Answer:
Porifera—gastrovascular cavity, coelomate.
Explanation:
Sponges do not contain digestive system but obtain nutrients through the diffusion process. Porifera is the most commonly asymmetrical in nature but can also have radial symmetry. Porifera has no coelom.
Lacking a true digestive system, they depend on the intracellular digestive processes of their choanocytes for their energy intake. Gas exchange, circulation, and excretion occur by diffusion between the water and the cells.
During the process of gene expression, the DNA to RNA step is known as transcription while the RNA to protein step is known as translation.
Gene expression is a process which involves the synthesis of a functional gene product by using the information present in the genes.
Transcription is a process which involves the synthesis of a RNA from the DNA. In eukaryotic cells, the transcription occurs in the nucleus whereas in prokaryotes the transcription occurs in the cytoplasm of the cell.
Translation is the process by which the RNA is converted into a protein. The translation in prokaryotic cells occurs in the cytosol of the cell whereas in eukaryotic cells, the translation occurs in the ribosomes.

Water, carbon, and nitrogen
Answer:
Explanation:Complementary base pairing is important in DNA as it allows the base pairs to be arranged in the most energetically favourable way; it is essential in forming the helical structure of DNA. It is also important in replication as it allows semiconservative replication.
