A clade is a group of species that includes an ancestral species and all of its descendents
The answer is B
Before the process of translation occurs, mRNA which bears the blue print or coded information for the synthesis of a specific protein arrives from the nucleus and into the cytoplasm where there are ribosomes
mRNA then attaches itself to a ribosome. The ribosome is the site where the protein is formed. It is sometimes referred to as the "work bench" of the cell. Once mRNA is attached, tRNA comes and begins to read and translate the coded information on the mRNA. This is the translation stage of protein synthesis.
Based on the translated information, tRNA then fetches amino acids from the pool of free amino acids found in the cytoplasm and brings them to the ribosome where they are joined to form a chain thus creating a protein.

Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. They all have the same basic pattern of bones. They inherited this pattern from a common ancestor. However, their forelimbs now have different functions
