ATI TEAS Science Questions
1. Which of the following is not a component of blood?
- A. Red blood cells
- B. White blood cells
- C. Platelets
- D. Cartilage
Correct answer: D
Rationale: The correct answer is D: Cartilage. Cartilage is not a component of blood. Blood primarily consists of red blood cells, white blood cells, and platelets. Red blood cells are responsible for carrying oxygen, white blood cells are part of the immune system, and platelets are essential for blood clotting. Cartilage, on the other hand, is a type of connective tissue found in various parts of the body, such as the joints and nose, but it is not present in the blood. Therefore, choices A, B, and C are incorrect as they are components of blood, while choice D, Cartilage, is the correct answer as it is not a component of blood.
2. What is the estimated total amount of money the roommates used to purchase the gift?
- A. $34
- B. $35
- C. $36
- D. $37
Correct answer: C
Rationale: To find the total amount spent by the roommates, you need to add up the individual amounts each roommate contributed. Anna contributed $18, Liz contributed $12, and Jane contributed $6. Adding these amounts together gives us $18 + $12 + $6 = $36. Therefore, the correct answer is $36. Option A ($34), Option B ($35), and Option D ($37) are incorrect as they do not match the correct calculation of the total amount spent by the roommates.
3. What is the main role of the large intestine in digestion?
- A. Absorbing proteins
- B. Absorbing carbohydrates
- C. Absorbing fats
- D. Absorbing water
Correct answer: D
Rationale: The main role of the large intestine in digestion is to absorb water. When food reaches the large intestine, most nutrients have already been absorbed by the small intestine. In the large intestine, water is absorbed from the remaining undigested food, helping to form solid waste (feces). Absorbing proteins, carbohydrates, or fats primarily occurs in the small intestine, not in the large intestine. Therefore, options A, B, and C are incorrect.
4. What is the term for a microorganism that lives on or in the human body and normally causes no disease or harm?
- A. Bacteria
- B. Commensal Microorganism
- C. Microorganism
- D. Host
Correct answer: B
Rationale: The correct term for a microorganism that lives on or in the human body without causing harm is a commensal microorganism. Commensal microorganisms coexist with the host without causing disease or harm. Choice A, 'Bacteria,' is too broad as not all bacteria are harmless in the body. Choice C, 'Microorganism,' is a general term and does not specifically refer to the harmless nature of the organism. Choice D, 'Host,' refers to the organism harboring the microorganism, not the microorganism itself.
5. Which of the following best expresses the meaning of "intelligence (instinct)" in the context of this passage?
- A. Instinct is synonymous with intelligence in the passage.
- B. Intelligence and instinct are not clearly distinct in the context.
- C. Instinct is a natural ability to perform actions without learned behavior.
- D. Instinct refers to an animal's natural survival mechanism.
Correct answer: A
Rationale: Instinct refers to natural, unlearned behaviors, particularly in survival and reproduction.
