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. The largest form of invertebrates that have jointed parts - like claws - legs - and antennae - bilateral symmetry - and segmented bodies






2. The top layer of skin and made up of five layers






3. Animals that do not have a backbone - like butterflies - sand dollars - and starfish






4. Neurons that transmit signals between sensory and motor neurons






5. Two organs in the lower back which the blood travels to get cleansed of urea






6. Plant - like organisms that don't have roots - stems or leaves - but they have chlrophyll which allows them to do photosynthesis






7. The shape that DNA is formed within






8. Photoreceptive nerve cells that are sensitive to light and can be triggered by a single photon






9. Algae that has chlorophyll - but also has a red pigment which helps them absorb sunlight from deep underwater






10. The condition - if not treated - when the inflamed appendix breaks and releases bacteria to the body. It can cause organ failure and death






11. Human body system that protects insides including skin - hair - and nails






12. Porrtion of the spinal chord that reflects impulses to and from the brain






13. The command center of the cell and is guided by the DNA contained within






14. Plants that only live for a few seasons and reproduce only once - including flower box flowers and crop plants






15. Warm - blooded and maintains a constant body temperature






16. The fluid filled gap that axons are connected to in the neuron






17. Glands in women and men that produce the sex cells for reproduction






18. The process that plants use to reproduce. Insects travel from plant to plant dropping off pollen into the pistills






19. Fibers of the dermis that gives the skin its structure - elasticity - and strength






20. Vibrations in the air around you






21. Holes caused by plaque buildup that expose the sensitive portion of the tooth






22. The far - back molars that take forever to come out






23. Extensions on a neuron that stretch out of its body and transmit messages throughout the nervous system






24. The inabiliy to hear sound






25. The soft inner layer of a tooth that supports the enamel and gives the tooth its shape






26. Organ beneath the papillae of a tongue that enables one to taste things






27. Cell organelle that stores water - waste products and food until needed






28. The tough - elastic skin of a sponge






29. The male sex cells of a flower






30. The way that hormone production is regulated by the cells producing chemicals that stop certain hormones from being released






31. Metabolic reactions that break down complicated models from food into simpler molecules






32. Soft - bodied invertebrates that have a protective shell and muscular foot that allows them to move around and anchor themselves






33. Joint that is used by shoulders and arms. One bone ends in a ball shape that fits into the socket of the other bone






34. Gland that secretes the hormone melatonin - which is important for the sleep cycle - metabolism - and sexual development






35. Area surrounding spinal chord that has motorneurons responsible for voluntary movement and flexibility






36. Something that has lost almost all of its use through evolution






37. Dome shaped muscle that the lungs rest on






38. The tiny threads that fungi attach to their food with






39. Undeveloped plants with stored food in a protective covering






40. Tough muscle tissue that connect bones to muscle






41. Also known as leukocytes - cells found in blood that prevent one from getting sick






42. Cells found inside leaves that are important for photosynthesis and contain chloroplasts






43. The stems at the edge of the flower that contain the male sex cells called pollen






44. A neuron cell's body






45. A shield that protects pathogens from entering the body






46. Multi - celled organisms that eat food to survive






47. Prokaryotic cells that are the oldest forms of life on Earth and survive in extreme conditions like hot springs - salt lakes - and underwater trenches






48. Substance found in the center of the spinal chord that provides nourishment to spinal chord cells and serves as a shock absorber






49. A meaty flavor sensed by the taste buds






50. The part of an arachnid that the mouth - eyes - and limbs are connected to
