Hi
<span>Firstly, the white blood cells tend to have a higher surface to volume ratio then other cells because the are more amorphous. That would lead to an relative increase in plasma membrane, which contains receptors for identifying antigens. Thats why, the white blood cells may be more receptive to detection of antigens due to a higher surface-to-volume ration. It's basically because this.</span>

Explanation:
In the lungs CO2 is removed from the blood and send out the body where we exhale
<h3>ANS.》i.] Light-Dependent Reaction - In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.</h3>
<h3>i.] light independent reactions - The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction cycle of photosynthesis are the chemical reactions that convert carbon dioxide and other compounds into glucose. </h3>
The correct answer is (b) <span>They can be directly observed.</span>
