Answer:
b. Capillaries; veins; arteries
Explanation:
Capillaries are the blood vessels with very thin walls. They serve as a site for an exchange of substances such as respiratory gases, nutrients, and toxins between the blood and the cells of the tissues. Veins are the blood vessels that mostly pick the deoxygenated blood from the body cells and deliver it to the heart for oxygenation. On the other hand, arteries are the blood vessels that mostly carry the oxygen-rich blood. They pick the oxygenated blood from the heart and deliver it to body cells. Therefore, veins carry blood towards the heart while arteries carry it away from the heart.

Marble and limestone are especially vulnerable to acid rain. This is because the two building or construction materials contain calcite which is easily dissolved by acid.
Concrete surfaces and paint finishes are also seriously damaged by acid rain.
Answer:The process of photosynthesis is energy-releasing because the process converts light energy into free energy that can be
used for cell functions.
Explanation:
Photosynthesis is a process used by green plants to convert light energy into chemical energy that is later released to fuel the organisms' activities. ... In these light-dependent reactions, some energy is used to release electrons from suitable substances, such as water, producing oxygen gas.
