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.

29. A lack of an essential hormone causes the disease and treatment involves replacing the missing hormone






30. Use of an organism's biochemical processes to produce a needed product - These processes have been greatly enhanced by use of recombinant DNA which allows organisms to be genetically modified to accomplish tasks that were previously not possible






31. Profile established by analysis of multiple markers provides unique characteristic of individual whose DNA is presented;






32. Actions of microbial enzymes that break down flour proteins ( gluten) and give dough its elasticity






33. Corn mash whiskey - is clear after distillation - the aging process while in an oak barrel for years - is responsible for the golden color and distinct taste of bourbon (or Jack Daniels Tennessee whiskey)
