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. Engages in both passive and active transport.






20. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






21. Contains optic lobes - controls sight.






22. The number of organisms in a given community - can be above or below the carrying capacity.






23. The sharp boundary of an ecosystem.






24. Carbon - Hydrogen - Oxygen - and Nitrogen






25. Is the sugar that lactase acts upon.






26. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






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






28. Studied the relationships between traits expressed in parents and offspring and the genes that caused the traits to be expressed.






29. 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






30. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






31. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






32. Absorb a photon of light and is found in the grana of the chloroplast.






33. Breaking down






34. What phylum are snakes in?






35. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.






36. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).






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






38. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






39. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






40. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.

44. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






45. Controls hunger and thirst






46. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






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






48. Subsets below the kingdom level






49. Refers to the birthrate of a population.






50. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.
