The vast amount of breakdown of his tooth enamel and the black discoloration, I suspect tartar and tooth decay may be the primary cause of this deterioration
<h3>Tartar</h3>
A dentist will have to remove the build-up when tartar is the cause, typically by scraping the tartar off the teeth. The dentist may have to use ultrasonic instruments that use vibration to break up the tartar and make it easier to remove.
<h3>Tooth decay</h3>
In cases of decay, it's unlikely that a dentist will be able to improve the black teeth through a simple cleaning. they're going to instead need to remove the decayed portion of the tooth.

Answer: True
Explanation:
The cardiovascular system includes the heart and blood vessels. The function of the heart is to pump out oxygenated blood via blood vessels to all the parts of the body. The blood vessels arteries, veins and capillaries contribute to the transfer and distribution of the blood.
The mechanism by which genes are transferred from a donor to a recipient microorganism is called TRANSDUCTION. After transduction, the genetic makeup of the recipient cell is different.
Transduction refers to the genetic recombination mechanism by which bacteria can transfer fragments of DNA by using bacteria-infecting viruses called bacteriophages.
During transduction, a bacterial cell interacts by a conjugal bridge through which fragments of DNA are transferred to a suitable (host) recipient cell.
This mechanism (transduction) changes the genome of the host cells by generating genetic recombinants when the bacteriophages initiate a new cycle of infection.
