Answer:
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.
Explanation:
sorry if its wrong
The maximum probable speed of walking is restricted mainly by two factors, that is, the length of the leg and the free fall acceleration. The animals with longer legs exhibit higher maximum walking speed, while the animals with very short legs exhibit low maximum walking speed.
The large birds like pheasants usually walk brief distances, however, birds like chickadees never walk. In the case of pheasants, they exhibit a higher maximum walking speed, on the other hand, the chickadees exhibits a low maximum walking speed. Thus, the chickadees should never walk, they should fly or hop.
Also, more energy is utilized in flying than in walking. Therefore, large birds like pheasants usually walk brief distances so that energy can be saved.
The radical in this question is OH.
The reason this will be a radical, is that the definition of a radical is the presence of an unpaired electron. This causes the radical to be unstable, desperately wanting to do something with the free electron that it has.
Oxygen has a charge of 2-, and Hydrogen has a charge of +1. When you pair them, you end up with a net charge of 1-, which is the presence of that unpaired electron. It will usually be written as: 
Answer:
<em>In electromagnetic waves, energy is transferred through</em> <em>vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.</em>
