Explanation:
Individuals are not born immediately able to play the piano. Therefore, piano playing is not an inherited trait. You get good because you practice.
This is in contrast to physical traits like hair color, ability to role your tongue, or genetic diseases. These are not learned at all, instead, they appear regardless of lifestyle.
However, some genes are thought to predispose you to musical talent. Two people could be born with exactly the same genes that make them good at piano. If one practiced for 8 hours every day, then they will be very good. If the other one never practiced, they wont be able to play.
In contrast, one person could have genes that make them great at piano, and one could have genes that make them terrible. Even if they practice the exact same amount, the one with the better-suited genes will likely progress more quickly!
However, the skill is still a learned trait.

To avoid contamination the tubes and dishes should not be kept open for a longer duration of time.
