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.

45. Things that eat the producers & second lowest trophic level






46. A group of atoms that determines the types of chemical reactions and associations in which the compound participates






47. States that species richness is greatest at moderate levels of disturbance & so all the different species are at different stages in succession
