Oliga [24]

Answer:

anaerobic organisms do not require the presence of oxygen to produce energy in form of ATP, while aerobic organisms require oxygen

Explanation:

Anaerobic organisms produce energy by glycolysis, which is a metabolic pathway that produces ATP by transforming glucose to lactate when oxygen (O2) is limited. Glycolysis produces two (2) molecules of ATP per glucose molecule. Moreover, when O2 is available, aerobic organisms produce ATP by cellular respiration, which includes glycolysis, the Krebs cycle, and oxidative phosphorylation. Cellular respiration is able to produce thirty-eight (38) molecules of ATP per glucose molecule, thereby being more efficient than glycolysis.

-BARSIC- [3]

Answer: The privatization of endangered species will reduce their chances of extinction.

Explanation:

The endangered species are those species which are low in numbers, their population will reduce or extinct in the near future. The privatization of these animals will protect them from dangers of trafficking, predation, habitat loss, and death due to natural disaster. Animals like elephant, monkey, tiger, lion are privatized to protect their extinction.

The trade of hides, teeth, ivory, flesh, horn, and other parts of the endangered animals will accelerate the rate of extinction. Prohibition of trade will allow the agents of trafficking to get chances of killing and stealing animal parts to a large number.

The tragedy of commons suggests that people neglect the well being of the society for personal gain. Those people who exploit the resources from endangered species causing harm to the nature as they are responsible for reducing biodiversity.
