The right option is; nucleus
Nucleus is the organelle that controls information in the cell.
Nucleus is the most prominent membrane bound organelle that is situated within all eukaryotic cells. The nucleus controls all the activities of the cell and it contain most of the cell's genetic material (DNA). The nucleus is surrounded by a double membrane (nuclear envelope) which maintains the shape of the nucleus, and keeps the nucleus contents from the cytoplasm.
This was answered else where on Brainly, and this is what they said,
"Most proteins in the living organisms are enzymes and they required specific optimum conditions in order to function optimally. Disruption in the homeostasis will leads to deactivation of these proteins. For instance, if the temperature needed for a protein to work optimally has been exceeded, the protein may be denatured and will be unable to perform its needed functions, this may result in several adverse effects in the organism."
That would be integumentary system
Oxygen is absorbed by the blood in the capillaries that surround the alveoli
