A scientist may use molecules - enzymes, proteins, DNA, RNA - to test for similarities, because if anatomy alone was used, it would be difficult to link traits and characteristics between the two organisms. For example, a rabbit has an endoskeleton and a closed circulatory system, while a fly has an exoskeleton and hemocoel.

During anaphase, homologous chromosomes separate and head towards opposite poles of the cell.
- A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase.
- After the metaphase procedure, the mitotic stage known as anaphase occurs during which the freshly replicated chromosomes are transferred to the opposing poles of the cell and the replicated chromosomes are split.
- Sister chromatids split from one another and are drawn to the opposite ends of the cell during anaphase.
- The sister chromatids are able to separate because the protein "glue" holding them together is degraded.
- Each chromosome now exists on its own. Each pair's chromosomes are drawn to the cell's opposite ends.

Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.

The erector spinae group of muscles includes the <em>spinalis </em>and the <em>iliocostalis, </em>and <em>longissimus</em> (Option 4).
<h3>What are erector spinae muscles?</h3>
The <em>erector spinae</em> muscles are a group of different muscles and mainly consist of 3 muscles. i.e., the <em>spinalis </em>muscle, <em>longissimus </em>muscle, and <em>iliocostalis </em>muscle.
<em>The </em><em>erector spinae</em> muscles is a muscle group located at the back, bilaterally along the spine.
The <em>erector spinae</em> serves to extend the back at the hip, thereby producing the torso being pushed upward.
