The answer is; A & C
The lagging strand is replicated in fragments called Okazaki fragments, each initiated by a primer. The fragments are later joined into one strand by DNA ligase. Replication occurs by adding nucleotides to the 3’ end of a preceding nucleotide. Because the lagging strand is antiparallel to the leading strand, the replication of the lagging strand is in the opposite direction as the replication fork direction. This is why the lagging strand is replicated in fragments because replication is being carried out by a single DNA polymerase (moving in the direction of the replication fork) per replication fork.
Answer:
The villi in the small intestine provide a large surface area with an extensive network of blood capillaries. This makes the villi well adapted to absorb the products of digestion by diffusion and active transport.

Answer: Monitor the site dressing and vital signs.
Explanation:
The bone marrow is the soft tissue inside bones that helps form blood cells. It is made up of a liquid part and a more solid part. And it is found in the hollow part of most bones. The bone marrow is
The biopsy and bone marrow aspiration are usually done at the same time. Together, these two procedures may be called a bone marrow study.
Marrow aspiration is the removal of a small amount of this tissue in liquid form for testing. Bone marrow biopsy and bone marrow aspiration are procedures that allow samples of bone marrow (the spongy tissue inside some of the longer bones) to be removed and tested. In a bone marrow biopsy, the doctor uses a needle to remove a sample of the solid part. In a bone marrow aspiration, a needle is used to remove a sample of the liquid part.
<u>Bone marrow aspiration and biopsy may indicate whether the bone marrow is healthy and producing normal amounts of blood cells</u>. Doctors use these procedures to diagnose and monitor blood and marrow diseases, such as some cancers and fevers of unknown origin. <u>After the procedure, it is important to control the wound so that it does not become infected, and to monitor vital signs.</u>
