A vein. This is because veins carry deoxygenated blood back to the heart.
Answer:
The right and left subclavian vein.
Explanation:
It is known that lymphatic vessels flushes the tissues, collecting waste products, bacteria, and damaged cells, and then drains as lymph into "left and right subclavian vein".
Actin, Intermediate filaments, and Microtubules are all cytoskeletal protein filament. Primary filaments are not.
In the roots of the plant, oxygen is taken in for respiration, which happens in Mitochondria. It helps render the energy for active transport in the uptake of nutrient from the soil. In the foliage, carbon dioxide is taken in for the process of photosynthesis.
The carbon dioxide is chemically bonded with hydrogen from the splitting of a water molecule to form carbohydrates. In the splitting of the water molecule, the oxygen atoms are combined in a molecule and respired out of the plant.
You would expect plants to have leaves with little surface area, and develop a different form of carbon storage during photosynthesis that better suits these environments like CAM or C4. They would also have thick cuticles to prevent water loss. Plants in the tundra and the desert generally adapt by growing as low-lying shrubs.
