Final answer:
An MLA heading includes the student's name, instructor's name, course title, and date of submission, aligned left and double-spaced on the top of the first page.
Step-by-step explanation:
The elements present in an MLA heading for a student's paper include the student's full name, the professor's name, the course title, and the date of submission. In terms of formatting, it typically appears at the top of the first page and does not require a separate title page. The heading is double-spaced and aligned to the left margin. Following the heading, the title of the paper is provided, which is centered on the page and not boldfaced.
