Q. What are the different ways in which glucose is oxidised to provide energy in the various organism ? Q. How is oxygen and carbon dioxide transported in human beings ?​

[1] Aerobic respiration : In this case, pyruvate is broken down into water and carbon dioxide along with release of energy. It commonly occurs in mitochondria of cells.

Anaerobic respiration : In aerobic respiration break down of pyruvate takes place in presence of oxygen to give rise 3 molecules of carbon dioxide and water. And pyruvate is converted into ethanol and carbon dioxide.

[2] By following ways O2 and CO2 transported through human body:

it creates acid rain

i think it is d. objects resist changes in their state of motion.
