A feedback mechanism that increases respiration rate to exhale more co2 would be:_________
Arisa [49]

As your body needs more oxygen during exercising and produces more carbon dioxide, this might result in a high respiratory rate.

During exercise, your breathing may occur 3–4 times more frequently. Hyperpnea, or rapid, deep breathing, is the body's natural response to increased carbon dioxide generation. The pace of breathing increases along with the blood's concentration of carbon dioxide. The pH of the blood changes dramatically as carbon dioxide levels rise. The chemoreceptors in the medulla oblongata, a part of the hindbrain that controls respiration, detect this shift. To expel the additional carbon dioxide and breathe in more oxygen, the respiratory center speeds up breathing.

The temperature in a town started out at 55 degrees. By the end of the day the temperature dropped to -6 degrees.
garik1379 [7]

Answer:

The choice of the answer is fourth option that is -61 degrees.

Therefore the temperature drop is -61°Centigrade.

Explanation:

Given:

The temperature in a town started out at 55 degrees

Start temperature = 55°Centigrade. (Initial temperature)

End of the Day      = -6°Centigrade. (Final temperature)

To Find:

How far did the temperature drop?

Solution:

We will have,

\textrm{Temperature drop}=\textrm{Final temperature}-\textrm{Initial temperature}

Substituting the above values in it we get

\textrm{Temperature drop}=-6-55\\\\\therefore \textrm{Temperature drop}=-61\° centigrade

Therefore the temperature drop is -61°Centigrade.
