TEAS Test 7 science Questions

Question 1 of 5

Which of the following is NOT a part of a plant cell?

Correct Answer: D

Rationale: A) Cell wall: This is a structure found in plant cells that provides support and protection. B) Plasma membrane: Also known as the cell membrane, it surrounds the cell and regulates the passage of substances in and out of the cell. C) Vacuole: This is a storage organelle found in plant cells that stores water, nutrients, and waste products. D) Mitochondria: Mitochondria are membrane-bound organelles found in both plant and animal cells. They are responsible for producing energy in the form of ATP through cellular respiration. Therefore, the correct answer is D) Mitochondria, as it is a part of a plant cell.

Question 2 of 5

What does the term 'dilution' refer to in a solution?

Correct Answer: A

Rationale: The term 'dilution' in a solution refers to adding more solvent to decrease the concentration of the solution. Dilution involves reducing the concentration of the solute in the solution by increasing the amount of solvent. Choice B is incorrect because adding more solute would increase the concentration, not decrease it. Choices C and D are also incorrect as they relate to factors affecting solubility, not dilution specifically. Therefore, choice A is the correct answer as it accurately defines the process of dilution in a solution.

Question 3 of 5

Which type of energy is possessed by an object due to its position or configuration?

Correct Answer: C

Rationale: Potential energy is the energy that an object possesses due to its position or configuration. It is considered stored energy that can be converted into other forms of energy to do work. When an object is lifted against gravity or compressed, it gains potential energy. Kinetic energy, the incorrect choice A, is the energy of motion possessed by an object. Thermal energy, the incorrect choice B, is related to the temperature of an object due to the motion of its particles. Electrical energy, the incorrect choice D, is related to the flow of electric charge in a circuit or system. Therefore, the correct answer is potential energy as it is associated with an object's position or configuration.

Question 4 of 5

Which of the following substances is NOT typically found in healthy urine?

Correct Answer: B

Rationale: Glucose is not typically found in healthy urine because the kidneys usually filter glucose from the blood and reabsorb it back into the bloodstream. The presence of glucose in urine, known as glucosuria, is usually indicative of diabetes or other medical conditions affecting glucose regulation. On the other hand, urea, creatinine, and electrolytes are commonly present in healthy urine as byproducts of metabolism and electrolyte balance. Urea is a waste product of protein metabolism, creatinine is a waste product of muscle metabolism, and electrolytes are essential for various physiological functions in the body. Therefore, choices A, C, and D are typically found in healthy urine, making them incorrect answers.

Question 5 of 5

Which of the following is an example of aseptic technique?

Correct Answer: A

Rationale: Aseptic technique refers to practices that help prevent the introduction of harmful microorganisms into a sterile environment. Washing hands with soap and water before surgery is an essential component of aseptic technique as it helps reduce the number of microorganisms on the hands, decreasing the risk of introducing pathogens into the surgical site. Coughing into your elbow is a good hygiene practice to prevent the spread of respiratory infections but is not specifically related to aseptic technique. Sharing a stethoscope without cleaning can introduce microorganisms from one patient to another, compromising aseptic conditions. Leaving a wound dressing exposed can lead to contamination and infection, which is contrary to aseptic technique.
