The answer is D. energy needed to break chemical bonds
The electron transport chain (ETC) is the final step of cellular respiration and takes place in the mitochondrion.
- The final step in cellular respiration is the electron transport chain. This is sometimes abbreviated as ETC. ETC needs oxygen, which means aerobic process. It occurs at the edges of the inner lining of mitochondria. These handles are called cristae.

Answer:
Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Explanation:
All the three options given can cause checkpoint genes to interrupt cell division.
Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.
Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.
Answer:
Describe the properties of carbon that lead to wide variation in organic compounds?
Carbon is able to to have wide variation in organic compounds as a result of it allotropic property as it is the only element because of the ability to form four types of bonds.
