The drawing below shows a cell inside a beaker. The solute contents of the cell and the beaker are noted in the drawing. Using the drawing:  1) Describe the solution in the beaker as hypotonic, hypertonic, or isotonic from the perspective of the solutes in the beaker. 2) Describe the direction of the water movement (into the cell, out of the cell, or equally in and out of the cell). 3) Describe what happens to the cell after the movement . isotonic.jpg

Red blood cells have a concentration of 0.9% NaCl. In which type of solution will crenation occur?

Intestinal cell ingest substances inside very small vesicles through a process called __________.

In a cell that produces important proteins, what would be the correct sequence of organelles from start (production of protein) to finish (secretion of protein)?

A data model is definitely in the 3NF if it does not have any functional dependencies.

Explain Tertullian’s logic for asserting the importance of materiality since the incarnation. How do Christ’s death and birth fit into his argument?

Create a ERD that captures the following data elements. Include tables, columns, datatypes, & keys in your ERD. Note: Just make decisions on the data types and lengths.  Use the data to develop your assumptions about the relationships.  There could be multiple accepted approaches so make sure you list your assumptions.    Create a normalized model with many entities. Draw this ERD on the given paper. If you don’t have a pen, just list it out in text format as given including the following: Table Name Columns & Datatypes PK: FK(s) and relationship if applicable: Assumptions: —————————————————— Example for how to format this: Table: Invoices Columns Invoice_ID – NUMBER(12) Vendor_ID – NUMBER(12) Invoice_Date – DATE Invoice_Number – VARCHAR(20) Invoice Amount – NUMBER(12) Payment_Amount – NUMBER(12) Invoice Due Date – DATE PK: Invoice_ID FK: Vendor_ID ties back to Vendor_ID on Vendors since Vendor to Invoices is a 1-m relationship 

Select all disadvantages of an unnormalized table as discussed in class: I – domain anomaly II – deletion anomaly III – update anomaly IV – truncate anomaly

Given three entities: Author, Book, and Book_Author. The cardinality on the author side of the relationship between Author and Book_Author will always be
