Answer:
The correct answer is They both contain carbon ,but only nucleic acid contain phosphorous
Explanation:
Carbohydrates are also called polyhydroxyaldehydes or polyhydroxyketones.Carbohydrates contain carbon,hydrogen and oxygen.For example glucose(C6H12O6).
On the other hand nucleic are composed of nucleotides that contain nitrogen base,ribose sugar and phosphate group.
The presence of phosphate group in the nucleic acid make it different from carbohydrate.
The answer is Permian-Triassic extinction.
The Permian-Triassic extinction was 252 million years ago. It is known as The Great Dying because about 95% of all species died out due to environmental changes (volcanic eruptions, dry climate, melting of ice sheets, etc). This is also the only event in which many insect species wiped out.
There are sometimes similarities in the embryonic stages of organisms that do not exist in the adult stages.
