1. What type of clause is "as the sun dipped below the horizon" in the sentence "We sat on the beach, as the sun dipped below the horizon"?

• A. Independent clause
• B. Subordinate clause
• C. Appositive clause
• D. Noun clause

Correct answer: B

Rationale: The clause "as the sun dipped below the horizon" provides additional information about the main clause "We sat on the beach," making it a subordinate clause.

2. How does an unbalanced force affect an object at rest?

• A. It maintains the object's state of rest
• B. It does not affect the object's rest
• C. It moves the object into motion
• D. It decreases the object's mass

Correct answer: c

Rationale: An unbalanced force acting on an object at rest causes it to start moving.

3. The measurable electrical activity of the brain is recorded by a:

• A. CAT scan
• B. MRI scan
• C. Electroencephalogram (EEG)
• D. X-ray

Correct answer: C

Rationale: The correct answer is C: "Electroencephalogram (EEG)". An EEG is a non-invasive test that measures the electrical activity of the brain by placing electrodes on the scalp. It is specifically designed to record brain wave patterns, making it a valuable tool in diagnosing conditions such as epilepsy, sleep disorders, and brain injuries. A CAT scan (A) and MRI scan (B) are imaging techniques that show the structure of the brain, while an X-ray (D) is not typically used to measure brain electrical activity.

4. Muscle tissue is responsible for movement. Which type of muscle tissue is found in the heart?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is a specialized type of muscle tissue found in the heart. Unlike skeletal muscle, which is under voluntary control, and smooth muscle, which is found in the walls of internal organs and blood vessels, cardiac muscle is involuntary and responsible for the rhythmic contractions of the heart to pump blood throughout the body. Therefore, cardiac muscle is the specific type of muscle tissue found in the heart, making it the correct choice for this question.

5. 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.

6. Which of the following substances is a common base found in household products?

• A. Sodium chloride (NaCl)
• B. Ammonia (NH₃)
• C. Vinegar
• D. Lemon juice

Correct answer: b

Rationale: Ammonia is a common base found in household products. The other choices are acids.
