Earth is unique in the solar system because it has a relatively stable and mild (blank)
Alexandra [31]

Several conditions make our planet earth unique, to answer this statement we need to understand that.....

<h3>Earth is unique</h3>

There are many planets in the solar system, however, none have a location like planet Earth. Our planet is in a privileged condition, as it is located at a distance from the sun that does not prevent the emergence of elements essential for sustaining life, that is to say, it is not very close, a fact that would raise temperatures, and very far away, when they would be very low, hindering the development of lives.  This factor was decisive for the formation of liquid water on planet Earth, since it is the only one with such a resource in the solar system.

With this information we can come to the conclusion that the statement is <u>correct,</u> the stability of the earth and location in the solar system, provided that the earth could have water in a liquid state.

How are viruses different from bacteria? APEX
andreyandreev [35.5K]

Bacteria are unicellular microorganisms that can be found everywhere in the environment. Viruses are microorganisms that can only reproduce within the cells of a host organism.

The differences between viruses and bacteria include;  

  1. Viruses do not have any cell and are considered between living and non-living things, while bacteria have one cell (Unicellular) and are living organisms.
  2. Viruses are smaller in size (20-400 nm) when compared with bacteria (1000 nm).
  3. Viruses do not have a cell wall but a protein coat is present, while bacteria have a cell wall that is composed of peptidoglycan.
  4. Viruses require a living cell to reproduce, while bacteria can reproduce by itself.
  5. The DNA or RNA of viruses is enclosed inside a coat of protein, while that of bacteria floats freely in the cytoplasm within the cell.
