TEAS 7 science practice questions

1. According to the Cahn-Ingold-Prelog (CIP) ranking system, which functional group has the highest priority?

Correct answer: C

Rationale: In the Cahn-Ingold-Prelog (CIP) ranking system, functional groups are prioritized based on the atomic number of the atoms directly attached to the functional group. Carboxylic acid (COOH) holds the highest priority as the carbon atom is directly bonded to two oxygen atoms, which have higher atomic numbers compared to carbon, hydrogen, or nitrogen. The higher the atomic number of the attached atoms, the higher the priority of the functional group in the CIP ranking system. Therefore, choices A, B, and D are incorrect as they have lower atomic numbers in the atoms directly attached to them, making them lower in priority according to the CIP system.

2. Which of the following lobes of the brain is responsible for processing auditory sounds?

Correct answer: D

Rationale: The correct answer is D: Temporal. The temporal lobe of the brain is responsible for processing auditory sounds. It is also involved in memory and language functions. Choice A, Frontal lobe, is primarily associated with functions such as decision-making, problem-solving, and planning. Choice B, Occipital lobe, is responsible for processing visual information. Choice C, Parietal lobe, is involved in processing sensory information like touch, temperature, and pressure. Therefore, the temporal lobe is the specific lobe responsible for processing auditory information, making it the correct answer.

3. What is the function of the Golgi apparatus?

Correct answer: B

Rationale: The Golgi apparatus plays a crucial role in the cell by packaging and modifying proteins and lipids synthesized by the endoplasmic reticulum. These proteins and lipids are then transported to their final destinations within the cell or outside of it. The Golgi apparatus does not break down and recycle cellular waste, generate energy through cellular respiration, or translate DNA into proteins. Its primary function is related to processing and sorting molecules for cellular use.

4. What is the most common cause of hospital-acquired infections (HAIs)?

Correct answer: B

Rationale: Hospital-acquired infections (HAIs), also known as nosocomial infections, are infections that patients acquire during the course of receiving treatment in a healthcare facility. Among the options provided, bacteria are the most common cause of HAIs. Bacteria such as Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa are known to cause a wide range of infections in healthcare settings. While viruses, fungi, and parasites can also cause HAIs, bacteria are the most prevalent and significant pathogens responsible for these infections. Proper infection control measures, including hand hygiene, environmental cleaning, and antimicrobial stewardship, are essential in preventing and controlling HAIs caused by bacteria.

5. Neurons, the functional units of the nervous system, belong to which tissue type?

Correct answer: D

Rationale: Neurons are the functional units of the nervous system and are specialized cells that transmit nerve impulses. They belong to nervous tissue, which is the primary tissue type of the nervous system. Nervous tissue is composed of neurons and supporting cells called neuroglia. Choices A, B, and C are incorrect because epithelial tissue functions mainly in covering and lining body surfaces, connective tissue provides support and structure, and muscle tissue is responsible for movement. Neurons, being the basic functional units of the nervous system, are specifically classified under nervous tissue.
