Read the sample experiment and answer the question below. Juan believes that mice exposed to radio waves will become extra strong. He decides to prove this through an experiment by designing two setups. The first set up is composed of seven mice placed near a turned-on radio for five hours. The second set up is composed of another seven mice which are not exposed to a radio waves coming from a radio. His test also consists of heavy block of wood that block access to the mouse food. He finds in the first set up, six out seven mice exposed to radio waves are able to push the blocks away. Meanwhile, four out seven mice that are not exposed to radio waves are able to do the same.

3. What is the experimental group in the experiment? 4. Identify the independent variable. 5. Give the dependent variable. 6. What are the control variables in the experiment? 7. Is the hypothesis accepted or rejected? Why?

Jewelweed, a flowering plant, has seed pods that burst open when touched and forcefully eject their seeds. these structures are favorable because they a. can cause genetic changes to occur. b. prevent germination within the seed pod. c. aid in the dispersal of the species. d. attract insects that aid in pollination.
