Answer:

C. Sound waves echo off the smooth walls of a large auditorium.

Explanation:

Echo provides an evidence out of many that matter can reflect waves.

Echo is produced when sound waves bounds off the surface of a resistant  body that does not allow it to transmit.

Reflection occurs when waves changes direction when they come in contact with another body. Auditoriums are made sound proof to curtail the effect of sound waves echoing.

It is a clear proof that matter can reflect waves.

Mariana [72]

Answer:

The one of best example would be appendix in humans.

Explanation:

In the past, the appendix may have helped in the digestion of the plants by producing mucus and prevent any type of infection. Plants with a high content of cellulose are digested with the help of the appendix as reported.

It is not a part of the human digestive system and considers as a vestigial organ. Vestigial organs are the organs that are present in an organism with no particular function and their removal will not lead to any harm. Humans do not need it because our digestive system is more efficient and works better in the first stages of digestion than they used to.

Thus, the correct answer is - appendix in humans.

DerKrebs [107]
<span>Depending on the situation, oxygen will be given and the patient will be instructed to breathe very slowly. If it is a panic attack, medication or a shot may be given to slow breathing and stop the attack. You can prop the patient up so they more easily breathe. Then they will administer oxygen and instruct you to take deep slow breaths. If this is caused by anxiety, further medication may be given. You might be clostrophobic or there might be a lot of dust in the house which would block the moisture in your lungs. This would make you gasp for air. You have a preliminary period of just classroom study before they let you loose on patients. This varies, but 6 wks at a minimum . Don't mean to alarm you but this could be lung leakage or a heart attack symptom. Or you could be suffering from anxiety.</span>
