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.
Answer:
Reversibility means that an athlete can lose the effects of training when they stop, and can gain the effects when they begin to train again.
Detraining occurs within a relatively short time period after an athlete ceases to train. Performance reductions may occur in as little as two weeks or sooner.
In trained athletes, research indicates that detraining may result in greater losses in muscular power than strength. Strength losses are due to first to neural mechanisms, and next due to atrophy of muscles.
What is interesting is that strength levels after detraining are rarely lower than pre training levels, so training has a residual effect even when it is discontinued. But when the athlete returns to training, the rate of strength acquisition is high.

Health experts recommend that to be considered active, a person accumulate the equivalent of 1½ to 2 miles of walking per day.
If you walk at a brisk pace for 30 minutes, you'll cover a distance of about 1½ to 2 miles (2.5 to 3.3 kilometers).
The national academy of science is one of the prestigious institute of the science for the students. This institute is present in United states and is a private organization.
The physical activity is important for the individual health and reduces the chance of diseases. The daily 30 minutes(1½ to 2 miles of walking per day) of the physical activity is important for all the individuals and this has been recommended by the institute of science as well.
