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.

15. The two types of white blood cells:






16. The trigger for activation of enzymes (anything but endothelial cells!)






17. Process of producing new blood vessels due to a lack on oxygen and thus inducing VEGF.

22. What types of wound healing results from injury with inflammation?






23. Two things needed in the end product of the creation of a scab






24. Type of fiber drawing that controls details of a polymer by etching on a microscopic level; thus - controlling mechanical properties as well

27. Thrombin activates several upstream factors.






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






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






30. Resulting from the build up of too much collagen at the surface of injury during the granulation tissue stage of proliferation
