with oxygen when oxygen is available but do fermentation with glycolysis when oxygen is not available. Full cellular respiration makes 32 ATP per glucose. Glycolysis makes only 2 ATP per glucose. Write out which option you think is better in an environment that only occasionally (rarely) contains oxygen, obligate or facultative anaerobe, and defend your answer.

Answers

by defending the answer is that aerobic respiration is used by oxygen but anaerobic respiration is not used by oxygen also plants they do survive at night but human being cannot breathe the same air with plants at night because oxygen take place but at the daytime we use carbon dioxide this is how I do understand in my understanding
