Answer:
H2O (Water)
Explanation:
Oxygen (O2) is the final acceptor molecule after the process of aerobic respiration. Specifically, it accepts hydrogen ions at the end of the electron transport chain, the main energy-generating stage of cellular respiration.
This is why oxygen is needed to form large amounts of cellular energy, as without it, the electron transport chain cannot proceed. When oxygen accepts hydrogen ions, it forms water, a byproduct of aerobic respiration.
Answer:
These seven methods include: seed propagation, cutting, layering, division, grafting, budding, and tissue culture technique.
Explanation:
The major methods of asexual propagation are cuttings, layering, division, budding and grafting. Cuttings involve rooting a severed piece of the parent plant; layering involves rooting a part of the parent and then severing it; and budding and grafting is joining two plant parts from different varieties.
Answer:
B
Explanation:
It's NAD+ because if you look at the electron transport chain, NADH delivers its electron to protein 1 (which causes NADH to turn to NAD+) and eventually those electrons move through multiple proteins to finally be accepted by Oxygen. If there's isn't oxygen, NADH won't be able to deliver electrons since those electrons wont end up anywhere. Which means NADH won't be oxidized (lose electrons) to turn into NAD+. NAD+ is necessary in citric acid cycle since it is reduced to turn into NADH.
