The respiratory system is a collection of organs involved in carrying out gas exchange in your body. Deep in the lungs, tiny sacs called alveoli take in oxygen from the atmosphere and release carbon dioxide.
Answer: The main function of Cellular respiration is to convert glucose into energy source (ATP).
Explanation: Cellular respiration is process in which chemical energy of food is released and turn into ATP. This process incudes three steps: Glycolysis, Kreb Cycle and electron transport chain.
Glucose can not be directly used as energy. By the process of Cellular respiration 1 glucose molecule gives 38 ATP molecules.
The answer would be (B) because the pair of Guanine is Cytosine and the pair of Adenine is Uracil (It is paired with Thymine in DNA).
If I remember correctly it should be translocation mutations. But I do not see it as one of the options.
