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. In a normally functioning cardiovascular system, where does the heartbeat originate?

• A. Atrioventricular nodes
• B. Bundle of His
• C. Purkinje fibers
• D. Sinoatrial node

Correct answer: D

Rationale: The correct answer is the Sinoatrial (SA) node. The SA node is known as the natural pacemaker of the heart as it initiates the electrical impulses responsible for the heartbeat. The other choices, such as the Atrioventricular (AV) nodes, Bundle of His, and Purkinje fibers, are involved in conducting the electrical signals generated by the SA node to coordinate the heart's contractions. Therefore, they do not serve as the primary origin of the heartbeat.

3. An anatomical section that separates the body into right and left portions is a _______ section.

• A. frontal
• B. transverse
• C. coronal
• D. sagittal

Correct answer: D

Rationale: The correct answer is 'sagittal.' A sagittal section divides the body into right and left portions. Choice A, 'frontal,' is incorrect as it divides the body into front and back portions. Choice B, 'transverse,' divides the body into upper and lower portions. Choice C, 'coronal,' divides the body into anterior and posterior portions. Therefore, 'sagittal' is the most appropriate term for a section separating the body into right and left portions.

4. The origin of the term 'anatomy' is related to

• A. the Greek word for 'function.'
• B. the name of the first anatomist.
• C. the Greek word for 'cutting up.'
• D. the function of internal organs.

Correct answer: C

Rationale: The correct answer is C: the Greek word for 'cutting up.' The term 'anatomy' originates from the Greek words 'ana' (up) and 'temnein' (to cut), which means 'cutting up' or 'dissection.' This term refers to the process of dissecting bodies to study their structure. Choices A, B, and D are incorrect because 'anatomy' is not related to the Greek word for 'function,' the name of the first anatomist, or the function of internal organs, but rather to the act of cutting up for study and examination.

5. Is a cell the basic unit of structure and function of an organism?

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

Correct answer: A

Rationale: The correct answer is A: True. A cell is indeed the basic unit of structure and function of an organism. Cells are the smallest independently functioning unit in the structure of an organism and carry out vital functions necessary for life. Choice B, False, is incorrect because cells are universally recognized as the fundamental unit of life. Choice C, Not Sure, is incorrect as the role of a cell as the basic unit of an organism's structure and function is a well-established scientific fact. Choice D, None of the above, is incorrect as the statement provided in the question is true.
