Explanation: Because that’s what US Test Prep said was right.
<u>Answer</u>:
The difference between systemic and pulmonary circulation is the Systemic circulation carries the blood between to the heart and body and the pulmonary circulation carries blood between the lungs and the heart.
<u>Explanation</u>:
Circulation of blood is of two types:
The systemic circulation and The pulmonary circulation.
The Systemic circulation carries the oxygenated blood from heart to the body through the arteries (aorta) and also carries back the deoxygenated blood from the body to the heart through veins (superior vena cava) and pulmonary circulation carries deoxygenated blood to the lungs from the heart and from the lungs to the heart.
In Pulmonary circulation the pulmonary artery is used to carry the deoxygenated blood to the lungs and the pulmonary vein is used to carry oxygenated blood to the heart from the lungs.

Photosynthesis is divided into light-phase and the dark-phase. The former occurs in the presence of sunlight while the latter is independent of sunlight.
Explanation:
The light-dependent phase begins the process of photosynthesis. The energy of the sun is used to split a water molecule into H+ and O- in a process called photolysis. IN the process, two high energy electrons are released and used to replace the ones that left the reaction system of the chlorophyll pigments. The electrons being replaced were conveyed through a protein chain and their energy used to pump H+ ions into the thylakoid from the stroma. The electrons are ultimately used to reduce NADP+ into NADPH. This creates a proton motive force used by ATP synthase to create ATPs – a process called photophosphorylation.
IN the light-independent phase, carbon dioxide is reduced by NADPH to create glucose molecules in the Calvin cycle.
