Answer:
Hair cells are present inside the inner ear that acts as a receptor of sound. Researchers affirmed that once there is a damage to the hair cell, it can regenerate in birds.
Damage hair cell can lead to loud noise which in turn affect the ear. The supporting cells are present along with the hair cells. When the hair cells get damaged, the supporting hair cell gets the signal to start the process of regeneration.
Answer - C
In water treatment and water purification plants, chemicals are added to destroy the bacteria when the bacteria have completed their task of digestion and are no longer useful for the process.
DNA replication follows the base pairing rule (A with T and G with C). This ensures identical replication of the genetic information; hence it's conservation. Each daughter DNA double helix contains one old strand of DNA and one newly-synthesized strand of DNA. This is known as the semi-conservative mechanism.
DNA replication also occurs during mitosis which produces haploid gametes. Each parent contributes half of the genetic information during fertilization of two gametes, thus regenerating the diploid number. Genes from both parents are transmitted to the offspring.
From what I have been taught at any point mutations can occur.
Your answer would be cumulus clouds.
