Correct Answer: B

Rationale: In mitosis, sister chromatids are separated and move to opposite poles during Anaphase. This is when the spindle fibers shorten, pulling chromatids apart. Metaphase is when chromosomes align in the middle. Telophase is when the nuclear envelope reforms. Cytokinesis is the division of the cytoplasm. Therefore, B is correct as it specifically describes the phase where sister chromatids separate and move to opposite poles.

Correct Answer: A

Rationale: The correct answer is A because the atomic number represents the number of protons in the nucleus of an atom, which determines the element's identity. The mass number is the total number of protons and neutrons in the nucleus, indicating the atom's mass. The number of electrons is not directly related to either the atomic or mass number, eliminating choices B and D. Choice C is incorrect because the atomic number specifically refers to the number of protons, not neutrons. Thus, choice A is the only accurate explanation of the difference between the atomic number and the mass number.

Correct Answer: B

Rationale: The correct answer is B: Edema. Edema is the condition characterized by swelling caused by a buildup of lymph fluid. Lymph fluid can accumulate in tissues due to various reasons such as lymphatic system blockages or underlying medical conditions. Anemia (A) is a condition characterized by a deficiency of red blood cells or hemoglobin. Hypertension (C) is high blood pressure, not related to lymph fluid buildup. Diabetes (D) is a metabolic disorder affecting blood sugar levels, not directly related to lymph fluid accumulation. In this case, edema is the most appropriate choice as it specifically addresses the swelling caused by lymph fluid buildup.

Correct Answer: D

Rationale: The correct answer is D: Dependent, y. In experimental design, the dependent variable is the variable being measured as a possible effect, and it is typically plotted on the y-axis of a graph. This variable is what researchers are observing or testing to see if it changes in response to the manipulation of the independent variable. The independent variable, on the other hand, is what is being manipulated or controlled in the experiment and is usually plotted on the x-axis. Therefore, in a standard experimental design setup, the dependent variable is represented on the y-axis to show the relationship between it and the independent variable on the x-axis. Choices A, B, and C are incorrect because they do not align with the conventional practice of plotting the dependent variable on the y-axis.
