TEAS 7 science practice questions

1. Which of the following factors would NOT affect the solubility of a solid solute in a liquid solvent?

Correct answer: B

Rationale: Pressure does not typically affect the solubility of a solid solute in a liquid solvent. Solubility is primarily influenced by factors such as temperature, particle size, and the nature of the solute and solvent. Increasing pressure generally has a minimal effect on the solubility of solids in liquids. The impact of pressure on solubility is more significant for gases in liquids rather than solids in liquids. Therefore, option B is the correct answer. Options A, C, and D directly impact the solubility of a solid solute in a liquid solvent. Temperature affects the solubility as it changes the kinetic energy of particles, particle size can impact the surface area available for interaction between solute and solvent, and the nature of the solute and solvent influences their intermolecular interactions and compatibility.

2. What is the primary organ responsible for filtering urine?

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are the primary organs responsible for filtering urine. They filter waste products and excess substances from the blood to produce urine. Subsequently, urine travels from the kidneys through the ureters to the bladder. The bladder temporarily stores urine until it is expelled from the body through the urethra. The bladder's function is storage, the ureters transport urine, and the urethra is the exit pathway for urine expulsion. Therefore, the kidneys play a vital role in the filtration and production of urine within the urinary system.

3. Which of the following factors can contribute to erectile dysfunction in males?

Correct answer: D

Rationale: Erectile dysfunction can be caused by various factors, including diabetes, cardiovascular disease, and neurological disorders. These conditions can impact blood flow, nerve function, and hormone levels, all crucial for achieving and maintaining an erection. Diabetes can lead to nerve damage and affect blood circulation. Cardiovascular disease can restrict blood flow to the penis. Neurological disorders can interfere with the transmission of nerve signals between the brain and the reproductive organs. Therefore, all the factors mentioned in options A, B, and C can contribute to erectile dysfunction in males.

4. When ice melts, it undergoes a...

Correct answer: B

Rationale: When ice melts, it undergoes a physical change, transitioning from a solid state to a liquid state. This change does not involve altering the chemical composition of the ice, making it a physical change rather than a chemical change, nuclear change, or radioactive decay. Choice A, 'Chemical change,' is incorrect because a chemical change involves a rearrangement of atoms resulting in new substances. Choice C, 'Nuclear change,' is incorrect as it refers to changes in the nucleus of an atom, not the phase transition of ice. Choice D, 'Radioactive decay,' is incorrect as it involves the spontaneous disintegration of an unstable atomic nucleus, which is not the process occurring when ice melts.

5. Which of the following is NOT a function of the endocrine system?

Correct answer: D

Rationale: The endocrine system is responsible for producing hormones that regulate various bodily functions such as growth, metabolism, mood, and more. Facilitating digestion through muscle contractions is primarily the role of the muscular and nervous systems, not the endocrine system. Therefore, option D is the correct answer as it does not align with the functions typically attributed to the endocrine system. Choices A, B, and C are functions that are indeed associated with the endocrine system, making them incorrect answers in the context of this question.
