1. The phrase "green alternative" suggests that bioremediation is...

• A. The most economical option for plastic cleanup.
• B. Faster and more efficient than traditional methods.
• C. Environmentally friendly and less harmful than other solutions.
• D. More aesthetically pleasing than existing approaches.

Correct answer: C

Rationale: The passage contrasts bioremediation with "traditional methods," explicitly linking it to being environmentally friendly.

2. What happens to the speed of a sound wave when it travels from air to water?

• A. It increases because water is denser.
• B. It decreases because water is denser.
• C. It remains the same.
• D. Speed depends on the frequency, not the medium.

Correct answer: A

Rationale: Sound waves travel faster in denser mediums like water compared to air due to stronger interactions between particles.

3. Which of the following is the main function of the lungs?

• A. To transport oxygen and nutrients throughout the body
• B. To coordinate movement and sensory information
• C. To filter waste products from the blood
• D. To exchange oxygen and carbon dioxide between the body and the environment

Correct answer: D

Rationale: Rationale: A) To transport oxygen and nutrients throughout the body - While the lungs do play a role in transporting oxygen, their primary function is to exchange oxygen and carbon dioxide between the body and the environment. The transportation of oxygen and nutrients throughout the body is primarily carried out by the circulatory system, specifically the blood vessels. B) To coordinate movement and sensory information - This function is primarily carried out by the nervous system, specifically the brain and spinal cord. C) To filter waste products from the blood - The kidneys are responsible for filtering waste products from the blood, not the lungs. The lungs primarily function in gas exchange.

4. Which type of nutrient requires the most complex and lengthy digestion process?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Vitamins

Correct answer: B

Rationale: Rationale: Proteins require the most complex and lengthy digestion process among the options provided. When we consume proteins, they need to be broken down into amino acids, which are the building blocks of proteins. This process starts in the stomach with the help of stomach acid and enzymes, continues in the small intestine where more enzymes break down proteins into amino acids, and finally, these amino acids are absorbed into the bloodstream for various bodily functions. Carbohydrates and fats also require digestion, but the process for breaking down proteins into amino acids is more complex and time-consuming. Vitamins, on the other hand, do not require digestion in the same way as proteins, carbohydrates, and fats, as they are already in a form that can be readily absorbed by the body.

5. What is the medical term for ingrown hair?

• A. Folliculitis
• B. Hirsutism
• C. Pseudofolliculitis Barbae
• D. Alopecia

Correct answer: C

Rationale: The correct answer is C: 'Pseudofolliculitis Barbae.' This term specifically refers to ingrown hairs commonly seen in the beard area. Folliculitis (A) is inflammation of the hair follicles, not necessarily due to ingrown hairs. Hirsutism (B) is excessive hair growth, unrelated to ingrown hairs. Alopecia (D) is hair loss, which is also not related to ingrown hairs. Therefore, 'Pseudofolliculitis Barbae' is the medical term specifically used to describe ingrown hairs in the beard area, making it the correct answer.

6. The framework of bones, cartilage, ligaments, and tendons that provides structure, support, and facilitates movement is the:

• A. Muscular system
• B. Skeletal system
• C. Nervous system
• D. Endocrine system

Correct answer: B

Rationale: The correct answer is B: Skeletal system. The skeletal system is composed of bones, cartilage, ligaments, and tendons that work together to provide structure, support, and facilitate movement in the body. The bones serve as the framework that supports and protects the body's organs, while cartilage cushions the joints. Ligaments connect bones to each other, and tendons connect muscles to bones, allowing for movement. The muscular system (choice A) consists of muscles that work with the skeletal system to produce movement. The nervous system (choice C) controls and coordinates bodily functions through the brain, spinal cord, and nerves. The endocrine system (choice D) regulates various bodily functions through the release of hormones. Therefore, the skeletal system is the correct answer as it specifically refers to the framework of bones, cartilage, ligaments, and tendons that support and enable movement in the body.
