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. The empty space in the ER tubes






2. A single cell made from the union of two gametes






3. A molecule consisting of a clycerol joined to three fatty acids






4. A fatty acid that doesn't contain the maximum possible number of hydrogens






5. 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






6. The information from the mRNA being used to form a protein






7. An arm of an amoeba






8. What something does and how it does it






9. The strand of DNA that is synthesized smoothly and continuously






10. The potential ecological niche of a species






11. Moving molecules into a cell






12. The accelerating population growth rate that occurs when optimal conditions allow a constant per capita growth rate






13. The number and types of species present & the relative abundance of each species & the interactions between different species & the resilience to disturbances & energy and nutrient flow & productivity






14. Aka chaparral & mixed scrub community with lower rainfall than in a deciduous forest






15. Holds the ovaries to the body of the uterus






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






17. A single strand of RNA that carries the information for making a protein






18. Male gamete released into the female






19. The strand of DNA that is always growing away from the replication fork & so only short pieces can be synthesized
