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.

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






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






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