ATI TEAS Science Questions

1. Which term describes a position closer to the center of the body?

Correct answer: B

Rationale: The correct answer is B: Proximal. Proximal is used to describe a position closer to the center of the body. Distal, the incorrect choice, refers to a position farther away from the center. Lateral, another incorrect choice, indicates a position on the side of the body. Medial, also an incorrect option, describes a position towards the middle or midline of the body.

2. What does the term 'colligative property' refer to in solutions?

Correct answer: B

Rationale: Colligative properties are properties of a solution that depend on the concentration of solute particles, regardless of the identity of the solute. These properties include lowering the vapor pressure, elevation of boiling point, depression of freezing point, and osmotic pressure. The concentration of solute particles affects these properties, not the nature, temperature, or pressure of the solution. Therefore, choice B is the correct answer as it accurately reflects the definition of colligative properties. Choices A, C, and D are incorrect because colligative properties are not based on the nature, temperature, or pressure of the solute, but rather on the concentration of solute particles in the solution.

3. What cellular process ensures the accurate transmission of genetic material during cell division?

Correct answer: A

Rationale: Mitosis is the correct answer. Mitosis is the process by which somatic cells divide to produce two identical daughter cells. During mitosis, the genetic material is accurately replicated and distributed to ensure each daughter cell receives a complete set of chromosomes. This process is crucial for growth, repair, and maintenance of multicellular organisms. Meiosis, on the other hand, is the type of cell division that occurs in germ cells to produce gametes (sperm and egg cells), focusing on genetic diversity through recombination and reduction of chromosome number. Replication is the process of copying DNA to produce an identical copy, essential for cell division but not the specific process ensuring accurate genetic material transmission. Transcription involves copying DNA into RNA, crucial for gene expression but not directly related to the accurate transmission of genetic material during cell division.

4. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?

Correct answer: B

Rationale: The correct answer is B: Frequency increases. Frequency and wavelength are inversely proportional in a wave with a constant speed. When the wavelength decreases while the speed remains constant, the frequency must increase to maintain the constant speed of the wave. This relationship is governed by the equation: speed = frequency x wavelength. Choice A is incorrect as frequency increases when wavelength decreases. Choice C is incorrect as the frequency changes in this scenario. Choice D is incorrect as the frequency does not become zero but increases when the wavelength decreases.

5. Which of the following statements is true regarding the ventricles of the heart?

Correct answer: D

Rationale: All of these statements are true regarding the ventricles of the heart. The left ventricle does indeed pump oxygenated blood into the aorta, while the right ventricle pumps deoxygenated blood into the pulmonary trunk. Ventricles are indeed the discharging chambers of the heart, responsible for pumping blood out into the circulatory system. Therefore, as all the statements are accurate, the correct answer is 'All of the above.' Choices A, B, and C are all correct statements about the ventricles, making them incorrect answers in isolation.
