When a person is awake their brain is more alert and aware of it's surroundings. When a person is asleep their brain is slower at receiving and processing the sound waves.
Hope this helps!
Answer:
The pulmonary artery carries oxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveolar and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.
Explanation:
Because a single celled organism is not as adapted to the tasks at hand and is not as effective as a multi-celled organism. Having a multi-celled organism, specific cells in his body can perform specific tasks which grant him a faster exeuction time of these tasks as opposed to a single-celled organism.
The answer is m.
Centripetal force (F) is a force that makes body move around a circular curve. The unit of force is N (N = kg * m/s²).
It can be represented as:<span>
</span><span><span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> <span> </span></span></span></span></span></span></span></span></span></span></span></span> <span> </span></span></span><span> </span></span><span>
where:
m - mass
v - velocity
r - radius of the curve
We have:
m = 1,200 kg
V = 20 m/s
F = 6,000 N = 6,000 kg * m/s²
We need radius of the curve:
r = ?
So, if </span><span> </span><span>, then:
</span><span> </span><span>
</span>⇒ <span> </span><span>
</span>⇒ <span> </span><span>
</span>⇒ <span> </span><span>
</span>⇒<span> </span><span> </span>
The more closely related the organisms, the more similar the bond structures. Many mammals , for example, have similar limb structures. The rabbit is similar to the human arm, with a large upper bone "arm" (the arm in humans) and a lower part of two bones, a larger bone on one side (the radius in humans) and a smaller bone on the other side (the ulna). These species also have a collection of smaller bones in the wrist area (called carpal bones in humans) that lead to the "fingers" or phalanges
