The level of carbon dioxide in the blood affects the breathing rate. it also affects the heart rate. how would you expect high levels of carbon dioxide to affect the heart rate?

If there is a high level of carbon dioxide in the blood, the breathing rate would be higher, which makes the heart rate higher as well.

the answer would be roots! roots are the parts of the plant that are underground, and that's how they'd anchor the plant. the stem is above the sol, which doesn't with anchoring. hope this !

you should seek treatment when you are seriously thinking of sui.cide, and that can eventually lead to your own death.
