Answer:
B
Explanation:
Surface tension allows a water strider to "walk on water"
Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. ( :
Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.

Arteries carry away the blood from the heart, these are the oxygen riched blood and of course the Aorta for that matter since the largest artery is the AORTA. Veins are the vessels that carry blood to the heart (Superior and Inferior Vena Cava)</span>
