Older generations had more accurate health information, and people were more active.
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.

Although peer pressure can influence adolescents’ alcohol use, individual susceptibility to these pressures varies across individuals. The dopamine receptor D4 gene (DRD4<span>) is a potential candidate gene that may influence adolescents’ susceptibility to their peer environment due to the role dopamine plays in reward sensation during social interaction. We hypothesized that </span>DRD4<span> genotype status would moderate the impact of 7th-grade antisocial peer pressure on 12th-grade lifetime alcohol use (</span>n<span> = 414; 58.7 % female; 92.8 % White). The results revealed significant main effects for antisocial peer pressure, but no main effects for</span>DRD4<span> genotype on lifetime alcohol use. Adolescent </span>DRD4<span> genotype moderated the association between peer pressure and lifetime alcohol use. For individuals who carried at least one copy of the </span>DRD4<span> 7-repeat allele (7+), antisocial peer pressure was associated with increased lifetime alcohol use. These findings indicate that genetic sensitivity to peer pressure confers increased alcohol use in late adolescence.</span>
