1. All of the following are parts of the respiratory system EXCEPT the:

Correct answer: C

Rationale: The esophagus is part of the digestive system, not the respiratory system. The trachea, bronchi, and larynx are all components of the respiratory system responsible for the passage of air during breathing and speech production. The esophagus, on the other hand, is part of the digestive system, responsible for the transportation of food from the mouth to the stomach through a series of muscular contractions called peristalsis. Therefore, the correct answer is 'Esophagus (C).' Choices A, B, and D are all integral parts of the respiratory system, playing crucial roles in the airway and vocalization processes.

2. Which of the following is an example of a tissue?

Correct answer: B

Rationale: The correct answer is 'B: liver.' The liver is an example of a tissue. Tissues are groups of cells that work together to perform specific functions in the body. The liver is made up of different types of cells that work together to carry out various essential functions, such as detoxification, metabolism, and storage of nutrients. Option A (chloroplasts) refers to organelles, not tissues. Option D (hamstring) is a muscle, not a tissue. Option C (mammal) represents a higher level of organization than tissues, as it refers to a classification of organisms, not a specific tissue type.

3. If an atom has 32 neutrons, 17 protons, and 19 electrons, what is its charge?

Correct answer: A

Rationale: An atom's charge is determined by the difference between the number of protons and electrons. Since the atom has 17 protons and 19 electrons, the net charge is positive. The excess of two electrons compared to protons results in a positive charge. Choice B (Negative) is incorrect because the atom has more protons than electrons, leading to a positive charge. Choice C (Neutral) is incorrect because the atom has an imbalance between protons and electrons, resulting in a charge. Choice D (Cannot be determined) is incorrect as the charge can be determined based on the given information.

4. Which of the following anatomical terms is not part of the knee?

Correct answer: C

Rationale: The lateral malleolus is a bony prominence on the lateral side of the ankle and is not part of the knee anatomy. The other options - medial collateral ligament, patella, and lateral meniscus - are all structures within the knee joint. The medial collateral ligament is located on the inner side of the knee, the patella is the kneecap, and the lateral meniscus is a cartilage structure within the knee joint. Therefore, the correct answer is C, lateral malleolus.

5. What is the role of the spleen in the body?

Correct answer: B

Rationale: The correct answer is B. The spleen acts as a blood filter, removing old or damaged red blood cells. It also plays a role in immune responses, storing blood reserves, and helping to fight infection. The production of bile is primarily associated with the liver, not the spleen. While the bone marrow is responsible for red blood cell production, the spleen's main functions do not include this process. Storing fat is not a primary function of the spleen.
