Anatomy

1. Which vitamin requires intrinsic factor from the stomach for proper absorption?

Correct answer: D

Rationale: The correct answer is D, Vitamin B12. Vitamin B12 requires intrinsic factor, a glycoprotein produced by the parietal cells in the stomach, for proper absorption in the small intestine. Intrinsic factor binds to B12 and facilitates its absorption in the ileum. Without intrinsic factor, the body cannot effectively absorb Vitamin B12, leading to deficiencies and various health issues. Vitamins A, C, and D do not require intrinsic factor for absorption and have different mechanisms for uptake and utilization within the body.

2. What characteristic unites all organisms in the kingdom Animalia?

Correct answer: A

Rationale: Rationale: A) Multicellularity and heterotrophy: This is the correct answer because all organisms in the kingdom Animalia are multicellular (composed of multiple cells) and exhibit heterotrophy (obtain nutrients by consuming other organisms). B) Unicellular nature: This is incorrect because organisms in the kingdom Animalia are multicellular, not unicellular. C) Photosynthesis: This is incorrect because organisms in the kingdom Animalia do not perform photosynthesis; they are heterotrophs that obtain nutrients by consuming other organisms. D) Cell walls made of chitin: This is incorrect because organisms in the kingdom Animalia do not have cell walls made of chitin. Chitin is a structural polysaccharide found in the cell walls of fungi, not animals.

3. Identify the incorrect usage of punctuation in the following sentence: "The children, eager to play, ran outside. It was a beautiful day."

Correct answer: C

Rationale: The two sentences are independent clauses and should be separated by a semicolon or period, not a comma.

4. A satellite orbits the Earth at constant speed. Which force is responsible for its circular motion?

Correct answer: A

Rationale: This force acts towards the Earth's center, providing the centripetal force required for the satellite to move in a circle.

5. Which of the following is the smallest part of an element that can still be recognized as that element?

Correct answer: D

Rationale: An atom is the smallest unit of matter that retains the chemical properties of an element. It is composed of a nucleus containing protons and neutrons, and electrons that orbit the nucleus. The number of protons in the nucleus determines the atomic number of the element, and the number of neutrons determines the isotope of the element.

6. Which of the following statements about prions is TRUE?

Correct answer: A

Rationale: Rationale: A) This statement is true. Prions are infectious agents composed entirely of protein, lacking nucleic acids such as DNA or RNA. They are known for causing neurodegenerative diseases in animals and humans. B) This statement is false. Prions are not easily destroyed by common disinfectants due to their unique structure and resistance to conventional sterilization methods. C) This statement is false. Prions are not a type of antibiotic. They are a distinct class of infectious agents. D) This statement is false. Prions are not live organisms but rather misfolded proteins that can induce abnormal folding in normal proteins, leading to disease.
