1. The electrical conductivity of a strong acid solution is higher than that of a weak acid solution because:

• A. Strong acids are more concentrated.
• B. Strong acids release more hydrogen ions
• C. Weak acids are better at dissolving salts.
• D. Strong acids have a lower pH.

Correct answer: B

Rationale: Strong acids completely dissociate, leading to a h

2. The fluid-filled, jelly-like substance within the cell that suspends the organelles is called the:

• A. Nucleus
• B. Cytoplasm
• C. Plasma membrane
• D. Golgi apparatus

Correct answer: B

Rationale: The correct answer is B: Cytoplasm. Cytoplasm is the fluid-filled, jelly-like substance within the cell that suspends the organelles. It is where many cellular processes take place, such as metabolism and protein synthesis. The nucleus (option A) is the organelle that contains the cell's genetic material, the plasma membrane (option C) is the outer boundary of the cell that regulates what enters and exits the cell, and the Golgi apparatus (option D) is involved in processing and packaging proteins. Understanding the functions of each organelle is crucial in recognizing that the cytoplasm is the correct answer in this context.

3. The WBC (white blood cell) type responsible for the initial attack on pathogens is:

• A. Red blood cells
• B. Platelets
• C. Phagocytes
• D. Lymphocytes

Correct answer: C

Rationale: The correct answer is C: Phagocytes. Phagocytes are a type of white blood cell that plays a crucial role in the immune response by engulfing and destroying pathogens. They are the first line of defense against invading microorganisms, initiating the initial attack on pathogens. Red blood cells (option A) are responsible for carrying oxygen, not for immune responses. Platelets (option B) are involved in blood clotting. Lymphocytes (option D) are another type of white blood cell but are mainly responsible for specific immune responses rather than the initial attack on pathogens.

4. ch 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: Elements within the same group share similar electron configurations in their outermost shells, resulting in comparable chemical properties. Helium and Neon both belong to Group 18 (Noble Gases), explaining their similarities.

5. What is the stage of mitosis during which the nuclear envelope reforms?

• A. Prophase
• B. Metaphase
• C. Telophase
• D. Cytokinesis

Correct answer: C

Rationale: Rationale: - Prophase is the stage of mitosis where the nuclear envelope breaks down, allowing the chromosomes to condense and become visible. - Metaphase is the stage where the chromosomes line up along the metaphase plate in the middle of the cell. - Telophase is the stage where the nuclear envelope reforms around the separated sister chromatids at opposite poles of the cell. - Cytokinesis is the final stage of cell division where the cytoplasm divides to form two daughter cells, but it is not directly related to the reformation of the nuclear envelope.

6. Which adjective best describes the following setting: "A lone cabin stood nestled amongst towering pines, smoke curling from its chimney into the crisp mountain air."

• A. Bland
• B. Urban
• C. Idyllic
• D. Sterile

Correct answer: C

Rationale: "Idyllic" captures the peaceful and picturesque nature of the setting.
