(1) Maple trees are grown in 2 greenhouses where the only variable is temperature (15°C vs. 10°C). (2) The hypothesis is rejected. (3) There is no statistical difference in the number of leaves dropped at 10°C as compared to 15°C. (4) The observation is that maple trees drop their leaves in autumn. (5) The hypothesis is that maple trees drop their leaves because of colder temperatures.

Cоnsumptiоn оf dаrk chocolаte hаs been shown to have health benefits. A study was undertaken to see the effects of epicatechin (Epi), a substance in dark chocolate, on the aerobic capacity of leg muscles of mice. Aerobic capacity is how much respiration is taking place using oxygen. A group of adult mice was used to measure the effects of a low dose of Epi given over 15 days. The mice were divided into four groups and given either water or Epi and were either kept idle (no exercise) or made to exercise on a treadmill. After 15 days, the results were analyzed. The blood capillary density in leg muscle was measured under the light microscope. Capillaries are vessels which transport blood to the muscles. (a) Outline the trends in capillary density in the results of this experiment. [2] (b) Describe how increased capillary density could affect the aerobic capacity of muscle. [2] Leg muscle tension was measured over time during a treadmill exercise in all four groups. The muscle is considered to reach a point of fatigue when there is a decrease in tension to 50 % of the initial tension. (c) (i) State the time when the point of fatigue occurred in the Epi–exercise group. [1] (ii) Compare + contrast the results for the water–no exercise group and the Epi–no exercise group. [3] (d) Discuss the effect of exercise on the results of the experiment. [2] The scientists tested the expression of four different mitochondrial proteins. The protein samples were taken from leg muscles. The technique that was used to quantify the amount of protein expressed was Western blotting. In this procedure the thickness of the band is an indicator of the amount of protein. (e) Analyze the effect of exercise on the presence of the mitochondrial proteins in the leg muscle. [2] (f) The scientists concluded that Epi significantly increased aerobic capacity in leg muscle. Evaluate the strength of the evidence provided by all of the data for dark chocolate improving the aerobic capacity of athletes. [3] TOTAL 15 marks
