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.

15. Reproductive isolation due to molecular and chemical differences






16. A periodic long-distance travel from one location to another






17. The person that said that the human population would quickly outgrow the natural resources and that it would cause war






18. Warning coloration & conspicuous colors of patters which advertise a species' unpalatibility to potential predators






19. Stores water in plants






20. The movement of alleles






21. When natural selection favors individuals of each species that avoid or reduce among coexisting species as a result of each species' niche differing from the others in one or more ways & reducing competition






22. Top of the stamen & where pollen is produced






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






24. Triggers mitosis when it binds with cyclins at high enough concentrations & survives mitosis

35. Sex cell






36. The process by which heritable traits make it more likely that an organism will have greater reproductive success






37. 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
