• Use the diagram below to answer this question.
• Euglena are single-celled organisms. The
  flagellum helps the organism move through water.
  Euglena are similar to plants in the way they
  obtain their food. Nina kept several euglena in
  a glass jar. She wondered what would happen if
  she covered the top half of the jar with black
  paper and placed it in sunlight. Which is the
  best prediction of how the euglena will respond
  to the change in the jar environment?
• A. Most of the euglena will move to the bottom
  half of the jar.
• B. Most of the euglena will move to the top half
  of the jar.
• C. The euglena will spread out evenly throughout
  the jar.
• D. The euglena will move back and forth between
  both halves.
