The purpose of the Golgi apparatus is to pack and transport these proteins it receives from the other organelles. It is kind of like the mail man or post office of the organelles in a cell.
The change in partial pressure from the alveoli (high concentration) to
the capillaries (low concentration) drives the oxygen into the tissue
and the carbon dioxide into the blood (high concentration) from the
tissues (low concentration), which is then returned to the lungs and
exhaled.
Once in the blood of the capillaries, the O2 binds to the
hemoglobin in red blood cells which carry it to the tissues where it
dissociates to enter the cells of the tissues.
The lungs never fully
deflate, so air that is inhaled mixes with the residual air left from
the previous respiration, resulting in a lower partial pressure of
oxygen within the alveoli.
Answer:
A chemical formula tells us the elements included in the compound. The letters in the chemical formula represent different elements.
This is false. There are many factors, like climate, fires, pollution, etc.
