Expert Solution

Difference between groups of archae.Extreme halophiles are archae that prefer environment with high salt level and hence known as salt loving.Extreme thermophiles are archea that prefer very hot enviroment such as hot springs,volcanoes,geysers etc.Methanogens are archae  some that prefer environment such as swamps or in guts of cows.

Compare and Contrast viruses with cells:

Compare:

  • Both virus and cells have genetic material.
  • Both virus and cell possess the ability that they can evolve.

Contrast:

  • Viruses are non living while the cells are living.
  • Virueses are smaller in comparision to cells.
  • Viruses always requires a living host to survive and reproduce while cells can exist alone as an enity by themselves i.e like bacteria, part of a larger organism, like the cells of our body.
  • Viruses do not possess cell organelles while cells possess cytoplasm and cell membrane and some like eukaryotic cell possess all cell organelles.
  • Genetic material in virus is either DNA/RNA while in cells it is DNA.
  • Virus reproduce only inside host while cells reproduce via mitosis or binary fission alone.
