Biology
1 answer:
daser333 [38]3 years ago
7 0

Answer:

The correct answer is: Attachment.

Explanation:

  • Pilus are thread like structures which are present on the surface of the bacterial cell.
  • They are mainly responsible for attaching the bacterial cells to a substrate, for obtaining food or to an eukaryotic cell for the purpose of infection.
  • Pilus also mediate the process of conjugation in some bacterial cells.
  • Conjugation is a process by which genetic material or plasmids are transferred from one bacteria to another through a channel formed in between the two bacteria by the help of the pilus.
  • Pilus also helps the bacteria by preventing them from getting recognised by the immune cells in the host.
  • A defective pilus will affect all the above processes, resulting in death of the bacteria.

Where is over 95% of incoming ultraviolent radiation absorbed
zheka24 [161]

Answer:

Over 95% of incoming ultraviolet radiation is absorbed in :

A. The Stratosphere.

Explanation:

  • Stratosphere is the second layer of the earth's atmosphere that lies next to the troposphere.
  • This layer experiences very little turbulence of air and is very significant because of the presence of Ozone layer in it.
  • The UV rays entering the Earth's atmosphere, photo dissociates ozone into O₂ and O. But these molecules quickly recombine to form ozone.Thus, stabilizing the concentration of ozone in the atmosphere.
  • During this photo dissociation UV radiations loses much of its energy. Thus, 95% of incoming Ultraviolet radiation gets absorbed in the Stratosphere.
  • Absorption of ozone UV radiation increases exponentially with the thickness of ozone layer.
