Answer:
An individual skeletal muscle may be made up of hundreds, or even thousands, of muscle fibers bundled together and wrapped in a connective tissue covering. Each muscle is surrounded by a connective tissue sheath called the epimysium. Fascia, connective tissue outside the epimysium, surrounds and separates the muscles.

Answer:
D. Prokaryotes only have one origin of replication to initiate replication.
Explanation:
The DNA of prokaryotes is smaller than that of eukaryotes. So, prokaryotes have only one origin of replication. Origin of replication is the region of DNA where the process of DNA replication starts. The helicases recognize and bind to the origin of replication to start the melting of DNA double helix for replication.
DNA replication starts at the single origin of replication and stops at termination in prokaryotes.
Earthworms maintain homeostasis by having a dual circulatory system, which contains the closed circulatory system and the coelomic fluid for respiratory gases, food and waste.
