ATI TEAS Science Questions

1. Which type of reaction typically undergoes condensation reactions?

Correct answer: B

Rationale: The correct answer is 'B: Anabolism.' Anabolic reactions typically involve condensation reactions, where smaller molecules are joined together to form larger molecules by releasing water as a byproduct. This process is fundamental in the synthesis of complex molecules such as proteins and nucleic acids. Choice A, 'Catabolism,' involves decomposition reactions where larger molecules are broken down into smaller ones, which is the opposite of condensation reactions. Choices C and D, 'Exothermic' and 'Endothermic,' refer to the heat exchange during a reaction and are not directly related to the process of condensation reactions.

2. Which of the following is another name for the voice box?

Correct answer: B

Rationale: The correct answer is B, 'Larynx.' The larynx is commonly referred to as the voice box because it plays a crucial role in sound production. It contains vocal cords and functions in speech and singing. Choice A, 'Alveoli,' are small air sacs in the lungs involved in gas exchange. Choice C, 'Trachea,' is the windpipe that connects the larynx to the bronchi. Choice D, 'Pharynx,' is the throat area located behind the mouth and nasal cavity, responsible for the passage of food and air.

3. Which of the following is the neutral subatomic particle found in the nucleus of an atom?

Correct answer: C

Rationale: The correct answer is C, Neutron. Neutrons are subatomic particles found in the nucleus of an atom that have no charge. They have a mass of approximately 1 atomic mass unit (amu). The number of neutrons in an atom's nucleus contributes to the mass number of the atom, which is the total number of protons and neutrons in the nucleus. Choice A, Electron, is incorrect as electrons are negatively charged particles found outside the nucleus. Choice B, Proton, is incorrect as protons are positively charged particles found in the nucleus. Choice D, Positron, is incorrect as positrons are positively charged antiparticles of electrons and are not typically found in the nucleus of an atom.

4. Which of the following salt solutions is most likely to conduct electricity well?

Correct answer: B

Rationale: A concentrated solution of a strong electrolyte is most likely to conduct electricity well. Strong electrolytes completely dissociate into ions in solution, allowing for the flow of electric current. This high concentration of ions in the solution enhances its conductivity, making it a better conductor compared to other options. A saturated solution, although containing dissolved ions, may not have a high enough concentration to conduct electricity effectively. A dilute solution of a weak acid is a poor conductor as weak acids only partially dissociate into ions. A mixture of a neutral compound and water does not contain free ions necessary for conducting electricity.

5. Which of the following brain structures is responsible for emotions, emotional behavior, and motivation?

Correct answer: A

Rationale: The correct answer is the amygdala. The amygdala is a key brain structure involved in processing emotions, emotional behavior, and motivation. It plays a crucial role in fear responses, emotional memories, and social behaviors. The cerebellum (Choice B) is primarily responsible for coordination and balance, not emotions. The hypothalamus (Choice C) regulates basic survival functions like hunger, thirst, and body temperature, but it is not primarily responsible for emotions. The pons (Choice D) is involved in functions such as sleep, respiration, and bladder control, but it is not the main center for emotions, emotional behavior, or motivation.
