CPR is an emergency method of heart pumping in case of attacks and includes artificial ventilation. 100 compressions should be performed every minute.
<h3>What is CPR?</h3>
CPR is a cardiopulmonary resuscitation method of an emergency first aid tool used as a life-saving technique in case of heart attacks and drowning.
CPR is given to a person when the heart rate is very less and the pulse rate is very faint. The rate of the compression varies for age groups and should be given with a perfect rhythm and sync.
Cardiopulmonary resuscitation should be given as 30 compressions and then artificial breath or ventilation in between followed by another 30 compressions.
Therefore, option C. 100 compression in 1 minute is correct.

Answer: CPR
Explanation: It is the function that maintain's the brain until it starts beating on it's own.
Answer:
The correct order of events in sound transmission is 1, 4, 2,3 5
Explanation:
1. Tympanic membrane vibrates.
4. Ossicles of the ear vibrate.
2. Internal ear fluids are set in motion.
3. Hearing receptors are stimulated.
5. Auditory cortex is stimulated.
Sound is received by external ear or pinna that travels into the ear canal and causes the eardrum or tympanic membrane to move. The tympanic membrane vibrates with sound waves. Sound vibrations move through the ear bones or ossicles to the cochlea and cochlea moves due to sound vibration. Fluid movement causes the hair cells to move. As hair cells move up and down, electrical signals is generated. The auditory nerve sends electrical signal to the brain, which turns it into a sound.
