4 ARTHRITIS Read the information about arthritis. Then answer the questions. Many people get arthritis as they get older. Arthritis makes joints feel painful and stiff. Arthritis happens when the cartilage covering the bones at a joint gets damaged. It becomes rough, instead of being smooth and slippery. Sometimes, the cartilage is so badly damaged that it does not cover the ends of the bones. Each time the bones move, they rub against each other. The joints that are most often affected are the knees, fingers and hips. Artificial joints are sometimes used to replace damaged joints. Artificial joints are made of metal and plastic. One metal that is often used is titanium. This metal does not react with the fluids inside the body. The surfaces of the artificial joints are very smooth. Q1. Describe what happens to a joint to cause arthritis. Q2. Explain why arthritis makes it more difficult to move a joint.

5 PASTEURISATION Read the information below, and then answer the questions that follow. In 1856, Louis Pasteur was visited by a factory owner called Bigo. Bigo s factory made alcohol from sugary liquids, such as beet juice. This is called fermentation. But Bigo had a problem. Some of the beet juice was going sour, instead of turning into alcohol. Bigo asked Pasteur to find out why this was happening. At that time, no-one knew what made sugary liquids like beet juice turn into alcohol. Most people thought it was a simple chemical reaction. Pasteur first read all the information that he could find about fermentation. He read that, 20 years earlier, a scientist had looked at fermenting fruit juice down a microscope. The scientist had seen tiny particles, with buds growing from them. They were yeast cells. Pasteur looked at Bigo s beet juice under the microscope. In the beet juice that was producing good quality alcohol, he could see only yeast cells. But in the beet juice that was turning sour, he could also see smaller, rod-shaped micro-organisms. Pasteur did experiments to show that the beet juice only turned into alcohol when yeast was present. This was the first time that anyone had proved that fermentation was caused by micro-organisms. Q1. What was the problem that Bigo asked Pasteur to help with? Q2. How did Pasteur begin his research into Bigo s problem?

6 Q3. Pasteur concluded that yeast caused the beet juice to turn into alcohol. What evidence did he have for this conclusion? Evidence that other people had found: SORTING PLANTS INTO GROUPS The drawings show four plants. For each plant, say which of these groups it belongs to: mosses ferns conifers flowering plants Describe the features of the plant that helped you to decide which group it belongs to. Group...

7 LICHENS Lichens are small, plant-like organisms. They can often be found growing on stones, rocks and tree branches. Lichens are affected by sulfur dioxide. Some kinds of lichens are killed by very small concentrations of sulfur dioxide. Other kinds can grow in higher concentrations of sulfur dioxide. The table shows the maximum concentration of sulfur dioxide in which six kinds of lichen can grow. Lichens Maximum concentration of sulfur dioxide in which it can grow / micrograms per cubic metre A 170 B 125 C 60 D 50 E 30 F 5 Q1. Which lichen can grow in the highest concentration of sulfur dioxide?... Q2. Which lichens can grow in a sulfur dioxide concentration greater than 70 micrograms per cubic meter?... Q3. Which lichens can grow only in a sulfur dioxide concentration less than 40 micrograms per cubic meter?...

8 HAZARD SYMBOLS Draw a line from each hazard warning label to the explanation that matches it. You may need to use the internet or reference books to find some of the answers. Hazard warning label Explanation A substance that can cause harm. A substance that gives off a large amount of heat, when in contact with other substances. A substance that can explode if it comes in contact with a flame or heat. A substance that can poison you.

Adaptations for movement Example 1 Example 2 Example 3 Streamlined Shape Oar Like legs Air sacs Swim Bladder Flattened shapes Abundant bristles Suckers Adaptations for breathing With gills Without gills

10 ENERGY FOR LIFE 1. Add the name of a plant in the blank box next to the sun. It shows the energy trapped by the plants. 2. Add the name of some herbivore in the next box. The arrows to the herbivores show that the trapped energy from the plant now passes on to the herbivore. 3. Add the name of some carnivore in the box below that of herbivore. This arrow now indicates that energy has finally travelled from herbivores to carnivores. GRASS PLANKTON FISH SHARK
