An organism is discovered that thrives both in the presence and absence of oxygen in the air. Curiously, the consumption of suga
Vinvika [58]

A facultative anaerobe.

Explanation:

Anaerobes are organisms which can produce energy via the process of fermentation in the absence of oxygen. The anaerobes can be classified as facultative anaerobes and obligate anaerobes.

Facultative anaerobes are those which can carry out respiration in presence of oxygen but can choose to follow the fermentation pathway if oxygen is absent. Fermentation also uses glucose.

Aerobic respiration produces 32 molecules of ATP from one  molecules of glucose while fermentation produces only 2 molecules of ATP . Thus when the organism switches to fermentation pathway it utilizes more and more glucose to reach its energy demands.

Considering all the above points we can conclude that observations indicate that the organism is a facultative anaerobe.

Which characteristic of sexual reproduction has specifically favored the surviva of animals that love on land
QveST [7]

Answer:

i think fertilization on the body of the female, could be an answer.

Explanation:

Sexual reproduction re-mixes genes to create "individual differences" over which natural selection acts. Basically, sex is an opportunity for two organisms in the same species to pool their resources. Some of their offspring will carry a beneficial mixture of good genes from both parents. You can even accelerate the pace of evolution.
