1. Which technique best helps maintain consistency in writing style?

• A. Writing freely without a clear outline or structure.
• B. Using different vocabulary and sentence structures in each paragraph.
• C. Establishing a style guide with agreed-upon terminology and formatting.
• D. Relying on thesaurus suggestions for varied word choices.

Correct answer: C

Rationale: A style guide ensures consistency in tone, terminology, and formatting across different pieces of writing.

2. A lampshade consists of a cylindrical base (diameter 20cm, height 10cm) and a hemispherical top (same diameter as the base). What is its total surface area?

• A. 785 sq cm
• B. 1130 sq cm
• C. 1570 sq cm
• D. 2055 sq cm

Correct answer: D

Rationale: Calculate the surface area of the cylinder (base + lateral surface) and the hemisphere (half of a sphere's surface area). Add both areas to find the total surface area.

3. Which of the following is the main organ responsible for storing energy?

• A. Liver
• B. Heart
• C. Kidneys
• D. Adipose tissue

Correct answer: D

Rationale: Rationale: - Adipose tissue, commonly known as body fat, is the main organ responsible for storing energy in the form of triglycerides. - The liver plays a role in energy metabolism by regulating glucose levels and storing glycogen, but its primary function is not energy storage. - The heart is a muscular organ responsible for pumping blood throughout the body and does not play a significant role in energy storage. - The kidneys are vital organs responsible for filtering blood and regulating fluid balance, but they are not primarily involved in energy storage.

4. What is the primary difference between ionic and metallic bonding?

• A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer.
• B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional.
• C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals.
• D. Ionic bonds form discrete molecules, while metallic bonds form extended structures.

Correct answer: B

Rationale: Ionic bonds form discrete molecules, while metallic bonds form extended structures. Ionic bonds involve complete electron transfer between specific atoms, resulting in discrete molecules. Metallic bonds involve a "sea" of delocalized electrons shared across all metal atoms, leading to strong, non-directional bonding throughout the entire material.

5. Identify the bone with the greatest length in the human body.

• A. Femur (Thigh bone)
• B. Humerus (Upper arm bone)
• C. Tibia (Shin bone)
• D. Scapula (Shoulder blade)

Correct answer: A

Rationale: The femur, exceeding a meter in length, bears significant weight and enables locomotion.

6. Homologous structures are similar structures in different organisms that have a common evolutionary origin. An example is:

• A. Butterfly wings and bird wings (analogous structures with different origins)
• B. The arm of a human, the wing of a bat, and the flipper of a whale
• C. The eyes of an octopus and a human (convergent evolution with different origins)
• D. The stinger of a bee and the barb of a cactus (unrelated structures)

Correct answer: B

Rationale: Rationale: Homologous structures are similar structures found in different organisms that share a common evolutionary origin. In this case, the arm of a human, the wing of a bat, and the flipper of a whale are all examples of homologous structures. Despite serving different functions in these organisms, they share a common underlying structure due to their evolutionary relationship. These structures are evidence of a shared ancestry and are modified over time to suit the specific needs of each species. Option A (Butterfly wings and bird wings) refers to analogous structures, which have similar functions but different evolutionary origins. Option C (The eyes of an octopus and a human) describes convergent evolution, where similar traits evolve independently in different species due to similar environmental pressures. Option D (The stinger of a bee and the barb of a cactus) refers to unrelated
