1. Temperature is a form of energy, whereas heat is a measurement of the intensity of the temperature.

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

Correct answer: A

Rationale: The statement is true. Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the transfer of energy from a hotter object to a colder one. Heat is not a measurement of the intensity of temperature, but rather the energy transfer due to a temperature difference. Therefore, the correct answer is True. Choice B (False) is incorrect as the statement is true based on the definitions of temperature and heat.

2. Does the diaphragm separate the thoracic and abdominopelvic cavities?

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

Correct answer: A

Rationale: The correct answer is A: True. The diaphragm is a dome-shaped muscle that separates the thoracic cavity, which contains the heart and lungs, from the abdominopelvic cavity, which contains organs such as the stomach, liver, and intestines. It plays a crucial role in breathing by contracting and relaxing to help with the process of respiration. Therefore, the statement is accurate. Choice B is incorrect because the diaphragm indeed separates these two cavities. Choice C is incorrect as the information provided allows one to determine the correct answer. Choice D is incorrect as the correct answer is 'True.'

3. Living organisms use oxygen to __________________.

• A. reduce heat production
• B. accept electrons for cellular metabolism
• C. release energy stored in the molecules of food
• D. remove metabolic wastes

Correct answer: C

Rationale: The correct answer is C. Living organisms use oxygen to release energy stored in the molecules of food through a process called cellular respiration. This process involves breaking down glucose molecules in the presence of oxygen to produce energy in the form of ATP. Choice A is incorrect because oxygen does not directly reduce heat production in organisms. Choice B is incorrect because oxygen is involved in accepting electrons rather than donating them in cellular metabolism. Choice D is incorrect because the removal of metabolic wastes is not the primary role of oxygen in living organisms.

4. The organ systems responsible for integration and coordination are the nervous and endocrine systems.

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

Correct answer: A

Rationale: The correct answer is True. The nervous and endocrine systems are indeed responsible for integration and coordination in the body. The nervous system uses electrical impulses to send signals quickly, while the endocrine system uses hormones to send chemical messages more slowly. Together, they work to regulate various bodily functions and maintain homeostasis. The other choices are incorrect as the statement accurately describes the roles of the nervous and endocrine systems in integration and coordination.

5. Which of the following may indicate hypersecretion of thyroid hormone?

• A. weight loss
• B. Bradycardia
• C. cold intolerance
• D. lethargy

Correct answer: A

Rationale: Weight loss is a common symptom of hyperthyroidism, which is characterized by an excess secretion of thyroid hormone. This increased metabolic rate can lead to weight loss despite normal or increased appetite. Bradycardia (slow heart rate), cold intolerance, and lethargy are more commonly associated with hypothyroidism, where there is an insufficient production of thyroid hormone. Therefore, choices B, C, and D are incorrect in the context of hypersecretion of thyroid hormone.
