Oxygen
Oxygen is the final electron acceptor, no part of the process - from the Krebs Cycle through the electron transport chain- can happen without oxygen. Aerobic respiration is complete
If think about it if it was asexual then it came from 1 parent so it would be W
I am confused as to what your question is specifically asking but the chemical formula for aerobic respiration is:
Oxygen + Glucose --------> Carbon Dioxide + Water
O₂ + C₆H₁₂O₆ --------> CO₂ + H₂O
Hopefully this will aid you in answering your question :)
B
A convergent boundary is an earth where two or more lithospheric plates collide
