There are two sets of nerves in your skin. The first type are somatosensory neurons that send sensory information to your central nervous syste. The second set consists of autonomic fibers that control smooth muscle in the skin and the blood vessels in the skin.
The correct answer among the choices provided is option A. Lung capillaries are responsible for exchanging carbon dioxide for oxygen from the air. Blood that comes from the heart gets oxygen from the alveoli. The carbon dioxide in the blood goes into the alveoli at the same time.
Since our bodies are made up of 70 percent water, we need water to keep us from dehydrating, food is important because it has the nutrients and proteins that our bodies need to repair, grow, and keep healthy, and oxygen is also important because it gets carried throughout our blood stream and oxygenates our muscles, without any of these, we would die within a few weeks
Hey there!
Here is a paraphrased version of the text:
Objects that are nonliving never had the qualities of life, and never will. Things that are dead did have an experience to have the qualities of life, but then they eventually die, they fail to keep some of the characteristics. So in science, dead is not an identical word to nonliving. A rock is nonliving, a fallen tree is dead, and a moose is living.
Note: While paraphrasing a text, a good thing to do is to think of as many synonyms of the words in the text as you can.
Hope this helps you.
Have a great day!
