I think the part of the brain that stores stressful experiences as negative emotional memories is the LIMBIC SYSTEM.
The limbic system is the c<span>enter of our emotions, learning, and memory. </span>It is composed of the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus. All parts of the brain.
What organism? If its plants, they give oxygen during the day and carbon dioxide in the night. While animals give carbon dioxide but take oxygen from the air. These carbon dioxide gas and oxygen gas go to the atmosphere and affect the carbon cycle and oxygen cycle.
Here is the cycle if you want to know more
Plants (give out oxygen) -> Animals (Use oxygen) + (given our carbon dioxide) -> plants (take oxygen)
and so on
Answer:
I can’t answer all of them, but I’ll answer the oxygen ones.
The mitochondria uses oxygen. In mitochondria, this process uses oxygen as a waste product. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.
I hope this helps, even though I only answered 3 of your questions!!
