Answer:
Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.
Explanation:
Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.

The decibel (dB) is a dimensionless unit of magnitude used in telecommunications, electronics and acoustics.
Generally, the maximum advised dB for sound equipment is 90dB (you can see it in "safe" earphones). if you lessen to sounds higher than 90 dB for a long time, it could be hurtful for your ears.
