1. Which type of cell division is responsible for sexual reproduction?

• A. Mitosis
• B. Meiosis
• C. Amitosis
• D. Cytokinesis

Correct answer: B

Rationale: Rationale: Meiosis is the type of cell division responsible for sexual reproduction. During meiosis, a single cell undergoes two rounds of division to produce four daughter cells, each with half the number of chromosomes as the parent cell. This reduction in chromosome number is essential for sexual reproduction, as it ensures that when two gametes (sperm and egg) combine during fertilization, the resulting zygote will have the correct number of chromosomes. Mitosis, on the other hand, is a type of cell division that produces two daughter cells with the same number of chromosomes as the parent cell and is involved in growth, repair, and asexual reproduction. Amitosis is a rare form of cell division that does not involve the typical processes of mitosis or meiosis. Cytokinesis is the process of dividing the cytoplasm of a cell after mitosis or meiosis.

2. A table shows the blood pressure readings for different age groups. How do you determine the patient with the highest systolic pressure?

• A. Find the largest number in the "systolic pressure" column.
• B. Compare the means (averages) of each age group.
• C. Add all systolic pressure values and divide by the total number of patients.
• D. Subtract the lowest systolic pressure from the highest.

Correct answer: A

Rationale: The best way is to compare the average systolic pressure values for each age group to identify the highest.

3. Which sentence uses parallel structure correctly?

• A. I enjoy reading, watching movies, and to spend time with friends.
• B. Reading, watching movies, and spending time with friends are all activities I enjoy.
• C. like to read, watch movies, and spend time with friends.
• D. Reading, movies, and friends are all things I enjoy.

Correct answer: B

Rationale: Parallel structure means using the same grammatical form for elements in a list. Option (b) uses parallel gerunds ("reading," "watching," "spending"), making it the correct choice.

4. Which element shares the same group (family) on the periodic table with helium (He)?

• A. Neon (Ne)
• B. Boron (B)
• C. Carbon (C)
• D. Oxygen (O)

Correct answer: A

Rationale: Neon (Ne). Both He and Ne belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells.

5. When an atom gains or loses electrons, it becomes a(n):

• A. Molecule
• B. Isotope
• C. Ion
• D. Compound

Correct answer: C

Rationale: Gaining or losing electrons alters the atom's electron count and charge, creating a positively or negatively charged ion.

6. Colligative properties of solutions depend on the...

• A. Concentration of the solvent
• B. All of the 3 answers given
• C. Chemical identity of the solute
• D. Number of solute particles in solution

Correct answer: D

Rationale: The correct answer is D: 'Number of solute particles in solution.' Colligative properties, such as boiling point elevation and freezing point depression, depend on the number of solute particles present in a solution, not on the chemical identity of the solute or the concentration of the solvent. This is because the presence of solute particles disrupts the solvent's normal behavior, affecting these properties. Therefore, the number of solute particles in solution directly influences colligative properties, making it the most accurate choice among the options provided.
