Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The formation of rust due to corrosion in the body is due to the reaction between these 3 things ____ - ____ - and ____ .






2. ______ Molecular weight degrades slower than lower MW






3. You're working on a square polymeric implant of 5cm length and 2mm thick. You've been asked to suggest a precise way to fabricate it - what would you suggest?






4. Rather than randomly moving - moves in a directed cell migration manner for specific functions.






5. ____ is a measurement that characterizes the breadth of the distribution of a polymer's molecular weight.






6. Classify the following polymers into appropriate families based on their bond structure i.e. the polymer is an example of poly ____.






7. This cleaves into fibrinogen which creates fibrin (a sticky enzyme that allows blood to clot)
