Honors Freshman Science

Subject : science
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.

23. Holds the cell in place and gives it structure






24. When the sister chomatids separate and the chromosomes move to opposite poles






25. When natural selection favors individuals of each species that avoid or reduce among coexisting species as a result of each species' niche differing from the others in one or more ways & reducing competition
