write a short essay on what you have learned about communication that surprised or had an impact on you​

Answers

I learned many things about communication there are many’s types of it and many ways how to do it. The first thing that surprised me is when I was 4 I was surprised when you can communicate on a device like texting I know I know. Now I learned many types of communication like angry, happy, sad, and much more which I find pretty cool for some reason. Now you can do communication in so many ways like art, devices, mails, or just talking to someone. Communication made a big impact on me is because without out I wouldn’t be able to talk and text or anything. I would just be confused. Communication is really important to our world like we can learn new languages or new stuff like when your on zoom and your teacher ask you a question you communicate to answer.

Answers

The correct answer to this open question is the following.

You did not include the list of activities, so we do not know what you are talking about. However, doing some research we can comment on the following.

Here is a list of activities that is probably the one that is part of your question.

Exercise: every two days. I take one day off.

Breath clean air: Twice a week. Saturday and Sunday. During the week I live in the city because I have to go to campus and there is a lot of traffic and most of the week there is pollution in the air.

Chat with friends: daily, all the time. I like to be connected as much as possible.

Biking: not so much. I'd rather go jogging at night. It is less polluted by night, and many people like to run in the park under the moon.

Enjoy the natural landscape: on weekends, when I go to the country.

Enjoy peace and relaxation. Not so often. But I am really interested in Yoga classes.

b. adaptation

c. recovery

Why is the tracheal wall supported by rings of cartilage?
to allow for the exchange of gases in the lungs
to trap remaining particles that have slipped through the upper respiratory tract
O to stop foreign objects from entering the airways
to prevent the airway from collapsing while air flows through it

Answers

Answer:

Tracheal wall is supported by rings of cartilage to prevent the airway from collapsing while air flows through it.

Explanation:

The trachea is a structure that forms part of the respiratory system, between the larynx and the main bronchi, allowing air to pass into the lungs.

Structure of the trachea is formed by a series of incomplete cartilaginous rings that prevent the collapse of this structure during respiratory activity.  The catílage is a firm and at the same time flexible tissue, which allows in the trachea the expansibility but avoids the closing of this important airway.

The other options are not correct because:

Allow the exchange of gases in the lungs is a function of the alveoli.Trap remaining particles that have slipped through the upper respiratory tract is not a function of trachea.Trachea is not capable of trapping foreign bodies.

Title: ("Sunday at the Water Park") "Yeah, the job is pretty boring," Mariah admitted, looking at the wave pool from atop her lifeguard station. " But I get to be outdoors, and I can go on all the rides for free when I'm done." Her questioner - Berry, a classmate she didn't know well, who happened to be a customer as well as being the annoying editor of the school newspaper - stretched his arm up toward her in some weird kind of salute. Actually he was recording her with the purple-and-black striped phone in his hand. " How are the working conditions?" he inquired in the important tones of an anchorman. "They're -" She stopped cold. She stood up, staring at the crowd who rose and fell and squealed with each new surge of machine-churned water. Amid the bobbing figures, she had seen one stop moving, and seen its head sink halfway under the water and stay there. She grabbed the rescue tube and dove into the pool. In what felt like an instant, she had swum to the far end, a few feet from the wave machine, and stopped behind the eight-year old boy who was floating face -down. She thrust the long, red foam rescue tube at him. Then, she stood in the three-foot deep water and scooped him around the waist. As she lifted his head, a waterfall of clear, bubbly water streamed down. She wrapped both his small, soft hands around the flotation tube and towed him to the side of the pool. She hoisted him high and set him on the brightly painted white cement, then boosted herself up after him. The boy-his name turned out to be Peter-hadn't fully lost consciousness, so he didn't need CPR. After a couple of slaps on the back, he was coughing wetly and breathing well, though too stunned even to ask what had happened. By now, the waders in the pool understood vaguely what had happened. They looked around helplessly and asked each other bewildered questions. No one had noticed that Peter was drowning, not even the adults three feet away from him. Peter's teenage brother and his friends had sloshed as quickly as they could to poolside. In five minutes, the EMS ambulance arrived to take Peter to the nearby clinic. " I got it all on video!" Berry exclaimed. " Now give me an interview!" She couldn't give him much of an interview, because the event had lasted only thirty seconds. She hadn't consciously decided how to act and didn't remember many details. Her reflexes had done it all automatically. Her lifesaving courses had worked! She hardly knew what she was saying during the interview and assumed she must sound incredibly dumb and out of breath. Later her family and neighbors told her how poised and in-charge she'd appeared. The strange thing was, she didn't feel as if she'd done anything special. The only thing that felt new was the way she couldn't keep herself from smiling at everything - at the trees in her backyard, at silly TV shows, at her younger brother, at the table setting at dinner, at everything.
