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.
Well all of them are pollinated by bees and stems and other things we would not eat would remain
I’m pretty sure the answer would be 4.

Answer:
the oxygen should be concentrated in the alveoli
Explanation:
Diffusion: The movement of molecules from a region og higher concentration to a region of lower concentration.
So when the Oxygen is concentrated in the alveoli only then it can move towards the blood
Diffusion is a passive transport system which means it doesnt need energy in the form of atp molecules
if the molecules move from a region of lower concentration to a region of higher concentration it needs atp molecules which is energy and is called active transport system
