Answer:
Phosphate sugar backbone:
The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
Nitrogenous base:
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine.
Purines on the other hand make 5-sided and 6-sided rings. Examples of purines are Guanine and Adenine.
The nitrogen bases are helped together through hydrogen bonds.
Hydrogen Bonds:
A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

It would depend.
The weather might be different form mine. I can give you the four main types of clouds there are to help you identify them.
Cirrus clouds are wispy, feather like clouds. They are higher than the other types of clouds.
Stratus clouds are low level clouds that are light gray. They might cause fog.
Cumulus clouds are puffy, white clouds.
Cumulonimbus could are very tall clouds that produce T-Storms. They are a very dark gray.
There are other types of clouds, but these were the four I learned.
Answer:
Having bacteria would produce organic molecules and defeat the whole purpose of the experiment which is to make organic molecules from inorganic molecules. The experiment was supposed to demonstrate the formation of the first organic molecules that initiated life on primordial earth. It is believed that lightning powered the formation of the first simple amino acids, like glycine, from the primordial atmosphere which was mainly composed of carbon dioxide and methane.
Because they can make energy, is free to anybody, and can be found everywhere that you go.
The first one with the boxing crab and anemone is mutualism.
The second one with the dog and flea is parasitism.
