Veins are located throughout the body and are responsible for carrying blood and oxygen away from the heart while arteries are responsible for carrying blood toward the heart to repeat the cycle. a. true b. false

This statement is FALSE.

Let's take a quick examination of what type of blood arteries carry and what type of blood veins carry.

Venous blood is 99% of the time DEoxygenated. This means, the red blood cells don't carry the oxygen.

Arterial blood is 99% of the time OXYGENATED. This means, that there is oxygen carried.

(the 1% of the variation is between the pulmonary vein and the pulmonary artery. Those are the ONLY variant and do opposite of the norm.).

Therefore, when our blood is oxygenated after going through the cycle of the heart and lungs, it's pumped out fully oxygenated and through the aorta. The aorta is your superior artery and it branches out from there. The artery's carry oxygenated blood throughout your body. Whereas, after deoxygenation, the veins will carry it back to the heart to get it re-oxygenated.

the calvin cycle has three stages. in stage 1, the enzyme rubisco incorporates carbon dioxide into an organic molecule. in stage 2, the organic molecule is reduced. in stage 3, rubp, the molecule that starts the cycle, is regenerated so that the cycle can continue

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
