I cannot provide a specific answer to your question without knowing the details of the exercise on page 150 of the science textbook for 10th grade. Please provide me with the exercise or describe it in more detail so I can assist you better.
However, I can offer some general tips on how to approach science exercises:
Read the exercise carefully: Make sure you understand what is being asked before you start answering.
Identify the key concepts: What are the main ideas or principles that the exercise is trying to assess?
Brainstorm possible solutions: Think about different ways to approach the problem.
Test your solutions: Use your knowledge of science to evaluate whether your solutions are correct.
Explain your reasoning: Clearly explain your thought process and how you arrived at your answers.
Check your work: Review your answers to make sure they are complete and accurate.
Remember, practice makes perfect! The more you practice solving science exercises, the better you will become at it.
If you are still having trouble with a particular exercise, you can always ask your teacher or a classmate for help. There are also many online resources available that can provide additional support.
