They have different genetic variations than the other bacteria. They are able to reproduce faster than the other bacteria. 16 How do plants and animals get the food their cells need for energy? Plants produce their own food, while animals eat other animals or plants. Plants absorb their food through their roots, while animals produce their own food. Plants get their food by changing carbon dioxide in the atmosphere to carbon, while animals get their food through photosynthesis. RELESED 9

13 NEXTEND2 GRDE 8 S IENE RELESED F ORM 21 Why are large numbers of fish usually found in areas of upwelling? There is a large amount of food in those areas. There is less oxygen in the waters of those areas. There are fewer predators living in those areas. 22 Which will most likely result if hot water is continually dumped into a stream? Nitrate levels in the stream will increase. Dissolved-oxygen levels in the stream will decrease. Phosphorus levels in the stream will decrease. RELESED 12

14 NEXTEND2 GRDE 8 S IENE RELESED F ORM 23 Why is chlorine added to swimming pools? to kill bacteria in the water to make the water blue to make the water taste better 24 Which statement is true about undisturbed layers of rocks on the side of a mountain? The rock layers closest to ground level have more fossils than in the top layers. The layers of rocks closest to ground level are older than the layers at the top. The layers of rocks that are the darkest in color are older than those that are lighter. RELESED 13

15 NEXTEND2 GRDE 8 S IENE RELESED F ORM 25 Which is true about the continents of the world? They have the same climate. They are slowly moving along tectonic plates. They are all near the equator. 26 Which is a treatment for bacterial diseases? penicillin pills antiseptic soap alcohol wipes RELESED 14

16 NEXTEND2 GRDE 8 S IENE RELESED F ORM 27 What is the best way people can avoid diseases caused by viruses? taking aspirin injecting antibiotics getting vaccinated 28 Which would least likely influence global climate changes? producing energy using hydroelectric plants producing energy using coal producing energy using oil RELESED 15

17 NEXTEND2 GRDE 8 S IENE RELESED F ORM 29 Foxes often prey on rabbits for food. If all of the foxes are taken from the environment, what will most likely happen to the population of rabbits?
