<span>One observation would be the physical size of Russia compared to other countries, despite a lack of visible borders from space. In addition, part of Russia's outline would likely be obscured by the various clouds and objects in the stratosphere; this would allow the astronaut to view potential cloud and weather patterns on earth. Also, an astronaut could see outlines of Russia's geography such as mountain ranges.</span>

Answer:
It is double stranded DNA, and it could be from an eukaryote, a prokaryote or a virus.
Explanation:
You can rule out the possibility of the nucleic acid being RNA because of the presence of thymine, which is absent in RNA, and is replaced by the base Uracil. In double stranded DNA, guanine pairs with cytosine, and thymine pairs with adenine, so the proportions of A and T, as well as those of C and G, should be the same. This is consistent with the information given, so you can conclude that it is indeed double stranded (this can also be concluded simply by the fact that it is DNA, because this type of nucleic acid is always double stranded).
All types of organisms can have a DNA genome, so it could either belong to eukaryotes, prokaryotes, or viruses. If it were RNA, it would only be possible for it to belong to a virus, since they are the only ones that can have an RNA genome.
Answer:
We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:
Reproduction - to make more of the same organism
Sensitivity - the ability to detect and react to stimuli
Nutrition - eat and digest food.
Movement - the ability to change its position or location
Respire - to breathe / gas exchange
Excretion - get rid of toxic / materials in excess
All living things show the characteristics above.
For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.
