- Membranes and membrane-bound organelles in eukaryotic cells localize (compartmentalize) intracellular metabolic processes and specific enzymatic reactions. Nuclear membranes act as barriers that prevent the passage of molecules between the nucleus and the cytoplasm. ... The nuclear envelope is filled with nuclear pores.
If it does not start function in very little time the probability is he would die. Because muscles need oxigen to function, which means that the heart won't function, the heart needs to keep pumping blood, etc.
Hope it helps!
Answer
Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
