The answer is <span>C. glycolysis, Krebs cycle, electron transport</span>
Cellular respiration includes glycolysis, link
reaction, Krebs cycle, and electron transport chain (ETC), in that order. The
main function of ETC is a production of ATP. In this series of
oxidation-reduction reactions, electrons from the previous stages of cellular
respiration are taken and transported to the oxygen which is the final acceptor
of electrons. As the result, water and ATP are produced.
Look up traffic rules on whatever state you live in and it will tell you everything :) not much of an answer but thats all i have <3
Natural Selection is the process of those who have not evolved over time to be picked off by either predators or the environment. Evolution is the result of a species being altered in some way to adapt to their new environment to survive.
This is only one part of the answer, but its important: high-altitude O2 absorbs much energy from the sun (including radioactivity), which forms the ozone layer. this process protects delicate molecules important to life - most notably dna
