I am pretty confident that the answer is D) mouthpieces for breathing. This is the only way they can stay underwater for long periods of time. If they came up every 10 seconds for breath, they would waste a lot of time.
I hope I helped you!
Social. -Interacting with your family. ...
Mental. -How we cope with problems. ...
Physical. -Having a balanced diet.
I think this a tough question, and I hesitated between a) and b), but I choose the second answer - Physical Therapist.
Physical Therapists are licensed providers of care, and their educational education has evolved to the point where physical therapists graduate with a doctorate in physcal therapy. Personal trainers have a degree or a certificate. This is not the same.
Answer:
The correct answer is <u>conducting a controlled experiment.</u>
I would have to say B. because yelling and screaming doesn't necessarily mean people will help you with the stress, it won't reduce the stress maybe for a short while, but that stress will still be there and it can still be as strong as before, it won't punish your heart or nervous system because physically stress is capable of that. screaming and yelling can make you feel better, but the stress will still be there. <span />
