1. Which property of a wave represents the distance between two successive identical points on a wave?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Period

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

2. A baseball is thrown into the air. At the peak of its trajectory, which of the following forces is acting on the ball?

• A. Only gravitational force
• B. Only the force of air resistance
• C. Both gravitational force and the force of air resistance
• D. Neither gravitational force nor the force of air resistance

Correct answer: A

Rationale: At the peak, the ball momentarily stops moving upwards. Its inertia keeps it moving horizontally, but there is no force propelling it upwards except for gravity pulling it down.

3. Which of the following is NOT a characteristic of living organisms?

• A. Made up of cells
• B. Able to reproduce
• C. Require energy
• D. Non-motile

Correct answer: D

Rationale: Rationale: A) Made up of cells: All living organisms are composed of one or more cells. This is a fundamental characteristic of life as defined by cell theory. B) Able to reproduce: One of the key characteristics of living organisms is their ability to reproduce and pass on genetic information to offspring. C) Require energy: Living organisms require energy to carry out various life processes such as growth, reproduction, and maintenance of homeostasis. This energy is obtained through processes like metabolism. D) Non-motile: While some living organisms may be non-motile (unable to move on their own), movement is a common characteristic of many living organisms. Motility allows organisms to respond to their environment, find food, escape predators, and carry out other essential activities.

4. What is the Golgi apparatus?

• A. A network of tubules that transport proteins and lipids throughout the cell
• B. A sac-like structure that stores water and nutrients
• C. The site of protein synthesis
• D. The site of protein modification and packaging

Correct answer: D

Rationale: Rationale: The Golgi apparatus is an organelle in the cell responsible for modifying, sorting, and packaging proteins and lipids for transport to their final destinations. It consists of a series of flattened sacs called cisternae and plays a crucial role in processing proteins synthesized in the endoplasmic reticulum. Option A is incorrect because the network of tubules that transport proteins and lipids throughout the cell is typically associated with the endoplasmic reticulum. Option B is incorrect as the structure described is more characteristic of a vacuole, which stores water and nutrients. Option C is incorrect as protein synthesis primarily occurs in the ribosomes, not the Golgi apparatus.

5. What is the term for a solution with a pH value less than 7?

• A. Acidic
• B. Neutral
• C. Alkaline
• D. Basic

Correct answer: a

Rationale: Solutions with a pH less than 7 are acidic. The other choices do not accurately describe solutions with a pH less than 7.

6. Muscle soreness after exercise is often caused by microscopic tears in muscle fibers. This is called

• A. Atrophy
• B. Hypertrophy
• C. Dom (Delayed Onset Muscle Soreness)
• D. Spasm

Correct answer: C

Rationale: Muscle soreness after exercise is commonly caused by microscopic tears in muscle fibers, leading to a condition known as Delayed Onset Muscle Soreness (DOMS). Atrophy refers to the shrinking of muscle due to inactivity or lack of use, which is not the cause of muscle soreness after exercise. Hypertrophy is the increase in muscle size through exercise, not related to muscle soreness. Spasm is a sudden, involuntary muscle contraction unrelated to the micro-tears that cause muscle soreness. Therefore, the correct answer is C, DOMS, as it specifically addresses the micro-tears in muscle fibers that result in post-exercise soreness.
