The boxes on the left contain the names of glands which secrete enzymes. The boxes on the right contain the names of digestive enzymes. Some glands produce more than one enzyme. Draw lines to link each gland with the enzyme or enzymes it produces. Draw four lines. One has been drawn for you. salivary glands gland pancreas glands in the stomach lining amylase enzyme lipase protease

shows a diagram of the heart. A B C D E Complete by adding names to the label lines. Choose names from this list: aorta atrium muscular wall pulmonary artery pulmonary vein septum vena cava ventricle State the name of the heart chamber that pumps blood to the lungs. The volume of blood the heart pumps out per minute is called the cardiac output. shows how the cardiac output changes for students F and G as exercise increases. cardiac output / dm3 per min 15 at maximum exercise exercise intensity at rest student F student G Use to state the cardiac output for student F when resting and when doing maximum exercise. when resting when doing maximum exercise Calculate the percentage increase in cardiac output of student G from rest to maximum exercise. Show your working. % Suggest two ways the activity of the heart changes to produce an increase in cardiac output. During exercise, student F has a higher cardiac output than student G. Suggest one reason for this difference.

Choose your answers from the following words or phrases: effector motor neurone receptor relay neurone sensory neurone Write your answers in Table 3.1. Table 3.1 letter name H J K On , draw a small circle around one synapse. State two characteristics of a reflex action. shows what happens when a person picks up a hot object. very hot Use to suggest why reflex actions are important.

The boxes on the left contain the names of cells and tissues specialised for carrying out a particular function. The boxes on the right contain descriptions of specialised functions. Draw one straight line to link each specialised cell or tissue with its correct function. An example has been done for you. cell or tissue function ciliated cells absorption of water root hair cells transport of oxygen red blood cells movement of mucus phloem transport of sucrose xylem phagocytosis egg cells reproduction white blood cells transport of water

Define the term species. Table 5.1 shows the names of vertebrate groups and some of their characteristics. Place a tick in the boxes to show if the characteristic is commonly present in that group. The characteristics of the fish group have been done for you. Table 5.1 group of vertebrates characteristic fish amphibians reptiles birds mammals have feathers over most of the body have scales over most of the body lay eggs maintain a constant body temperature young are fed on milk

State the word equation for photosynthesis. A plant needs chlorophyll to photosynthesise. Name the part of a plant cell that contains chlorophyll. State two types of specialised cell that contain chlorophyll. In an investigation, some students placed a plant in bright light. They measured the rate of photosynthesis at different temperatures. The results are shown in . rate of photosynthesis / arbitrary units temperature / °C Describe the results shown in . Suggest an explanation for these results. Predict the effects on the rate of photosynthesis if the investigation is carried out at 60 °C. Explain your reason. prediction reason

Choose words or phrases from the list to complete the sentences about the enhanced greenhouse effect. Each word or phrase may be used once, more than once or not at all. carbon dioxide carbon monoxide deforestation flooding egestion methane nitrogen photosynthesise respire water vapour The enhanced greenhouse effect leads to climate change. One reason for this increased effect is that many trees are cut down. Cutting down large areas of trees is called . When trees are cut down they cannot and so the concentration of in the atmosphere increases. Another gas that increases the greenhouse effect is . Describe two reasons why humans cut down trees. An increase in some greenhouse gases is one undesirable effect of cutting down trees. State two other examples of these undesirable effects.

State the number of different secondary consumers in this food web. secondary consumers Name the organism that is both a secondary and a tertiary consumer. State what would happen to the number of hawks if the snakes in this food web all died. Explain your answer. number of hawks explanation The food web shown in changed when eagles moved into the area. Eagles eat snakes and lizards. Add this information to . You do not need to draw an eagle. State one factor that will increase the eagle population and one factor that will decrease the eagle population. increase decrease Define the term population.
