Answer:
Explanation:
The human ear can easily detect frequencies between 20 Hz and 20 kHz. Hence, sound waves with frequency ranging from 20 Hz to 20 kHz is known are audible sound. The human ear is sensitive to every minute pressure difference in the air if they are in the audible frequency range.

The number of children born to an average woman in a population during her entire reproductive life is called total fertility rate (TFR).
The total fertility rate (TFR) is the total number of children likely to be born to a woman in the population if she were subject to the childbearing years giving birth to children according to an existing schedule of age-specific fertility rate. The total fertility rate is obtained by adding the single-year age-specific rates at a specific time.
Answer:
The correct answer is: c) the heart rate slowed and eventually stopped.
Explanation:
The vagus nerve (X) is a cranial nerve with the function to parasympathetically <u>innervate the heart, the lungs and the digestive tract. </u>
As a part of the Autonomic Nervous System (ANS), the vagus nerve regulates things such as heart rate and gastrointestinal peristalsis (things we cannot control).
Given that it is a component of the parasympathetic division of the ANS, it stimulates the organs when the individual is performing normal activities like <u>resting and feeding</u> (unlike the sympathetic division, responsible for the fight-or-flight response). For this specific reason, the vagus nerve slows the heart rate, so if it were to be stimulated in a frog, it would produce the same thing and ultimately lead to its heart stopping.
