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.

22. Holds the cell in place and gives it structure






23. Microsporocyte after meiosis






24. Focuses on the evolution of social behavior through natural selection






25. Lays eggs

27. Coccus prokaryotic cells






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

37. An evolutionary modification that improves the chances of survival and reproductive success in a given environment






38. Turning energy from one form to another






39. Cells don't produce new cytoplasm to make the cell bigger & they produce an excess of protons which soften the cell walls so that the water vacuole fills up and makes the cell bigger






40. Compounds with the same molecular formulas but different structures






41. The contribution that each parent makes in producing and rearing offspring
