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.

19. The mammalian oviduct that leads from the ovaries to the uterus






20. Describes organisms that are cooperative in action - such as hormones or other growth factors that reinforce each other's activity






21. The smallest particle that is capable of carrying out photosynthesis; the functional unit of a chloroplast






22. The central tissue of a stem - used for food storage






23. A portion of the CNS consisting of cytons (cell bodies) - their dendrites and synaptic connections






24. A chemical messenger that is secreted by one part of the body and carried by the blood to affect another part of the body - usually a muscle or gland
