1. Identify the correct sequence of the 3 primary body planes as numbered 1, 2, and 3 in the above image.

• A. Plane 1 is coronal, plane 2 is sagittal, and plane 3 is transverse.
• B. Plane 1 is sagittal, plane 2 is coronal, and plane 3 is medial.
• C. Plane 1 is coronal, plane 2 is sagittal, and plane 3 is medial.
• D. Plane 1 is sagittal, plane 2 is coronal, and plane 3 is transverse.

Correct answer: A

Rationale: In the standard anatomical position, plane 1 (coronal/frontal plane) divides the body into anterior and posterior portions, plane 2 (sagittal plane) divides the body into left and right portions, and plane 3 (transverse/horizontal plane) divides the body into superior and inferior portions. Therefore, the correct sequence is Plane 1 as coronal, Plane 2 as sagittal, and Plane 3 as transverse, which corresponds to Choice A. Choice B is incorrect as it misidentifies the planes. Plane 2 cannot be coronal as it specifically divides the body into left and right portions. Choice C is incorrect as it misidentifies Plane 2 as sagittal when it should be coronal. Choice D is incorrect as it incorrectly designates Plane 2 as coronal when it should be sagittal, leading to an inaccurate sequence of the primary body planes.

2. Which of the following is NOT a common symptom of pregnancy?

• A. Fatigue
• B. Nausea
• C. Increased urination
• D. Loss of appetite

Correct answer: D

Rationale: The correct answer is D, 'Loss of appetite.' Loss of appetite is not a common symptom of pregnancy. In fact, many pregnant individuals experience an increase in appetite due to hormonal changes and increased energy needs during pregnancy. Fatigue, nausea, and increased urination are more commonly reported symptoms during pregnancy. Fatigue is often experienced due to hormonal changes and the body's increased metabolic demands during pregnancy. Nausea, commonly known as morning sickness, is a well-known symptom experienced by many pregnant individuals. Increased urination is a common symptom in pregnancy due to hormonal changes leading to increased blood flow to the kidneys and increased fluid processing by the body.

3. What is the product of the complete combustion of propane (C3H8)?

• A. CO2
• B. CO
• C. CH4
• D. C

Correct answer: A

Rationale: The complete combustion of propane (C3H8) results in the production of carbon dioxide (CO2) and water. When a hydrocarbon such as propane undergoes complete combustion, the carbon atoms combine with oxygen to form CO2. This makes choice A, CO2, the correct answer. Choices B, C, and D are incorrect as CO is carbon monoxide, CH4 is methane, and C is elemental carbon, none of which are the primary product of the complete combustion of propane.

4. What is the process in which RNA polymerase copies DNA into RNA, with DNA unwinding and serving as a template while RNA is assembled?

• A. Replication
• B. Transcription
• C. Translation
• D. Duplication

Correct answer: B

Rationale: The correct answer is B: Transcription. Transcription is the process where RNA polymerase reads the DNA template strand and synthesizes RNA, following the base-pairing rules. During transcription, DNA unwinds and serves as a template for the assembly of complementary RNA molecules. Replication (Choice A) is the process of making an identical copy of DNA, not RNA from DNA. Translation (Choice C) is the process of synthesizing proteins from mRNA. Duplication (Choice D) is a general term and does not specifically refer to the process described in the question.

5. What property of a wave represents the distance between two successive identical points on a wave?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Period

Correct answer: A

Rationale: The wavelength of a wave represents the distance between two successive identical points on a wave, such as two crests or two troughs. It is typically measured in meters and is a fundamental characteristic of a wave, influencing its properties and behavior. Wavelength is crucial in wave physics, affecting phenomena like interference, diffraction, and the wave's speed in a medium. Amplitude refers to the maximum displacement of a wave from its rest position, frequency is the number of complete oscillations a wave makes in a given time, and period is the time it takes for a wave to complete one full cycle. These properties are different from wavelength and serve distinct purposes in describing waves.
