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.
1. An organelle that regulates cell functions and contains the genetic material of the cell






2. Membranous organelles involved in the storage and modification of secretory products






3. The cellular layer that covers external and internal surfaces






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






5. The living together of two organisms in an intimate relationship






6. The place of attachment of the mitotic fiber to the chromosome






7. A mutation in which a single nucleotide base is substituted for another nucleotide base - or an extra nucleotide base is added






8. Plant growth stimulated by light (stem: + - towards light; root: - - away from light)






9. Genetic blending; each allele exerts some influence on the phenotype






10. The basal branch of each spinal nerve; carries motor neurons






11. Anaerobic respiration the yields 2 molecules of ATP - lactic acid - ethyl alcohol and carbon dioxide or some similar compound via the glycolytic pathway






12. An emulsifying agent secreted by the liver






13. Chemical groups attached to carbon skeletons that give compounds their functionality






14. The ourter part of the adrenal gland that secretes many hormones - including cortisone and aldosterone






15. The female gamete; it is nonmotile - large in comparison to male gametes - and stores nutrients






16. Pertaining to a type of gland that releases its secretion through a duct






17. A stalklike or elongated body part - usually pointed at one end






18. The contraction of the atria or ventricles of the heart






19. Occurs when a segment of genetic material on a chromosome becomes reversed






20. A membrane that envelopes the nucleus and separates it from the cytoplasm; present in eukaryotes






21. A process of cell division whereby each daughter cell receives only one set of chromosomes; the formation of gametes






22. The physical appearance or makeup of an individual - as opposed to its genetic makeup






23. An air duct from the middle ear to the throat that equalizes external and internal air pressure






24. In taxonomy - a classification between species and family






25. A chemical action that releases energy from glucose to form ATP






26. The first filial generation (first offspring)






27. Unicellular organism with simple cell structure






28. The reproductive organ that produces sex cells






29. Structures in the testes that produce sperm and semen






30. An endocrine gland of vertebrates - usually paired - and located near or within the thyroid that secretes parathormone - which controls the metabolism of calcium






31. An abbreviation of nicotinamide-adenine-dinucleotide-phosphate - also called TPN; an organic compound that serves as an oxidation-reduction molecule






32. A sensory hair structure in the utriculus and the sacculus of the inner ear; orients the head with respect to gravity






33. Any physical feature that prevents the ecological niches of different organisms from overlapping






34. A mature ovary






35. Technology that allows for manipulation of genetic material






36. The chamber in the alimentary canal of certain vertebrates located below the large intestine - into which the ureter and reproductive organs empty (as in frogs)






37. The description of a plant life cycle that consists of a diploid - asexual - sporophyte generation and a haploid - sexual - gametrophyte generation






38. A mass of cells that have similar structures and perform similar functions






39. A colloidal system involving the dispersion of a liquid within a liquid

47. A fat-digesting hormone






48. Daily cycles of behavior






49. The separation of some members of a population from the rest of their species; prevents interbreeding and may lead to the development of a new species
