<span>A single stranded nucleic acid that plays a role in protein synthesis is known as the messenger RNA or mRNA (messenger Ribonucleic Acid). The other two types of nuclei acids are transfer RNA or tRNA and ribosomal rNA or rRNA. These nucleic acids are involved in cellular division in cells, during which transcription and translation occurs.</span>
Matter can be recycled, but energy cannot. Also, only 10% of the energy is passed through each trophic level.
The answer would be D.nucleus, prokaryotic cells don’t have a nucleus instead their dna floats around inside the cell
