Question

question 25 sociologists use which concept to refer to behavior that people expect from someone who holds a particular status? question 26 a can be considered a prop in the classroom performance of a professor. backpack lectern or podium cell phone confident tone of voice

Explanation:

In sociology, a role refers to the behavior expected from someone who holds a particular status. A role set involves multiple roles associated with a single status. A status set is all the statuses a person holds. Master status is the most prominent status a person has. Since the question asks for the concept of behavior expectations from a status - holder, the key term here is "Role".
For question 26, in the context of a classroom performance (like a professor's), a prop is an object used. A lectern or podium is an object (prop) used by a professor during a lecture. A backpack is a personal item, a cell phone is a communication device not typically a prop in a formal classroom performance, and a confident tone of voice is an aspect of communication (not an object/prop).

Answer:

Question 25: Role
Question 26: lectern or podium
