Montano1993 [528]

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

<h3>What are prokaryotic cells?</h3>

Prokaryotes are organisms whose cell (or cells) are characterized by the absence of a nucleus or any other membrane-bound organelles.

Prokaryotic cells are opposed to their eukaryotic counterparts that possess a membrane-bound nucleus that houses their genetic material (DNA).

Examples of prokaryotes are as follows:

  • Bacteria
  • Archeaebacteria

Therefore, cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

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.
