1. Which of the following is a tertiary consumer?

• A. Owl
• B. Shrew
• C. Grasshopper
• D. Wheat

Correct answer: A

Rationale: The correct answer is A, Owl. Tertiary consumers are organisms that feed on secondary consumers, which, in turn, feed on primary consumers. Owls are considered tertiary consumers because they primarily feed on animals such as rodents, which are secondary consumers. Shrew (choice B) is a secondary consumer, feeding on insects and worms, placing it at a lower trophic level than the owl. Grasshopper (choice C) is a primary consumer, feeding on plants. Wheat (choice D) is not a consumer in the food chain but a plant.

2. Which cut is considered a cross section?

• A. A sagittal or frontal section
• B. A cut along the coronal plane
• C. A cut along the median plane
• D. A cut through the transverse plane

Correct answer: D

Rationale: The correct answer is D: A cut through the transverse plane. A transverse plane cut, also known as a cross-section, divides the body or an organ into superior and inferior portions. This type of cut is perpendicular to the long axis of the body and is commonly used in medical imaging to display internal structures and organs in a horizontal view. Choices A, B, and C are incorrect because a sagittal or frontal section (A) divides the body into left and right portions, a cut along the coronal plane (B) separates the body into anterior and posterior parts, and a cut along the median plane (C) divides the body into equal left and right halves.

3. How many kilometers is equivalent to 200 meters?

• A. 50 kilometers
• B. 20 kilometers
• C. 12 kilometers
• D. 0.2 kilometers

Correct answer: D

Rationale: To convert meters to kilometers, divide the number of meters by 1000, as 1 kilometer is equal to 1000 meters. Therefore, 200 meters is equivalent to 200 / 1000 = 0.2 kilometers. Choices A, B, and C are incorrect because they do not correctly convert meters to kilometers. A provides an answer that would be correct if converting from kilometers to meters. B and C are much larger distances than what 200 meters represent.

4. Where does digestion begin in the digestive system?

• A. Stomach
• B. Mouth
• C. Small intestine
• D. Esophagus

Correct answer: B

Rationale: Digestion begins in the mouth. Mechanical digestion through chewing and chemical digestion through saliva initiate the breakdown of food. Enzymes in saliva start breaking down carbohydrates, marking the beginning of the digestive process. The stomach primarily functions in further breaking down food and mixing it with gastric juices. The small intestine is where most of the digestion and absorption of nutrients occur. The esophagus is a muscular tube that helps move food from the mouth to the stomach, but digestion does not begin there.

5. Select the meaning of the underlined word in the following sentence. What is the prognosis for those accident victims?

• A. Expected outcome
• B. Treatment option
• C. Fabrication
• D. Fabrication

Correct answer: A

Rationale: In this sentence, the word 'prognosis' refers to the expected outcome or forecast for the accident victims. It indicates what is likely to happen in terms of their recovery or overall condition following the accident. Therefore, the correct meaning of the underlined word is the expected outcome, which is option A. Choices B, C, and D are incorrect because 'prognosis' does not refer to a treatment option or fabrication.
