Question: The results below show the effects that fragmentation of forests has on trees. In Study A, the percentage of dead and dying trees of different sizes was estimated in the interior and at the edges of the forest fragments. The percentage increase of dead and dying trees at the edge was compared to that at the interior for trees of varying sizes. In Study B, the number of new tree seedlings was measured in a continuous forest and in forest fragments of areas 100, 10 and 1 hectare (1 hectare = 10,000 square meters). The results are shown below. Consider the following statements regarding the above study.
i. Conditions at the edge are more suitable for survival of trees.
ii. The wider trees have survived better in this study.

Question:Paramecium lives in pond water that is hypotonic to its cellular contents. However, paramedium does not burst due to excess water uptake because of its contractile vacuole.The vacuole collects fluids from a system of canals present in the cytoplasm. When full the vacuole and canals contract, expelling fluid from the paramedium.In an experiment, the activity of the contractile vacuole was monitored over time after placing paramedium in a growth medium with an osmotic concentration (osmolarity) of 4 mOsmol \( L^{-1} \) (similar to that of the pond water) for 30 minutes and then shifted to a growth medium having an osmolarity of 24 mOsmol \( L^{-1} \).Osmole refers to the number of moles of solutes that contribute to the osmotic pressure of a solution. Osmolarity is osmole per liter.Which of the following graphs is a correct representation of the activity of the contractile vacuole in these two media?

Question: Dr K is travelling in the Antarctic and collects a sample of unknown bacteria X that they want to characterise. They grow bacteria X on an agar plate containing horse blood and find that bacteria X can break down red blood cells (haemolysis). They then use a sterile needle to introduce bacteria X into a test tube of semisolid agar as shown in the figure to the left. Nonmotile bacteria are not able to move independently through semisolid agar away from the initial stab line, whereas motile bacteria are. Dr K finds that bacteria X can grow throughout the bottom of the test tube but never at the top, as shown in the blue test tube to the right. From the given information alone, what would the most reasonable conclusion be? Bacteria X are:
Choices:

Question: With the rise in drug-resistant bacteria, it is crucial that antibacterial drugs are effective and prescribed appropriately to prevent selecting for resistance in the bacteria. We also need to understand their effect on other bacteria cohabiting the human body to prevent development of resistant strains of these other bacteria. The Kirby-Bauer disk diffusion method is one technique used to assess the resistance of a bacterium to a drug. The bacteria are cultured on plates and small disks impregnated with specific antibiotics placed on the surface (coloured and labelled A-D below). The antibiotic from the disk diffuses into the growth medium as the bacteria on the surface of the plate replicates. Susceptible bacteria cannot grow in the presence of the antibiotic, resulting in a clear zone of inhibition around the disk. In contrast, resistant bacteria can replicate freely around the disk and there is no clear zone seen, just a ‘lawn’ of bacteria. The size of the inhibition zone is indicative of the effectiveness of the antibiotic impregnated in that disk. Zones of antibiotic diffusion should not overlap: if they do so a repeat of the experiment is required to determine their effectiveness. Which of the following statements is INCORRECT?
Choices:
A. Antibiotics B and C require a repeated experiment to determine their effectiveness
B. Antibiotic D is the best inhibitor of the growth of this bacterium
C. The incubation process caused the differential growth of this bacterium species
D. Antibiotic A is effective against this bacterium, although antibiotics B and C are potentially more effective than A
E. Antibiotic B has not diffused evenly from disk B

Question: Five different species of Australian animals were placed in laboratory chambers. The effect of changes in the temperature of the external environment (EM) on their metabolic rate was recorded and analysed. Each animal had similar body weights (around 50 grams) and the data was measured while the animals stayed at rest. Certain animals are able to reduce heat transfer better than others. An example of this is a thick layer of body fat which helps insulate fur seals in cold ocean waters. Which of the following species was best able to insulate temperature, based on the data presented above?

Question: In the human body, lung function is affected by physical activity. As the intensity of activity increases, the body has a higher demand for lung function. The lungs respond to this by increasing two parameters: tidal volume and ventilation rate. Tidal volume is the volume of air that is breathed in and out by the lungs at rest (i.e. without extra effort to have a maximum inhalation or exhalation). Ventilation rate is a measure of how many breaths a person takes per unit of time. Below is a graph showing data for an athlete on a treadmill. Which of the following statements is true?
Choices:
A. At a treadmill speed of 0km/hr, the tidal volume would approach 0 litres/breath.
B. If this experiment were completed on a young child instead of a fit athlete, both the tidal volume and ventilation rate would likely be significantly lower.
C. In an adult, a tidal volume of 0.15 litres and a ventilation rate of 40 breaths per minute would provide equally effective ventilation as a tidal volume of 0.6 litres and a ventilation rate of 10 breaths per minute.
D. If the treadmill speed continued to increase, the tidal volume would eventually reach a maximum value and would no longer increase any further.

Question: Bacterial count of a liquid culture can be determined by three different methods: 1. Cells can be counted under a microscope using a counting chamber; 2. The absorbance of the culture can be measured in a spectrophotometer (with A_600 = 1 corresponding to 8x108 bacterial cells/ml); 3. Several dilutions of the culture can be plated on agar and the colonies can be counted (see the figure below) to calculate the number of colony forming units per milliliter (cfu/ml). When repeating the plating of the most dilute solution, shown in the figure, many times:
Choices:
A. some plates will show colonies.
B. no growth will be observed on any plates.
C. some plates will show too many colonies to count.
