　　Q1.

　　A group of students investigate the effect of exercise on breathing rate.

　　They measure their breathing rate at rest by counting breaths per minute.

　　They then exercise by running on the spot.

　　After exercise they measure their breathing rate by counting breaths per minute.

　　These are their results.

　　(a) Display these results in a table.

　　(b) Explain why breathing rate is higher after exercise.

　　(c) Explain how the students could improve their investigation.

　　Q2.

　　A student investigates the effect of carbon dioxide concentration on the rate of photosynthesis in a water plant.

　　The graph shows the student's results.

　　(a) Put an X on the graph to show where carbon dioxide limits the rate of photosynthesis.

　　(b) Write the word equation for photosynthesis.

　　(c) The student's method allows her to make a valid and reliable comparison of the rate of photosynthesis at different carbon dioxide concentrations.

　　(i) Give the independent variable in her investigation.

　　(ii) Suggest a variable the student needs to control in her investigation.

　　(iii) Explain how the student could make sure her results are reliable.

　　Q3.

　　The photograph shows a mammal called a mountain hare.

　　Mountain hares eat plants.

　　Foxes, cats and eagles are predators that eat mountain hares.

　　(a) (i) Use this information to draw a food web.

　　(ii) Give the name used to describe animals that eat plants.

　　(b) Scientists want to find out which type of plant habitat mountain hares prefer.

　　• They use quadrats to sample seven habitats.

　　• Each habitat contains a different type of plant.

　　• The scientists calculate the percentage of quadrats in each habitat where mountain hare

　　• faeces are found.

　　• The graph shows the results.

　　(i) Name the type of plant habitat that the mountain hares like best.

　　(ii) Suggest three reasons why mountain hares may prefer to eat the plants in some habitats rather than plants in other habitats.

　　(c) The scientists use 700 quadrats in one plant habitat and find that 224 quadrats contain mountain hare faeces.

　　(i) Calculate the percentage of quadrats containing mountain hare faeces in this habitat. Show your working.

　　(ii) Name the type of plant habitat where the scientists collected these results.

　　(d) The scientists use a large number of quadrats to make sure the data collected is reliable.

　　Describe a procedure they should follow to make sure the data collected using quadrats is valid.

　　Q4.

　　The diagram shows two types of cell division.

　　(a) Give the name of cell division A.

　　(b) Using the information in the diagram, give two differences between cell division A and cell division B.

　　(c) Name a part of a flowering plant where cell division A occurs and a part where cell division B occurs.

　　Q5.

　　Pneumoconiosis is a lung disease caused by breathing in coal dust particles.

　　The X-ray shows the lungs of a person with pneumoconiosis.

　　Coal dust particles collect in the alveoli and cannot be removed.

　　Cells grow around these coal dust particles, forming tissue that traps the particles.

　　(a) State what is meant by the term tissue.

　　(b) Suggest why pneumoconiosis reduces the ability of a person to exercise.

　　(c) In the UK, in 2013, breathing in dust particles resulted in diseases that caused 260 000 deaths.

　　The graph shows the number of these deaths caused by breathing in dust particles of asbestos, coal and silica.

　　(i) Calculate the number of deaths in the UK, in 2013, caused by breathing in dust particles other than asbestos, coal or silica.

　　(ii) Give two conclusions that can be made from the data in the graph.

　　Q6.

　　A student carries out an experiment to investigate the effect of different concentrations of a food dye on diffusion.

　　(a) Describe what is meant by the term diffusion.

　　(b) The student adds a different concentration of coloured food dye to each of five wells in an agar plate. The diagram shows the agar plate at the beginning of the experiment and after 24 hours.

　　The student does the experiment using three plates.

　　For each plate he measures the diameter of each circle to see how far the food dye has diffused. The table shows his results.

　　(i) Calculate the average diameter for 0.2% concentration of food dye.

　　(ii) Describe the effect of food dye concentration on diffusion.

　　(iii) Explain the relationship between food dye concentration and diffusion.

　　(c) State two variables that the student should control in this experiment to ensure that the results are valid.
