Answer:
transformation is carried out by random uptake of DNA, and transduction by a bacterial virus
Explanation:
Transformation and transduction are two of the three processes bacteria uses in genetic recombination (the third being conjugation). As rightly stated in the question, both processes establish that DNA is the genetic material of most living organisms and they both involve transfer and expression of DNA from cell to cell.
However, both processes are different in the way they get the foreign DNA into the bacteria cell.
- Transformation involves the random uptake of foreign extracellular DNA by the host bacterial cell.
- Transduction involves the transfer of foreign DNA into a bacteria cell via a virus called BACTERIOPHAGE. N.B: A bacteriophage is a virus that infects a bacteria host.

<span>The tympanic membrane or eardrum is a membrane in the ear that vibrates when hit by sound waves.It is tightly stretched and separates the ear canal from the middle ear. When sound waves hit the tympanic membrane, it vibrates. these vibrations are then passed to the middle ear, which consist of the ossicles or ear bones. </span>
