1. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?

• A. It is the only viable solution to the problem and should be prioritized.
• B. It is a promising approach but requires further research and development.
• C. It is less effective than traditional methods and poses environmental risks.
• D. It is irrelevant to the problem and will not make a significant impact.

Correct answer: B

Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.

2. What is the unit of force in the SI system?

• A. Newton (N)
• B. Kilogram (kg)
• C. Meter (m)
• D. Second (s)

Correct answer: A

Rationale: Force is measured in Newtons, named after Isaac Newton who formulated the laws of motion.

3. An object is thrown upwards and reaches a maximum height. Which of the following statements is TRUE about its velocity and acceleration at the peak?

• A. Velocity is zero and acceleration is maximum upwards
• B. Velocity is maximum and acceleration is zero.
• C. Velocity is maximum and acceleration is maximum upwards.
• D. Velocity is zero and acceleration is maximum downwards.

Correct answer: A

Rationale: At the peak, the object momentarily stops moving (zero velocity), but gravity still pulls it upwards, causing a maximum upward acceleration.

4. Which organelle is responsible for controlling the activities of the cell?

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

Correct answer: C

Rationale: Rationale: The nucleus is the organelle responsible for controlling the activities of the cell. It contains the cell's genetic material (DNA) and serves as the command center of the cell, regulating gene expression and directing cellular activities. The nucleus plays a crucial role in cell growth, metabolism, and reproduction. The Golgi apparatus is involved in processing and packaging proteins, the mitochondria are responsible for producing energy in the form of ATP, and ribosomes are involved in protein synthesis. However, none of these organelles have the primary function of controlling the activities of the cell like the nucleus does.

5. A new medication claims to reduce allergy symptoms by 90%. A study is conducted where 100 participants with allergies take the medication, and 90 report symptom reduction. Should this be enough evidence to recommend the medication for everyone?

• A. Yes, the study shows clear effectiveness.
• B. No, the sample size is too small.
• C. No, a control group without the medication is needed.
• D. No, long-term effects haven't been studied.

Correct answer: C

Rationale: : Comparing the medication group to a group receiving a placebo (inactive substance) would help isolate the medication's true effect and avoid attributing symptom reduction to other factors.

6. Bradycardia refers to a heart rate that is:

• A. Normal (60-100 bpm)
• B. Slightly elevated (100-120 bpm)
• C. Significantly elevated (>120 bpm)
• D. Abnormally slow (<60 bpm)

Correct answer: D

Rationale: The correct answer is D. Bradycardia refers to an abnormally slow heart rate, typically defined as being less than 60 beats per minute (bpm). A heart rate of 60-100 bpm is considered normal, not bradycardia. Choices B and C incorrectly describe elevated heart rates, which are not characteristic of bradycardia. Therefore, option D is the most accurate description of bradycardia as it signifies a heart rate that is slower than normal.
