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.

2. Cutting of vas deferens






3. Release of the egg






4. A symbiotic relationship in which one species benefits and the other is unharmed






5. Male gamete released into the female






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






7. The ability to produce viable offspring






8. The structure in the mitochondria






9. The study of how both the number of individuals in a certain species that are found in an area and the dynamics of the population






10. 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

18. Oscillation between two things that affect the population & keeps the population in check






19. Both dominant or recessive






20. When the cell prepares itself for division






21. The cells that don't become eggs in oogenesis

24. Produces semen (3)






25. Stable relationships that ensure cooperative behavior in mating and the rearing of the young






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






27. Found out that the hormone was being produced in the tip






28. When a population is regulated by its environment's limits & grows until it levels out just below the carrying capacity and then oscillates






29. When individuals of the same sex actively compete for mates






30. One species excludes another from its niche as a result of interspecific competition

48. The rate at which energy is captured during photosynthesis






49. The number of individuals of a species per unit of area or volume at a given time






50. Reproductive isolation due to structural differences
