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.
1. Spontaneous generation & life may arise from nonliving matter (incorrect idea)






2. Reproductive isolation due to different mating signals






3. A compound present on the outer surface of cells that aren't bacteria






4. All of the contents of the cell inside the membrane






5. The empty space in the ER tubes

7. The average per capita birth rate






8. Holds the ovaries to the body of the uterus






9. The constricted region in a chromatid






10. Produces testosterone






11. Where protein synthesis takes place






12. Growth response to physical disturbance & positive or negative






13. Going through protein channels with the concentration gradient






14. A compound on the surface of animal cells that allow cells to recognize and interact with one another






15. Camouflage






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






17. The divergence of two similar species living in the same geographic area






18. The probability of mortality is highest at a young age & the survival probability increases with age






19. The time inbetween meiosis 1 and 2






20. The net energy available for biomass production by consumer organisms






21. A parasite that lives inside the host






22. Behavior that is common to a population & learned from other members of the group & and transmitted from one generation to another






23. Where cell aerobic respiration takes place






24. When DNA replicates






25. Larger cells






26. A piece of DNA made on the lagging strand






27. Produces semen (2)






28. Reproductive successfulness






29. A species that is crucial in determining the nature of the entire community and that greatly affects the rest of the community & keeps the who ecosystem in balance






30. Each gene is present in two copies & when gametes are formed each gamete gets only one of the two factors






31. Turning energy from one form to another






32. When the cell prepares itself for division






33. Species that show repetitive reproductive cycles






34. A channel that takes things from one side of the phospholipid bilayer to the other by having a protein attach to the channel which changes its shape and moves the stuff to the other side
