Answer:
B. Muscle
Explanation:
During embryonic development, three germ layers start to form in order to eventually go through the process of differentiation. These three layers are: the ectoderm - <em>outer layer</em> -, the <u>mesoderm</u> - <em>middle layer</em> -, and the endoderm - <em>inner layer</em> -.
The <u>mesoderm gives rise to the both skeletal and smooth muscles</u>, <u>blood vessels, heart muscle, cartilage and joints, bone, cartilage, joints, connective tissue, blood cells</u>, amongst other tissues.

I wanna say the answer is cause and effect
DNA polymerase is an enzyme which is needed for the synthesis of new DNA strand on the old DNA template. In order to synthesize new DNA strand, DNA polymerase requires many other enzymes or molecules such as:
1. All four deoxyribonucleotides triphosphates
2. Single stranded DNA template
3. Inorganic phosphate 3')H end of new DNA strand
During DNA replication, the double stranded DNA molecules mush unwind and form single stranded structures so the both the strands can be replicated simultaneously.
