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.
