TEAS 7 science practice questions

1. What is the process of a gas changing into a liquid called?

Correct answer: C

Rationale: Condensation is the process where gas particles release energy, slow down, and come together to form a liquid. This phase change occurs when the temperature of the gas decreases, causing the particles to lose energy and transition into the liquid state. In condensation, the gas loses heat energy, leading to a decrease in kinetic energy, which allows the particles to come closer together and form a liquid. This transformation is commonly observed when water vapor in the air cools down and turns into liquid water droplets, seen as dew or fog. Evaporation (choice A) is the opposite process where a liquid changes into a gas. Boiling (choice B) is the rapid phase change from liquid to gas that occurs at a specific temperature. Sublimation (choice D) is the direct transition of a substance from the solid phase to the gas phase without passing through the liquid phase.

2. Which of the following structures acts like a funnel by delivering urine from the millions of collecting tubules to the ureters?

Correct answer: A

Rationale: The correct answer is A: The renal pelvis. The renal pelvis serves as a reservoir for urine collected from the kidney's numerous collecting tubules, funneling it into the ureters for transport to the bladder. The renal cortex is the outer region of the kidney involved in filtration, while the renal medulla is the inner region responsible for concentrating urine. Bowman's capsule is part of the nephron and is involved in the initial filtration of blood in the kidney, not in funneling urine to the ureters.

3. Which of the following describes a responsibility of the integumentary system?

Correct answer: B

Rationale: The correct responsibility of the integumentary system is to act as a barrier that blocks pathogens from entering the body, thus helping to prevent diseases and infections. This function serves as the first line of defense for the body against external threats. Choices A, C, and D are incorrect. Choice A is a function of the circulatory system, not the integumentary system. Choice C relates to the lymphatic system, not the integumentary system. Choice D involves the endocrine system, not the integumentary system.

4. Differentiate between genotype and phenotype in the context of gene expression.

Correct answer: B

Rationale: - Genotype refers to the genetic makeup of an organism, including all the genes and alleles it possesses. - Phenotype, on the other hand, refers to the observable physical characteristics or traits of an organism, which result from the interaction between its genotype and the environment. - While genotype represents the genetic potential or range of traits that an organism can express, phenotype reflects the actual expression of specific traits. - Therefore, option B correctly captures the distinction between genotype and phenotype in the context of gene expression.

5. What is the scientific term for inflammation of the bronchi, often associated with a cough and mucus production?

Correct answer: B

Rationale: Bronchitis is the correct answer. It is the inflammation of the bronchi, which are the air passages in the lungs. Bronchitis typically presents with symptoms such as a persistent cough, mucus production, and sometimes difficulty breathing. Pneumonia, on the other hand, is an infection that causes inflammation in the air sacs of the lungs, not specifically the bronchi. Emphysema is a chronic lung condition characterized by the gradual destruction of the air sacs in the lungs, resulting in breathing difficulties. Pleurisy refers to inflammation of the pleura, the lining around the lungs and chest cavity, causing chest pain when breathing or coughing.
