SAT Subject Test: Biology

Subjects : sat, science, biology
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.

18. A group of life-maintaining processes that includes nutrition - respiration (the production of usable energy) and the synthesis and degradation of biochemical substances






19. The creation of certain strains of specific traits through control of breeding






20. A process of formation of ova






21. The outermost embryonic germ layer that gives rise to the epidermis and the nervous system






22. In mitosis of higher plants - the structure that forms between the divided nuclei of the two daughter cells and eventually becomes the cell wall






23. Involuntary muscle






24. A fat-digesting hormone






25. The diffusion of water through a semipermeable membrane - from an area of greater concentration to an area of lesser concentration






26. An organism that produces spores; a phase in the diploid-haploid life cycle that alternates with a gametophyte phase






27. One of many tubules that absorb tissue fluid and return it to the bloodstream via the lymphatic system






28. The anaerobic respiration of carbohydrates






29. A structure found between the cerebral hemispheres of vertebrates; secretes melatonin






30. The hind portion of the forebrain of vertebrates






31. Requiring free oxygen from the atmosphere for normal activity and respiration

42. Laws of classical genetics established through Mendel's experiments with peas






43. A microscopic - whiplike filament that serves as a locomotor structure in flagellate cells






44. The thin - bent part of the renal tubule that is the site of the counter-current flow and the sodium gradient






45. A plant that lives on another plant mensalistically






46. A hydrogen carrier containing iron that functions in many cellular processes - including respiration






47. Protective immunity to a disease in which the individual produces antibodies as a result of previous exposure to the antigen






48. The study of the evolutionary descent and interrelations of groups of organisms
