1. Which of the following scenarios represents an example of static friction?

Correct answer: C

Rationale: The correct answer is C. Static friction occurs when two surfaces are in contact but not moving relative to each other. Pushing a stationary object involves static friction as you apply a force to overcome the friction keeping the object stationary. Choices A, B, and D involve kinetic friction, which occurs when two surfaces are moving relative to each other. Option A involves moving the box across the floor, which is an example of kinetic friction. Option B involves the movement of a car around a curve, which also relates to kinetic friction due to the relative movement between the tires and the road. Option D describes braking a car to stop, where the moving car's wheels interact with the road, creating kinetic friction to slow down and stop the car.

2. What is the correct arrangement of the small intestine segments, from the stomach to the large intestine?

Correct answer: A

Rationale: The correct arrangement of the small intestine segments, from the stomach to the large intestine, is Duodenum, Jejunum, and Ileum. The small intestine begins with the duodenum, then continues to the jejunum, and finally, it ends with the ileum before connecting to the large intestine. Option A, 'Duodenum, Jejunum, Ileum,' is the correct sequence. Choices B and C have the segments in incorrect order, not following the anatomical arrangement of the small intestine. Therefore, they are incorrect. Option D, 'None of the above,' is also incorrect as the correct sequence is provided in option A.

3. Which of the following indicates the body's draining of clear fluid throughout the body to protect it from infection?

Correct answer: C

Rationale: The correct answer is C, the Lymphatic System. The lymphatic system is responsible for draining clear fluid, known as lymph, throughout the body to protect it from infection. The other choices are incorrect because the pulmonary loop specifically refers to circulation between the heart and lungs, the systemic loop refers to circulation between the heart and the rest of the body, and the immune system is responsible for fighting infections and diseases rather than draining clear fluid.

4. Which enzyme breaks down carbohydrates like starches and sugars in the mouth?

Correct answer: C

Rationale: The correct answer is Amylase. Amylase is the enzyme responsible for breaking down carbohydrates like starches and sugars in the mouth. Pepsin is a digestive enzyme that breaks down proteins in the stomach, lipase breaks down fats, and trypsin is another enzyme that breaks down proteins in the small intestine. Therefore, choices A, B, and D are incorrect for this question.

5. When unpolarized light passes through a polarizing filter, the intensity of the transmitted light is:

Correct answer: B

Rationale: When unpolarized light passes through a polarizing filter, the filter only allows light waves oscillating in a specific direction to pass through while blocking light waves oscillating in other directions. Since unpolarized light consists of light waves oscillating in all possible directions, when it passes through a polarizing filter, only half of the light waves (those oscillating in the direction allowed by the filter) are transmitted. As a result, the intensity of the transmitted light is reduced by half. Choice A is incorrect because the light is not completely absorbed; choice C is incorrect because the polarizing filter affects the transmitted light; and choice D is incorrect because the intensity does not double, but rather decreases by half due to the selective transmission of light waves in a specific direction by the polarizing filter.
