5 8 Which element is found in proteins but not carbohydrates? 5 carbon hydrogen nitrogen oxygen 9 Many enzymes do not work at temperatures above 60. Which statement explains this? Product molecules are not made because the active site has changed shape. Product molecules change shape so they do not fit the active site. Substrate molecules are moving too fast. Substrate molecules are moving too slowly. 10 Which substances are used for photosynthesis? carbon dioxide and glucose carbon dioxide and water glucose and oxygen glucose and water 11 Which term is defined as the taking of substances into the body through the mouth? absorption assimilation digestion ingestion 12 Which nutrient is deficient in the diet of a child with kwashiorkor? calcium iron protein vitamin ULES /22/F/M/17 [Turn over

6 13 The diagram shows a tooth with signs of decay. 6 enamel decay What has made the hole in the enamel of the tooth? acid saliva sugar toothpaste 14 Which is a description of translocation? movement of amino acids and sucrose from sink to source movement of amino acids and sucrose from source to sink movement of water down a water potential gradient movement of water up a water potential gradient 15 Which is a function of the lymphatic system? deamination of amino acids production of lipase protection from infection transport of oxygen ULES /22/F/M/17

7 7 16 hospital patient who is feeling unwell is given a blood test. The results of the blood test show a very low level of platelets. What effect will this have? The blood will be unable to transport nutrients, hormones and carbon dioxide. The blood will not be able to carry as much oxygen to the tissues as normal. There will be a greater risk of bleeding because the blood will take longer to clot. There will be a greater risk of infection because the blood cannot make antibodies. 17 What is a common feature of both active and passive immunity? They are acquired by vaccination. They are always short-term. They involve the activity of memory cells. They involve antibodies. ULES /22/F/M/17 [Turn over

9 19 In an experiment, three glass bell jars were set up as shown in the diagram. 9 bell jar air from the lungs green plant P Q R left open to the air for 8 hours left in sunlight for 8 hours air breathed out by a student for 5 minutes t the end of the experiment, which bell jar has the most oxygen and which has the least? most oxygen least oxygen P Q P R Q P R P 20 What are the products of anaerobic respiration in muscles? ethanol and carbon dioxide ethanol only lactic acid and carbon dioxide lactic acid only 21 Which substance remains in the blood as it passes through the kidney? protein salts urea water ULES /22/F/M/17 [Turn over

10 22 The diagram shows the mechanisms that control the concentration of glucose in the blood. 10 hormone X rises gland W lowers glucose concentration normal blood glucose concentration raises glucose concentration hormone Z gland Y falls Which row identifies the glands and hormones labelled W, X, Y and Z? gland W hormone X gland Y hormone Z adrenal gland adrenaline adrenal gland glucagon adrenal gland adrenaline pancreas insulin pancreas glucagon adrenal gland insulin pancreas insulin pancreas glucagon 23 Which row shows the effects of increased adrenaline release? breathing rate pulse rate pupil decreases increases widens increases decreases widens increases increases narrows increases increases widens ULES /22/F/M/17

11 11 24 The graph shows how the rate of photosynthesis of a plant changes with light intensity, at three different carbon dioxide concentrations. In each case the temperature is % carbon dioxide rate of photosynthesis X 0.04% carbon dioxide 0.02% carbon dioxide light intensity What is the limiting factor for the rate of photosynthesis at point X on the graph? carbon dioxide concentration light intensity surface area of the plant temperature 25 What is an advantage of asexual reproduction for a population of flowering plants in the wild? disease is less likely to affect the whole population. Large numbers of offspring can be produced quickly. Pollen can easily be transferred within the same flower. The offspring show genetic variety. 26 uring sexual reproduction in plants, what will give rise to the greatest variation in the offspring? ll of the flowers on the same plant have male and female reproductive organs. The anthers and stigmas on the same plant mature at the same time of year. There are separate male and female flowers on the same plant. There are separate male and female plants.

It is involved in the digestion of the ovum cell membrane. It provides energy for movement. 28 Which hormone is given to women undergoing fertility treatment? adrenaline FSH insulin oestrogen 29 The diagram represents the fusion of sperm and ovum at fertilisation. ovum fertilisation cell X sperm Which description of cell X is correct? diploid gamete diploid zygote haploid gamete haploid zygote 30 cell with 16 chromosomes divides twice by mitosis. How many chromosomes does each of the resulting cells contain? ULES /22/F/M/17

13 13 31 man of genotype I I o and woman of genotype I I o have a child.

Selection changes the characteristics of living things. Selection is based on genetic variation. Selection is not based on adaptation to their environment. Selection occurs over many generations. 35 The diagram shows the energy present in a food chain kj photosynthesising phytoplankton 4000 kj 400 kj 40 kj krill herring bass What percentage of energy present in the producer is transferred to the secondary consumer? 0.01% 0.1% 1% 10% ULES /22/F/M/17 [Turn over

The human N is inserted into the bacterial plasmid using the enzyme 3 forming a 4 plasmid. Which row correctly completes gaps 1, 2, 3 and 4? ligase sticky ends protease restriction recombinant new N ligase daughter restriction daughter plasmids ligase diploid restriction sticky ends ligase recombinant 39 How does cutting down trees contribute to the greenhouse effect? There will be less carbon dioxide absorbed. There will be less oxygen absorbed. There will be less shade from trees. The soil will become dry. ULES /22/F/M/17
