Test your basic knowledge |

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.

2. Up or down






3. A mutation in which the entire reading chain is shifted & changed everything after an addition or delection






4. When a population is regulated by its environment's limits & grows until it levels out just below the carrying capacity and then oscillates

30. Regulates the ecosystem function by nutrient cycling and by availability of other resources






31. Aka contest competition & certain dominant individuals get a good supply of the limited resources while the other less dominant organisms in the population don't






32. An important part of the structure of ribosomes that has catalytic functions needed during protein synthesis
