Uptake of O2 by the blood in the lungs is controlled primarily by----.the PO2 of alveolar air.
option D is correct.
How o2 is transported in the blood mainly by?
Hemoglobin is the primary carrier of oxygen in humans. Approximately 98% of total oxygen transported in the blood is bound to hemoglobin, while only 2% is dissolved directly in plasma
Where does oxygen bind to hemoglobin?
. Oxyhemoglobin is formed during physiological respiration when oxygen binds to the heme component of the protein hemoglobin in red blood cells. This process occurs in the pulmonary capillaries adjacent to the alveoli of the lungs.
How is oxygen transported in the blood ?
-Most O2 is transported by hemoglobin as oxyhemoglobin (Hb—O2) within red blood cells. -the heme portion of hemoglobin contains four atoms of iron, each capable of binding to a molecule of O2. -oxygen and hemoglobin bind in an easily reversible reaction from form hemoglobin

Answer:
A) A process that moves molecules from high concentration to low concentration.
Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Some of the positive particles aimed at a gold foil seemed to bounce back which gives information to the scientists that some heavy particles present in the center of the atom which bounce back the positive particles. so from this evidence the scientists says that atom is divisible and having subatomic particles such as proton, electron and neutron. Proton and neutron is present in the center whereas electron is revolving around the nucleus of an atom.
