Step-by-step explanation:
The student has asked a question regarding a term related to human anatomy. Specifically, they are asking to fill in the blank in the statement: "A col is a surgery that removes or excises a portion of the colon " The correct answer is 'a. colon'. A col refers to a surgical procedure known as a colectomy, which is the removal or excision of a portion of the colon. Furthermore, regarding the question about which part of the large intestine attaches to the appendix, the answer is a. cecum'. The cecum is the initial part of the large intestine and is the segment to which the appendix is attached. The colon is the largest portion of the large intestine, which includes the ascending colon, transverse colon, and descending colon. To avoid confusion, it's also worth noting that the corpus callosum is unrelated to the colon; it is a nerve bundle that connects the two cerebral hemispheres of the brain.
