Answer:

oxygen

Explanation:

Oxygen is the specific substance needed for muscle activity that is delivered to muscles most effectively as a result of increased heart rate.

The control of heart rate (HR) during rest and exercise is a good indicator of the level of intensity at which the heart is working and is an important information about a person's health status. The heart muscle will respond directly to the body's need for oxygen and blood flow at different times in life, both to perform an exercise of a certain level of intensity and during periods of illness or external need, in which the body responds by sending blood flow to the muscles and / or organs that require blood and O2 supply. Heart rate is an important part of different physiological variables. For example, cardiac output forms with the stroke volume. Heart rate is also part of the double product.

Which résumé is most likely to result in a candidate being hired?
Aloiza [94]

Treat your résumé with the respect it deserves. A single mistake or oversight can cost you interview opportunities.

- Give yourself plenty of time. Don't put off preparing your résumé until the last second

and then try to write it in one sitting.

- Learn from good models. You can find sample résumés online at college websites and on job boards.

- Don't get frustrated by the conflicting advice you'll read about résumés. Résumés are as much art as science, and there is more than one way to be successful with them. Choose the approach that makes the most sense to you and is compatible with what you know about business communication principles and practices.

I hope this helps:)
