Water potential in root hairs and the soil is equal. Water potential in root hairs and xylem is equal. Water potential in root hairs is higher than in the soil. Water potential in root hairs is lower than in the soil. 3 Which process may require energy from respiration? movement of carbon dioxide into the alveoli movement of oxygen into red blood cells uptake of glucose by cells in the villi uptake of water by root hair cells ULES /01/M/J/05

In which tissue are sugars and amino acids transported? 12 young plant may wilt when dug up and re-planted in another place. What causes this? The leaves lose less water. The roots cannot take up mineral salts. The stem cannot transport water. The surface area of the root is reduced. ULES /01/M/J/05 [Turn over

8 17 The test-tube contains glucose and yeast in water. tap 8 glucose and yeast in water X coloured liquid The tap is closed and the yeast respires anaerobically. What is observed at X and which explanation is correct? observation at X explanation liquid level falls carbon dioxide is produced liquid level falls oxygen is used liquid level rises carbon dioxide is produced liquid level rises oxygen is used 18 Fitness training increases the concentration of lactic acid that runners can build up in their muscles before pain stops them running. What is a consequence of this increase? erobic respiration in muscles can be more rapid. lood flow to the muscles is increased. More anaerobic respiration can take place in muscles. More energy is needed by the muscles. ULES /01/M/J/05

In which vessel will the blood contain the lowest concentration of urea? 9 liver kidney 20 The graph shows changes in a person s body temperature plotted against time. body temperature / o X Y time / minutes What causes the change in temperature between X and Y? increased air temperature increased evaporation of sweat reduced blood flow through surface capillaries shivering 21 Why does emphysema cause severe breathlessness? The alveoli become coated with tar. The cilia lining the trachea are destroyed. The lungs become cancerous. The surface area of the lungs is reduced. ULES /01/M/J/05 [Turn over
