  • 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. Are the organelles where cellular respiration occurs.

2. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.

3. Synthesis

4. Is found on the stem between nodes.

5. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).

6. Engages in both passive and active transport.

7. Digestive enzymes - hydrochloric acid - and gastric juices which aid in digestion. The mucous secreted by the stomach protects the stomach lining from the acids and juices.

8. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size

9. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.

10. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).

11. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).

12. Stood upright before there was an increase in brain size.

13. Some enzymes contain a __________ component that is essential to their functions.

14. Some energy is lost as heat and becomes unusable.

15. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.

16. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh

17. There was extensive radiation of fish during the Devonian and Silurian periods within the Paleozoic Era.

18. Is the outermost layer of cells of the stem.

19. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re

20. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.

21. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.

22. Contains many genes and is a structure comprised of linear DNA and associated proteins.

23. Are cells involved in immunity and are produced in bone marrow as stem cells.

24. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.

25. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.

26. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.

27. The total amount of genetic information available for a given species.

28. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.

29. Layer that will become the skin - some endocrine glands - and the nervous system.

30. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t

31. Develops from the morula as a thin layer of cells surrounding an internal cavity.

32. Allows for the genetic code to be preserved in future generations of cells.

33. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.

34. Includes all living and nonliving components of the Earth to support living things.

35. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.

36. Contains optic lobes - controls sight.

37. The phyla composed of segmented worms.

38. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t

39. The phyla of round worms.

40. The pituitary gland.

41. Inorganic phosphate

42. Transfers water and does not require sieve plates to allow nutrients through.

43. The individual we recognize as an adult fern.

44. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).

45. The transfer of electrons.

46. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).

47. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.

48. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.

49. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.

50. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.
