1. What is assimilation?

• A. changing absorbed substances into different chemical forms
• B. breaking down foods into nutrients that the body can absorb
• C. eliminating waste from the body
• D. an increase in body size without a change in overall shape

Correct answer: A

Rationale: Assimilation is the process of changing absorbed substances into different chemical forms. It occurs after nutrients from food are absorbed into the bloodstream and used by the body. Choice B, breaking down foods into nutrients that the body can absorb, refers to the process of digestion rather than assimilation. Choice C, eliminating waste from the body, describes the process of excretion. Choice D, an increase in body size without a change in overall shape, does not accurately define assimilation.

2. What is the maximum capacity of a normal adult bladder before involuntary micturition is likely to occur?

• A. 800-900ml
• B. 300-600ml
• C. 1000-2000ml
• D. 400-700ml

Correct answer: B

Rationale: The correct answer is B: 300-600ml. A normal adult bladder can hold approximately 300-600ml of urine before the urge to urinate becomes strong and involuntary micturition is likely to occur. Choice A (800-900ml), Choice C (1000-2000ml), and Choice D (400-700ml) all exceed the typical capacity of a normal adult bladder and would generally not be accurate in the context of involuntary micturition.

3. Specialized cell types organized in a way that provides a specific function form

• A. tissues, which build organs.
• B. organs, which build tissues.
• C. organ systems, which build tissues.
• D. atoms, which comprise tissues.

Correct answer: A

Rationale: The correct answer is 'tissues, which build organs.' Specialized cell types organize to form tissues, which in turn build organs. Tissues are groups of cells that work together to perform a specific function. Option B is incorrect because organs are composed of tissues, not the other way around. Option C is incorrect as organ systems consist of multiple organs working together, not building tissues. Option D is incorrect as atoms are the basic building blocks of matter and are not directly involved in forming tissues.

4. 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.

5. Reproduction is the change in body characteristics over time.

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: Reproduction is the process by which living organisms produce offspring of the same kind. It is not related to changes in body characteristics over time. Therefore, the statement is false. Choices C and D are also incorrect as they do not align with the definition of reproduction.
