ATI TEAS Science Questions

1. Which type of tissue connects muscles to bones?

Correct answer: B

Rationale: The correct answer is B: Tendons. Tendons connect muscles to bones, not bones to muscles. They play a crucial role in transmitting the force generated by muscles to move bones, enabling movement. Ligaments (choice A) connect bones to bones, providing stability to joints. Cartilage (choice C) is a connective tissue found in joints, providing cushioning and flexibility. Muscles (choice D) are responsible for generating force through contraction but do not directly connect muscles to bones.

2. Which type of joint allows for the widest range of motion, similar to the shoulder joint?

Correct answer: B

Rationale: The correct answer is B: Ball-and-socket joint. Ball-and-socket joints, like the shoulder joint, allow for the widest range of motion in multiple directions. This type of joint consists of a rounded bone (the 'ball') fitting into a cup-like socket, enabling movements such as flexion, extension, abduction, adduction, and rotation. Choice A, Hinge joint, allows movement in one plane, like a door hinge, and does not offer the same range of motion as a ball-and-socket joint. Choice C, Gliding joint, permits limited motion in various directions but not as wide as a ball-and-socket joint. Choice D, Fixed joint, does not allow any motion as it is immovable, unlike the shoulder joint which is highly mobile.

3. What is the most powerful stimulus for breathing in a healthy person?

Correct answer: C

Rationale: The correct answer is an increase in CO2. In a healthy individual, the primary drive to breathe is regulated by the levels of carbon dioxide (CO2) in the blood. When CO2 levels increase, it triggers the body to increase the rate and depth of breathing to eliminate excess CO2 and restore the balance. This response is more powerful than other stimuli such as acidosis, alkalosis, or loss of oxygen. While acidosis and alkalosis can affect breathing, an increase in CO2 has a more direct and immediate impact. Loss of oxygen (hypoxia) is a potent stimulus, but the body's response to increased CO2 levels is generally more pronounced and immediate in healthy individuals.

4. Who is credited with the discovery of nuclear fission?

Correct answer: C

Rationale: Enrico Fermi is credited with the discovery of nuclear fission. In 1934, Fermi bombarded uranium with neutrons, leading to the splitting of the uranium nucleus and the release of energy. This groundbreaking discovery laid the foundation for the development of nuclear power and weapons. Marie Curie is known for her pioneering research on radioactivity, but she did not discover nuclear fission. Albert Einstein made significant contributions to physics, including the theory of relativity, but he was not credited with the discovery of nuclear fission. Ernest Rutherford conducted the famous gold foil experiment and made contributions to the understanding of the atom's structure, but he did not discover nuclear fission.

5. What are Mendel's laws?

Correct answer: B

Rationale: The correct answer is B. Mendel's laws consist of the law of segregation, which states that each parent passes one allele for each trait, and the law of independent assortment, which explains that genes for different traits are inherited independently. Choice A is incorrect because 'law of expression' is not one of Mendel's laws. Choice C is incorrect because 'law of dominance' and 'law of recessiveness' do not represent the two main laws proposed by Mendel. Choice D is incorrect because 'law of mutation' and 'law of crossing over' are not part of Mendel's original laws.
