ATI TEAS Science Questions

1. What is the monomer for nucleic acids?

Correct answer: A

Rationale: The correct answer is A: Nucleotide. Nucleotides are indeed the monomers that make up nucleic acids like DNA and RNA. They consist of a sugar molecule, a phosphate group, and a nitrogenous base. Amino acids are the monomers of proteins, not nucleic acids. While the phosphate group is a component of nucleotides, it is not the sole monomer. Ribosome is a cellular organelle involved in protein synthesis and is not a monomer for nucleic acids.

2. In the body, muscle tissue is involved in which of the following functions?

Correct answer: D

Rationale: Muscle tissue serves multiple functions in the body, including the generation of body heat, joint stabilization, and maintenance of posture. These functions are essential for movement, stability, and overall bodily functions. The correct answer is 'All of the above' because muscle tissue plays a key role in each of these vital functions. The generation of body heat occurs through muscle activity, joint stabilization is achieved by muscles surrounding joints, and maintaining posture involves muscle contraction to support the body's position. Therefore, all the listed functions are interconnected and rely on the proper functioning of muscle tissue.

3. What is the unit of measurement for force in the International System of Units (SI)?

Correct answer: A

Rationale: The unit of measurement for force in the International System of Units (SI) is the Newton (N). One Newton is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. Therefore, the correct answer is Newton (N). The other choices are incorrect because: B) Kilogram (kg) is a unit of mass, not force; C) Joule (J) is a unit of energy; D) Meter per second squared (m/s²) is a unit of acceleration, not force.

4. What is the primary function of the large intestine?

Correct answer: C

Rationale: The large intestine's primary function is to absorb water from undigested food remnants and compact them into solid waste (feces). This process helps regulate hydration levels in the body and aids in waste elimination. Choices A, B, and D are incorrect. Absorbing digested material into the blood is mainly done in the small intestine, nutrient processing and metabolizing occur in various parts of the digestive system, and bile production and storage are functions of the liver and gallbladder, not the large intestine.

5. What happens to the internal energy of a system when it performs work on its surroundings?

Correct answer: B

Rationale: When a system performs work on its surroundings, it loses energy in the form of work done. This results in a decrease in the internal energy of the system. Work done by the system is considered as negative work, leading to a decrease in internal energy. Therefore, the correct answer is that the internal energy decreases when a system performs work on its surroundings. Choice A is incorrect as the internal energy decreases, not increases. Choice C is incorrect because the internal energy changes due to the work done. Choice D is incorrect because the information provided is sufficient to determine the change in internal energy.
