Answer:

D) epithelial tissue

Explanation:

The exchange surfaces of the organisms are the site for an exchange of substances or gases. These surfaces mostly lie within the body and protect the exchange tissues. The exchange surfaces of multicellular organisms are lined with epithelial tissues. These tissues have tightly packed cells with little or no intercellular spaces. The epithelial tissues serve to protect the exchange surfaces. Sometimes, these epithelial linings are modified to perform an additional function. The exchange surfaces are finely branched or folded to have a very large area. The digestive, respiratory, and excretory systems all have such exchange surfaces.

Answer:

DNA → mRNA → tRNA → Protein

DNA → mRNA → tRNA → Protein

Explanation:

This is because during protein synthesis, DNA is use to make RNA in the process called transcription. The DNA double strand is unwind by an enzyme called RNA polymerase to produce mRNA in the nucleus. The trans is produced in the nucleolus by RNA polymerase 1 and the site then binds aminoacyl tRNAs which is assembled in the RIBOSOMES. The tRNA are then translated into protein.
