EOC Check Points Nature of Science CAROLINE IS DESIGNING AN EXPERIMENT TO TEST THE HYPOTHESIS THAT EXPOSURE TO AN INCREASED LEVEL OF ULTRAVIOLET RADIATION REDUCES THE GROWTH OF CORN PLANTS. SHE HAS 200 CORN SEEDLINGS PLANTED IN TWO GROUPS OF 100 SEEDLINGS EACH. SHE IS TRYING TO DECIDE HOW MUCH WATER, FERTILIZER, AND ULTRAVIOLET RADIATION EACH GROUP SHOULD RECEIVE. WHICH OF THE FACTORS SHOULD SHE KEEP THE SAME IN BOTH PLANT GROUPS IN ORDER TO SUCCESSFULLY TEST THE HYPOTHESIS? A. AMOUNT OF FERTILIZER ONLY B. AMOUNT OF FERTILIZER AND WATER C. THE AMOUNT OF ULTRAVIOLET RADIATION ONLY D. THE AMOUNT OF FERTILIZER, WATER, AND ULTRAVIOLET RADIATION

6 EOC Check Points Comparison of Mitosis/Meiosis PLEASE KEEP EACH EOC CHECK POINTS PAGE!! These will help you review for chapter tests as well as prepare for your EOC Exam! 1-3, each correct placement is ½ pt. Complete the Venn diagram by placing each letter in the appropriate location. Each description applies to either mitosis, meiosis, or both. Mitosis Meiosis A. Results in two daughter cells that are genetically identical to the parent cell B. This type of cell division takes place in humans C. Produces gametes which allows for sexual reproduction D. Involves two consecutive cell divisions resulting in 4 daughter cells E. Results in diploid cells F. Results in haploid cells 4. Indicate what process is occurring in the figure below. 5.
