10. A student performed a test to demonstrate that photosynthesis was dependent on sunlight. Which of
the following is true regarding their experiment?
(A) The left half the leaf was covered in aluminium foil to block sunlight for several days.
(B) The leaf was treated with starch after being removed from the plant.
(C) The cell walls of the leaf were degraded with an ice cold solution of ethanol.
(D) The blue-black colour in half of the leaf was the result of staining with iodine solution.
11. Which of the following is true regarding diagrams A and B, which represent the digestive systems of
two vertebrates?
A
B
(A) Vertebrate A is a herbivore and vertebrate B is a carnivore.
(B) As plant fibre is hard to digest, a herbivorous vertebrate has a longer and more complex digestive
tract than a carnivore.
(C) Vertebrate A could be a dingo and vertebrate B could be a koala.
(D) Both B & C are true.
12. Which of the following correctly states terms relating to a cell type, tissue, organ and an organ
system of a plant, in that order?
(A) Mesophyll, photosynthetic, leaf, vascular
(B) Epithelial, reproductive, meristematic, root
(C) Photosynthetic, phloem companion, vascular, mesophyll
(D) Reproductive, epithelial, root, mesophyll
13. A food technologist performed the following tests on a range of foods to determine the nutrients
present in the foods. Which of the following correctly states the positive test results for glucose or for
lignin?
(A) Glucose = pale blue solution turns reddish-purple.
(B) Glucose = pale blue solution turns orange-red.
(C) Lignin = stains orange-red.
(D) Lignin = stains blue-black.
14. Cells contain numerous organelles. Which of the following statements are correct relating to the
nucleus and ribosomes?
(A) The nucleus contains deoxyribonucleic acid (DNA).
(B) The DNA contains genes which code for a particular protein (polypeptide).
(C) Ribosomes are where proteins (polypeptides) are synthesised.
(D) All of the above.
15. Which of the following statements are correct regarding open and closed circulatory systems?
(A) An advantage of a closed circulatory system is that the circulatory fluid and the interstitial fluid are
separate, so each has particular properties (eg. the haemoglobin in red blood cells has high oxygen
carrying capacity).
(B) An advantage of an open circulatory system is that it requires less energy to push haemolymph around
the body.
(C) A disadvantage of an open circulatory system is that it cannot carry as much oxygen as blood can.
(D) All of the above.

20. To investigate the effect of surface area to volume ratio on rate of reaction some Preliminary Biology
students used two soluble aspirin tablets. They weighed them both at the beginning of the experiment and
found the two tablets had similar weights. One was ground to a powder using a mortar and pestle while
the other was left as a whole tablet. Both were added to 100ml water in 150ml beakers and the time for
the whole tablet and the ground aspirin to dissolve in the water was timed with a stopwatch.
(a) Explain why the tablets needed to be weighed at the beginning of the experiment.
