9700/11/M/J/10 22 DNA is said to replicate in a semi-conservative way. Results of Meselson and Stahl’s experiments gave overwhelming support to this theory. They used E. coli which has a generation time of 50 minutes. Here are the steps in their experiment but they are in the wrong order. P All bacteria contain 15 N DNA. Q All bacteria contain hybrid DNA (15 N DNA and 14 N DNA). R Bacteria contain either all 14 N DNA or hybrid DNA. S Bacteria grown in a 15 N medium for many generations. T Bacteria transferred to a 14 N medium and sampled every 50 minutes. Which sequence of letters shows the correct order of the steps in the experiment?

P Q R S T Which letters identify the flow of current through the atria and the recovery of the ventricle walls? A P and R B P and T C Q and R D Q and S 29 What is systolic blood pressure? A the blood pressure in the arteries when the heart is relaxing B the blood pressure in the left ventricle at the end of a contraction C the maximum blood pressure in the arteries D the maximum blood pressure in the right ventricle 30 Aortic stenosis is a heart valve disorder in which the aortic semi-lunar valve opening is narrow. Which effect could aortic stenosis have on the heart structure and function? A The tendons of the heart valves are weakened by blood being forced back through the bicuspid/left atrio-ventricular valve into the left atrium. B The cardiac muscle of the left ventricle wall is thinned by blood leaking out of the left ventricle during ventricular diastole. C There is less cardiac muscle in the left ventricle and reduced diastolic blood pressure, caused by the smaller blood volume entering the left atrium. D The wall of the left ventricle thickens, leading to an enlarged heart and inability to relax and fill completely during diastole.

9700/11/M/J/10 33 The diagram shows a spirometer trace with tidal volume and vital capacity. tidal volume volume /dm3 vital capacity X Y 6 5 4 3 2 1 0 time What happens to the volumes labelled X and Y during moderate exercise? volume X volume Y A decreases decreases B decreases increases C increases decreases D increases increases 34 What are the causative agents of cholera, malaria and TB? cholera malaria TB A bacterium insect virus B bacterium protoctist bacterium C virus insect virus D virus protoctist bacterium 35 40 % of the world’s population live in an area where malaria is a threat to health. In recent years there have been many more cases in Africa. What is the social factor that is letting the spread of malaria get out of control? A an increase in drug resistant forms of malaria B climate change C difficulty in producing a vaccine D migration of people because of wars

9700/11/M/J/10 [Turn over 36 What is a difference between T-lymphocytes and B-lymphocytes in the immune system? T-lymphocytes B-lymphocytes A do not form plasma cells form plasma cells which secrete antibodies into the blood stream B do not stimulate macrophages to carry out phagocytosis stimulate macrophages to carry out phagocytosis C formed from cells in the thymus formed from bone marrow cells D produce memory cells do not produce memory cells 37 In an investigation into the immune response, a volunteer was exposed to two different antigens, X and Y. The relative antibody concentration in the blood was measured at regular intervals over 60 days. The graph shows the time when the volunteer was exposed to each antigen and the antibody concentration against time for antigens X and Y. 0 5 10 15 20 25 30 35 40 45 50 55 60 first exposure to antigen X second exposure to antigen X first exposure to antigen Y time/days antibody concentration /arbitrary units antibody for antigen X antibody for antigen Y What is the explanation for the results displayed on the graph? A A primary and secondary immune response against antigen X occurred, with the memory B-lymphocytes inhibiting the secondary immune response against antigen Y. B A primary immune response to antigen Y occurred and memory B-lymphocytes specific to antigen Y enhanced the secondary immune response to antigen X. C Memory B-lymphocytes specific to antigen X enabled a secondary immune response to occur; different B-lymphocytes were activated for a primary immune response for antigen Y. D Plasma cells remaining from the first exposure to antigen X undergo rapid clonal selection to produce high levels of antibody against antigen X and lower levels of antibody against antigen Y.

9700/11/M/J/10 40 Two species of animal are found in the same area of forest and grassland. In the spring and summer they eat the same plant food. However, in the autumn and winter one eats nuts in the forest and the other eats roots on the grassland. Both species are preyed upon by the same predator. Numbers of root-eating animals are reduced most by this, but they recover faster since they reproduce faster. What can be concluded about these two species of animals? 1 They are part of the same community. 2 They are at different trophic levels. 3 They occupy different habitats. 4 They have different niches. A 1 and 2 only B 1 and 4 only C 2, 3 and 4 only D 1, 3 and 4 only
