Answer:
Pulmonary veins
Explanation:
In the circulatory system, the heart is responsible for for pumping oxygenated blood throughout the body and deoxygenated blood to the heart.
Normally all veins carry deoxygenated blood. However the pulmonary vein is the only vein that carries oxygenated blood.
They carry oxygenated blood from the lungs to the heart.
However the Superior and inferior vena cava are responsible for delivering deoxygenated blood to the heart.
Answer:
The green pigment that traps the energy of sunlight for photosynthesis is called chlorophyll.
Answer:
Explanation:
Two reactions take place that produce raw materials for the dark stage:
- Light energy splits the water molecules into <em>hydrogen</em> and <em>oxygen</em>
- This process is called <u>photolysis </u>
The hydrogen is taken up by a hydrogen acceptor called Nicotinamide adenine dinucleotide phosphate (NADP) while oxygen is released as a by-product .
2 H₂O(l) --------->light energy -------> 4 H + O₂ (photolysis
)
Light energy strikes the chlorophyll molecules and sets in motion a series of reactions resulting in the production of a high energy molecule called <em>Adenosine Triphosphate</em> (ATP)
Hope this helps.
