What happens to the speed of sound as it passes from gas to solid? Why?
Pani-rosa [81]

Question 3
shepuryov [24]

The statements Molecule B can be used to produce molecule A and Molecules B and C interact so that amino acids can be joined together are TRUE regarding the structures shown in the diagram (Options B and E).

<h3>What are transcription and translation?</h3>

Transcription is the process by which a DNA template (molecule B) can be used to synthesize a complementary RNA (molecule A), while translation is a process in which an sequence is used as templates to generate a protein, which requires tRNAs (molecule C) to trasnport amino acids to the ribosomes.

Therefore, with this data, we can see that DNA is molecule B used to create RNA, which is molecule A, while tRNA is represented by molecule C and it is used during translation.

yaroslaw [1]

Answer:

This structure has not been highly beneficial for the organism

Explanation:

Vestigial structures are cells, tissues, and/or organs that have no apparent function. Vestigial structures are retained during the course of the evolution, but often they are degenerate and/or atrophied (due to disuse). In general, these structures are homologous to anatomical structures that play a specific role in evolutionarily related species. Some examples of vestigial structures include, among others, the presence of the appendix in humans and wings in flightless birds.
