Answer:
A. Adenosine triphosphate
Explanation:
Molecule "a" shows the structure of ATP which stands for Adenosine triphosphate. ATP provides the energy that cells need to conduct the different processes within it.
Adenosine is made up adenine and ribose, which is attached to 3 phosphate groups, which you see there as the three circles with a P in it. These phosphate groups hold oxygen in them and they hold a lot of potential energy because of their negative charges.
<em>NOTE: If you take out one of these phosphate groups, you'll get the structure of molecule 'b'. So instead of "tri" which means three, you'll have a diphosphate because 2 will be left. </em>
Attached you'll see a labeled ATP molecule.
Answer:
Two countries that do not border each other: Norway and Iceland.
Norway and Iceland are separated by hundreds of miles of open sea, however, the two countries are very similar, both in culture, language and geography.
Both countries have fjords, both countries are cold during most of the year, and both countries speak North Germanic languages that descend from Old Norse (the language of the Vikings). This is because Iceland was first settled by people from Norway and from the British Isles.
Two countries that do border each other: Slovakia and Hungary
Slovakia is mountainous because it is crossed by the Carpathian Mountains. Hungary is flat.
In Slovakia, the dominant language: Slovak, is a Slavic language closely related to Polish and Czech.
Hungarian, the national language of Hungary, is a Finno-Ugric language that is more or less related to Finnish (but the relation is not that close).
