1. Are the ears lateral to the eyes?

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: True. Lateral means towards the side or away from the midline. In human anatomy, the ears are located on the sides of the head, which is indeed lateral to the eyes that are positioned more towards the front of the face. Therefore, the statement that the ears are lateral to the eyes is true. Choice B is incorrect because the ears are not positioned closer to the midline than the eyes. Choice C is incorrect as the relationship between the ears and eyes in terms of lateral positioning can be determined anatomically. Choice D is incorrect as there is a clear anatomical relationship between the ears and eyes.

2. In all organisms, what is the basic unit of structure and function?

• A. the atom
• B. the molecule
• C. the macromolecule
• D. the cell

Correct answer: D

Rationale: The correct answer is 'the cell.' Cells are considered the basic unit of structure and function in all living organisms. While atoms are the smallest units of matter, they do not represent the basic unit of structure and function in organisms. Molecules are made up of atoms and can vary in size and complexity, but they are not the fundamental unit of life. Macromolecules are large molecules essential for life processes, but they are composed of atoms and do not function as the basic unit of structure and function in organisms. Therefore, the cell, with its organelles and specialized functions, is the correct answer.

3. Which of the following is a result of stimulation of the sympathetic nervous system?

• A. decreased blood flow to the skeletal muscles
• B. increased cardiac output
• C. decreased respiratory rate
• D. increased urinary output

Correct answer: B

Rationale: Stimulation of the sympathetic nervous system leads to an increase in cardiac output. When the sympathetic nervous system is activated, it causes the heart to beat faster and with more force, leading to an increased cardiac output. Choices A, C, and D are incorrect because the sympathetic nervous system does not cause decreased blood flow to the skeletal muscles, decreased respiratory rate, or increased urinary output.

4. Which of the following processes is most important for the continuation of the human species?

• A. Responsiveness
• B. Movement
• C. Reproduction
• D. Respiration

Correct answer: C

Rationale: Reproduction is the most important process for the continuation of the human species as it involves the creation of new individuals. Without reproduction, the human species would cease to exist. Responsiveness and movement are essential for individual survival and functioning but do not directly impact the continuation of the species. Respiration is crucial for obtaining energy but is not directly linked to the continuation of the species.

5. Which of the following structures of the gastrointestinal system absorbs iron and bile salts?

• A. Ileum
• B. Jejunum
• C. Colon
• D. Duodenum

Correct answer: A

Rationale: The correct answer is the Ileum. The Ileum is the final section of the small intestine where the absorption of key nutrients such as iron and bile salts occurs. The Jejunum mainly absorbs nutrients like carbohydrates and proteins, while the Duodenum primarily facilitates the absorption of minerals and vitamins. The Colon's main function is to absorb water and electrolytes, not iron and bile salts. Therefore, choices B, C, and D are incorrect.
