ATI TEAS Science Questions

1. What is the muscular tube that connects the outer surface to the cervix in a woman's birth canal referred to as?

Correct answer: C

Rationale: The correct answer is C, 'The vagina.' The muscular tube that connects the outer surface to the cervix in a woman's birth canal is called the vagina. The vagina serves as the passageway for menstrual flow, sexual intercourse, and childbirth. The cervix, not the uterus, connects the vagina to the uterus. The ovaries, on the other hand, are the organs responsible for producing eggs and female hormones, but they are not the muscular tube connecting the outer surface to the cervix in the birth canal.

2. Which property of a substance refers to its ability to be stretched into thin wires without breaking?

Correct answer: C

Rationale: Ductility is the property of a substance that allows it to be stretched into thin wires without breaking. This property is distinct from the other options provided. Conductivity refers to the ability to conduct electricity or heat, viscosity refers to a liquid's resistance to flow, and malleability refers to the ability of a substance to be hammered or rolled into thin sheets. Therefore, the correct answer is 'Ductility.'

3. Which of the following is an example of adaptive immunity?

Correct answer: C

Rationale: Antibodies are produced by the adaptive immune system in response to specific antigens. They play a crucial role in targeting and neutralizing pathogens, providing long-lasting immunity against future infections. In contrast, options A (inflammation), B (fever), and D (phagocytosis) are examples of innate immunity, the body's immediate, non-specific defense mechanisms. Inflammation is a response to tissue damage, fever is a systemic response to infection, and phagocytosis is a process where cells engulf and digest pathogens, all part of the innate immune response.

4. What is the primary function of the liver related to digestion?

Correct answer: D

Rationale: The primary function of the liver related to digestion is to filter and detoxify byproducts of digestion, including toxins and metabolic waste products. While the liver does produce bile and convert waste ammonia into urea, these functions are not directly related to digestion. Storing bile is mainly done by the gallbladder, not the liver.

5. What is the significance of a healthy gut microbiome?

Correct answer: B

Rationale: A healthy gut microbiome plays a crucial role in boosting the immune system by defending against harmful pathogens, synthesizing essential nutrients like vitamins, aiding in the digestion of certain foods, and maintaining overall gut health. While the gut microbiome does contribute to the breakdown of complex carbohydrates and regulation of appetite, its significance extends beyond these functions to include immune support and nutrient synthesis. Choice A, production of digestive enzymes, is not the primary significance of a healthy gut microbiome. Choice C is a function related to the gut microbiome but is not the sole significance. Choice D, regulation of appetite, is important but not as central as the immune system support and nutrient synthesis provided by a healthy gut microbiome.
