• A. My favorite activity is playing tennis.
• B. He enjoys to travel to new places.
• C. Reading a good book is relaxing.
• D. Writing is her passion.

Correct answer: A

Rationale: Option A uses the gerund as the direct object of "is," while the other options lack a clear function for the -ing form.

2. Which of the following organelles is responsible for the production of proteins in the cell?

• A. Ribosomes
• B. Golgi apparatus
• C. Mitochondria
• D. Lysosomes

Correct answer: A

Rationale: The correct answer is A: Ribosomes. Ribosomes are the organelles responsible for protein synthesis in the cell. They are found in both prokaryotic and eukaryotic cells and can be free-floating in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the messenger RNA (mRNA) and translate the genetic code into proteins through a process called translation. The Golgi apparatus is involved in processing and packaging proteins for secretion, while mitochondria are responsible for energy production. Lysosomes are involved in digestion and waste removal within the cell.

3. What does the term "terminal velocity" refer to in physics?

• A. Maximum velocity reached by an object in free fall
• B. Velocity when the object is at rest
• C. nstantaneous velocity of an object
• D. Velocity only reached by heavy objects

Correct answer: a

Rationale: Terminal velocity is the constant velocity achieved by an object falling through the atmosphere when the force of air resistance equals the force of gravity.

4. Which word best completes the sentence: "The scientist conducted the experiment with _____ precision."

• A. extreme
• B. great
• C. utter
• D. remarkable

Correct answer: C

Rationale: Option C emphasizes the absolute and complete accuracy of the experiment.

5. The bones of the skull are classified as what type of bone?

• A. Long bone
• B. Short bone
• C. Flat bone
• D. Irregular bone

Correct answer: C

Rationale: The correct answer is C: Flat bone. The bones of the skull are classified as flat bones due to their thin, flattened shape. Flat bones provide protection to vital organs and have a broad surface for muscle attachment. Long bones, like the femur, are characterized by their elongated shape, while short bones, such as those in the wrist and ankle, are cube-shaped. Irregular bones have complex shapes and do not fit into the other bone categories. In this case, the flat bones of the skull best fit the classification.

6. Which type of muscle is characterized by voluntary control and is responsible for body movement?

• A. Cardiac muscle
• B. Smooth muscle
• C. Skeletal muscle
• D. Connective tissue

Correct answer: c

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscles are characterized by voluntary control, meaning they are under conscious control, allowing us to move our body parts as desired. These muscles are attached to bones and are responsible for movements such as walking, running, and lifting objects. Cardiac muscle (A) is found in the heart and is involuntary, while smooth muscle (B) is found in internal organs and is also involuntary. Connective tissue (D) provides support and structure to the body but is not responsible for body movements.
