NAS2 CHALLENGE LATEST 2026 FINAL PAPER QUESTIONS
AND ANSWERS GRADED A+
✔✔Cell Theory - ✔✔•All organism are made of one or more cells
•the cell is the fundamental unit of life
•all cells come from preexisting cells
•all cell have the same basic chemical composition
•all cells use energy
•all cells contain dna that is duplicated and passed on as each cell divides
✔✔ What is the purpose of the scientific method - ✔✔to clearly do an experiment by
process of steps helping you keep track and correct any mistakes and to show others
how you got to the result that you achieved in conclusion
✔✔Identify the purpose of the scientific method - ✔✔1.Ask a question
2.Do Background research
3 Construct a hypothesis
4.test your hypothesis by doing an experiment
5 analyze your data and draw a conclusion
6. Communicate your results
✔✔What is the difference between an independent variable and and dependent variable
- ✔✔Value of an independent can be changed. You cannot change the value of
dependent variable. the independent variable is the value which is manipulated in an
experiment. The dependent variable is compared to the control group, which does not
recieve the test variable
