Answer:Cellular Respiration
Explanation:
Cellular respiration is the process by which cells produce energy, and is broken down into three more steps: glycolysis, Kreb’s cycle, and electron transport chain. Glycolysis requires glucose, two ATP, and NAD+, and two ADP, and produces two pyruvate, four ATPs, two NADH, and two H2O. The Kreb’s Chcle and thus the downstream electron transport chain require acetyl-CoA, one ADP, three NAD+, and one FAD, but pyruvate oxidation needs to happen prior to the Kreb’s Cycle, thus this is where the Oxygen is used and produced into two CO2.
Sperms (Pollen is technically a male gametophyte, meaning an organism that makes “gametes”, which in this case is sperm.).
Answer:
There are two ways
1) By the depth at which the fossil was found(i.e. If it was found near the surface of Earth, then its a fossil which was just recently decomposed, but if it was deep inside then it's old.
2) By method of Carbon Dating
Answer:
You would find microscopic bacteria
Moving substances from a lower concentration to a higher concentration requires active transport.
