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. All the alleles present in the population






2. Emphasizes species individuality & shows how each species has its own abiotic living requirements






3. AAAA...






4. The role of an organism within the structure and function of a community & takes into account all biotic and abiotic aspects of the species & as well as all the physical & chemical & and biological factors that it needs to survive & its habitat & wha






5. The enzyme that links the Okazaki fragments

7. Capillary bed that is adjacent to the capillaries of the uterine lining & exchanges everything except for blood






8. The production of gametes






9. When strands run in opposite directions






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






11. Forms the initial seed leaves (not actual leaves) & a side of the seed






12. A form of natural selection that increases inclusive fitness through the breeding success of close relatives






13. 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






14. Proposes that simple prokaryotic organisms began living in symbiotic relationships that eventually became obligatory (necessary) as one cell engulfed the other
