Answer:
C. Acquired herniations of the muscular colon wall mucosa and submucosa
Explanation:
Hernia refers to the development of outgrowth or protrusion of all or part of the organs through their cavity walls or membrane. Diverticulosis is herniation of mucosa and submucosa of the wall of the colon. Diverticulosis is one of the conditions caused by the imbalance of homeostasis. Many sac-like outgrowths develop in the wall of the colon. The outgrowths are in the form of pouches and are called diverticula.
The out-pouching occurs where the muscularis layer of the wall of the colon has weakened. The people with diverticulosis may have no symptoms and no complications. However, when diverticulosis causes inflammation, the person experiences several complications such as pain, vomiting, nausea, etc.

Answer:
B
Explanation:
DNA replication is semiconservative- meaning the old template strand will form a double helix with the newly synthesized strand. The DNA polymerase can only replicate DNA in the 5’ -> 3’ direction on a DNA strand. However, because the two strands of a DNA double helix run antiparallel (and they are replicated together), then during replication, one strand will be oriented in the opposite direction (i.e 3’ -> 5’ direction).
Because DNA polymerase requires a primer to begin replication, the leading strand will require one primer, because replication on this strand occurs continuously. On the lagging strand, many primers are required because replication is done piecemeal forming fragments called Okazaki fragments. The fragments are later joined by DNA ligases.
