Life would not exist. The ozone layer is keeping all the gasses from escaping into space. So, without the ozone layer, there would be no oxygen for animals or carbon dioxide for plants. The ozone layer also reflects space radiation and harmful UV rays back into space, preventing them getting into the Earth's atmosphere.
Science study the life cycle of pathogens in order to find a way to interrupt the course of disease and spread of infection. Scientist study the life cycle of microorganism in order to find a way to cancer and other chronic illness.
Explanation:
The life cycle of microorganisms causing disease in the human is studied to know what agents or antibiotics would stop their activity. There are techniques used such as chemotherapy to kill the invading viruses. The antibiotics are made this way to stop bacterial growth. The agents would be invented to put stop at the particular phase of the life cycle to inhibit growth of the pathogen. It would get convenient to make agents if at immune level it is known what phase of their cycle is reactive.
Answer:
The correct answer is A. The statement is true.
Explanation:
Muscle obtains ATP from glycolysis. When exercise conditions are anaerobic, glucose is degraded to lactate. Lactate is exported into the circulation and is taken up by the liver. The liver synthesizes glucose again from lactate via the gluconeogenic pathway. These two metabolic pathways that allow the coupling of the function of two tissues is what is known as the Cori cycle. The energy cost is 4 P bonds / each glucose that travels both glycolytic-gluconeogenic pathways.
