ATI TEAS Science Questions

1. Which organ's primary role is the production of bile and other metabolic functions such as blood sugar regulation and detoxification?

Correct answer: C

Rationale: The correct answer is the liver. The liver is responsible for producing bile, regulating blood sugar levels, and detoxifying the blood. Bile produced by the liver is stored in the gallbladder. The pancreas primarily functions in digestion by producing enzymes and insulin, while the stomach is mainly involved in breaking down food through the secretion of gastric juices.

2. What is the term for a group of organisms with the same genetic makeup?

Correct answer: B

Rationale: In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. A population (option A) refers to a group of individuals of the same species living in the same area. Genotype (option C) refers to the genetic makeup of an individual organism. Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. Therefore, the most appropriate choice for the question is 'Clone,' as it specifically refers to organisms with the same genetic makeup.

3. What is the unit of measurement for density?

Correct answer: A

Rationale: Density is defined as mass per unit volume. The most commonly used unit for density in the metric system is grams per liter (g/L). Kilograms per cubic meter (kg/m³) is also a common unit for density, but grams per liter is more frequently used in everyday measurements. Pounds per square inch (psi) is a unit of pressure, not density. Newtons per meter (N/m) is a unit of force per unit length, not density.

4. Which of the following structures can serve as a passageway for both food and air?

Correct answer: B

Rationale: The correct answer is the Laryngopharynx. It is a common passageway for both food and air. The Esophagus (Choice A) is solely for transporting food from the throat to the stomach. The Nasopharynx (Choice C) is primarily involved in the passage of air. The Trachea (Choice D) is responsible for conducting air to and from the lungs and does not play a role in the passage of food.

5. Which organ produces insulin and glucagon?

Correct answer: D

Rationale: The correct answer is D, Pancreas. The pancreas is the organ responsible for producing the hormones insulin and glucagon. Insulin functions to lower blood sugar levels by facilitating the uptake of glucose by cells for energy production. On the other hand, glucagon works to raise blood sugar levels by prompting the liver to release stored glucose into the bloodstream. The pancreas is a vital organ in the endocrine system, playing a crucial role in maintaining appropriate blood sugar levels in the body. Choices A, B, and C are incorrect as the salivary glands produce saliva, the liver is involved in various metabolic functions, and the gallbladder stores bile produced by the liver, but none of these organs produce insulin and glucagon.
