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.

22. A structure in animal cells containing centrioles from which the spindle fibers develop






23. A transmitter substance released from the axons of nerve cells at the synapse






24. A constituent of the plasma of the blood of vertebrates; it is converted to thrombin by thrombokinase in the presence of calcium ions - thus contributing to the clotting of blood






25. An underground stem






26. Outgrowths of a root's epidermal cells that allow for greater surface area for absorption of nutrients and water

41. A type of virus that can destroy bacteria by infecting - parasitizing and eventually killing them






42. An enzyme from the pancreas that digests proteins in the small intestine






43. A complex carrier mechanism located on the inside of the inner mitochondrial membrane of the cell; releases energy and is used to form ATP

45. Small - disc-shaped bodies in the blood that play a chief role in coagulation






46. All the members of a given species inhabiting a certain locale






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






48. Degree of penetrability - as in membranes that allow given substances to pass through; the ability to penetrate






49. Structures in the testes that produce sperm and semen
