A gradual increase in the population of raccoons and opossums.G. A sharp decline in the population of raccoons and opossums.H. A decrease in competition for food resources for lower level consumers.I.An increase in the sightings of bird species that are prey of pythons.23 What are the effects of catching and sterilizing Burmese pythons?A. Competing predators will have more prey resources.B. There will be fewer sightings of raccoons and opossums.C. There will be an increase in predation by the pythons.D. The local ecosystems will be more imbalanced due to the absence ofthe pythons.24 What statement best explains why invasive species outcompete nativespecies in a particular ecosystem?F. The natural species are naturally weak and in need of constant humanassistance.G. Native species in North America are less evolved and therefore lessable to thrive in their native habitats than European and Asian plantsand animals.H. Human dependence on invasive species results in them beingreleased in greater numbers.Invasive species have few natural predators in their new environmentto control their population numbers.1.15Florida Science Assessment WorkbookCopyright O Pearson Education, Inc, or its affiliates.

a small round magnet from a string. Then she attaches a paper bird to the south pole side of the magnet. The north pole side of the magnet is uncovered on the back of the bird. Which of these actions would make Anita's bird move away from the object that moves toward it? A. moving the south pole end of a bar magnet toward the "bird side" the round magnet B. touching the "bird side" of the round magnet with a metal clip C. touching the "bird side" of the round magnet with a plastic pen D. moving the north pole end of a bar magnet toward the "bird side of the round magnet 20 Why do some objects cause Anita's bird to move, but other objects do NOT? F. Non-magnetic items cause the magnet to be attracted to the bird G. Magnetic items change air pressure around the bird, which causes it to move. H. A magnetic field around the bird's magnet makes a force that repels or attracts objects. 1. Temperature differences between the objects and the bird repel or attract them to each other. 21 Which of the following groups includes objects that would all be attracted to the magnet on Anita's bird? A. cotton ball, metal screw, wooden toothpick B. steel nail, metal paper clip, stainless steel fork C. metal wire, plastic straw, rubber eraser D. metal ruler, wooden pencil, paper notepad
