Questions 5 through 9 relate to the following scenario. Suppose that you are asked to create an ER diagram for a real estate firm that lists properties for sale. The following rules describe the data requirements for this firm. The firm has a number of sales offices in several states. Attributes of a sales office include Office Number (identifier) and Location. Each sales office is assigned one or more employees. Attributes of employee include Employee ID (identifier) and Employee Name. An employee must be assigned to only one sales office. For each sales office, there is always one employee assigned to manage that office. An employee may manage only the sales office to which he or she is assigned. The firm lists properties for sale. Attributes of property include Property ID (identifier) and Location. Components of Location include City, State, and Zip Code. Each unit of property must be listed with one (and only one) of the sales offices. A sales office may have any number properties listed or may have no property listed. Each unit of property has one or more owners. Attributes of owners are Owner ID (identifier) and Owner Name. An owner owns one or more units of property. Attribute Percent Owned represents ownership percentage of a property by an owner. Assume that you drew the draft ER diagram for this real estate firm below.  However, this solution is neither complete nor fully correct. Please answer the questions related to this draft solution. Consider the Manages relationship between EMPLOYEE and SALES OFFICE entities. Which of the following cardinalities are missing in this relationship?

Questions 29 through 31 relate to the following ER diagram. After a few iterations, we developed the following partial relational schema in a graphical notation, which is neither complete nor fully correct. Please answer the questions to complete this partial schema. Which attribute, if any, is missing in the PROPERTY relation?

Questions 26 through 28 relate to the following ER model. How many relations are needed to build the relational schema for the ER diagram?

Show your workspace.  Your face, both hands, paper, calculator, and notecard should be visible on the video throughout the exam.  You may have to move the computer farther from you to accomplish this.  Items may not be moved in and out of the visible workspace. Showing workspace from Proctorio .png If something goes wrong, email your work and a description of what happened to pcormier@southplainscollege.edu immediately. Failure to follow these guidelines may result in a zero on the exam or being dropped from the course.  I reserve the right to ask you to work any problem on the exam that you answered correctly.

Submit your work to Gradescope Exam 2 within 10 minutes of submitting the exam on Blackboard.  Failure to do so will result in 50 – 100% deduction in your grade.  If anything goes wrong, email your work to me immediately.

Two curves showing the rate versus substrate concentration are shown below for an enzyme-catalyzed reaction. One curve is for the reaction in the presence of substance X. The other curve is for data in the absence of substance X. Examine the curves and tell which statement below is TRUE for the observation made.

In a certain enzyme-catalyzed reaction the following steps occur:1. A phosphate group on substrate A is transferred to a side chain of an active site residue of the enzyme.2. The dephosphorylated form of substrate A dissociates from the enzyme.3. Substrate B enters the active site and is phosphorylated with simultaneous regeneration of the enzyme in its original form.What kind of kinetic mechanism is described?

Carbohydrates are components of the following ________.
