TEAS Practice Test Science Questions

Question 1 of 5

What type of joint is found in the shoulder and hip, allowing for a wide range of motion?

Correct Answer: B

Rationale: The correct answer is B: Ball-and-socket joint. This joint allows for a wide range of motion due to its structure where a rounded end of one bone fits into a cup-like socket of another bone. The shoulder and hip joints are prime examples of ball-and-socket joints, enabling movements in multiple directions. A: Hinge joints, like the elbow, allow movement in one plane. C: Pivot joints, like the neck, allow rotational movement. D: Saddle joints, like the thumb, allow for various movements but not the same wide range as ball-and-socket joints.

Question 2 of 5

Which of the following are properties of a liquid?

Correct Answer: D

Rationale: The correct answer is D: Takes shape of container. Liquids do not have a fixed shape but take the shape of the container they are in due to the particles being able to flow and move past each other. Choice A is incorrect as liquids have moderate atomic attraction, not high. Choice B is incorrect as liquids have a fixed volume but not a fixed shape. Choice C is incorrect as liquids can have varying pressures depending on the conditions.

Question 3 of 5

Which of the following immune cells are part of the innate immune response?

Correct Answer: C

Rationale: The correct answer is C: Natural Killer cells. Natural Killer cells are part of the innate immune response as they can recognize and eliminate infected or abnormal cells without prior exposure. B-cells and cytotoxic T-cells are part of the adaptive immune response, requiring specific antigens to respond. Antigen-Presenting Cells play a crucial role in initiating the adaptive immune response by presenting antigens to T-cells. Therefore, Natural Killer cells are the only cells listed that belong to the innate immune response.

Question 4 of 5

Following the scientific method, which steps would be done before gathering qualitative data?

Correct Answer: B

Rationale: Correct Answer: B (Define the problem) Rationale: 1. Defining the problem is the first step in the scientific method to identify the research focus. 2. It helps in formulating specific research questions and objectives. 3. Before gathering qualitative data, having a clear problem statement is essential to guide the research process. Incorrect Choices: A: Communicating with a scientific journal is not a step in the scientific method, but rather a later stage after conducting research. C: Developing a hypothesis comes after defining the problem to propose a possible explanation for the research question. D: Categorizing data for statistical analysis is done after data collection, not before gathering qualitative data.

Question 5 of 5

Which neuromuscular system controls voluntary movement?

Correct Answer: B

Rationale: The correct answer is B: Somatic. The somatic nervous system controls voluntary movements by sending signals from the brain to skeletal muscles. It is under conscious control. Autonomic (A), sympathetic (C), and parasympathetic (D) systems control involuntary functions like heart rate and digestion. These systems operate without conscious effort, making them unsuitable for controlling voluntary movements.
