The correct answer is uracil.
<span>Uracil is one of the pyrimidine nucleotide bases which is the component of nucleic acid-RNA. In RNA, uracil binds to adenine via two hydrogen bonds (complementary binding). Uracil is not found in DNA, it is replaced by thymine because it is thymine’s demethylated form.</span>
False
<span>Marine ecosystems like lakes and oceans have aphotic zones. Aphotic zones refer to the zones in the water where there is little or no sunlight. It is found in bodies of water were depths only receive less than 1% of sunlight penetrations. Bioluminescence is essentially the only light found in this zone and most food comes from dead organisms that sink at the bottom of lakes or oceans. </span>
Answer:
Fluid lava (which is less viscous because it has less silica content) flows much further than viscous lava (that is high in silica content). Therefore, this types of lava forms shield volcanoes – low slopes and low height- because they flow over longer distances before they cool. Viscous lava from composite volcanoes that are high in height and have steep slopes.Explanation:
