Amphibians are referred to as the "planet's greatest survivors" because they have repeatedly avoided extinction over the course of 400 million years.
<h3>How did the amphibians survive?</h3>
Over the years, the amphibians have had to adapt to various surroundings. Small animals called amphibians require water or a moist environment to exist. This group of species includes newts, salamanders, toads, and frogs. All have extremely thin skin that allows them to breathe and absorb water. Additionally, amphibians have unique skin glands that create functional proteins.
According to fossil evidence, amphibians descended from lobe-finned lungfish about 365 million years ago. They were very successful since they were the first terrestrial vertebrates. Some of them were considerably bigger than modern-day amphibians. The predominant group of land vertebrates for more than 100 million years was amphibians.

Answer:
Read Below
Explanation:
Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected
This is true because eukaryotic cells are the organism cell. TRUE
