TEAS Test 7 science Questions
Question 1 of 5
Which kingdom primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose?
Correct Answer: C
Rationale: A) Animalia consists of multicellular organisms that lack cell walls and are heterotrophic. Therefore, it does not primarily consist of photosynthetic organisms with cell walls made of cellulose. B) Fungi are multicellular organisms with cell walls made of chitin and are heterotrophic, so they do not fit the description. C) Plantae primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose. This accurately describes plants. D) Protista is a diverse kingdom that includes unicellular and multicellular organisms with varying characteristics, but it does not primarily consist of multicellular, photosynthetic organisms with cell walls made of cellulose.
Question 2 of 5
Which structure in the respiratory system serves as a passageway for both air and food, with a flap-like structure that prevents food from entering the trachea during swallowing?
Correct Answer: B
Rationale: The pharynx is the correct answer. The pharynx is a structure in the respiratory system that serves as a passageway for both air and food. It contains a flap-like structure called the epiglottis, which prevents food from entering the trachea during swallowing by covering the opening to the trachea. The larynx, although important in the respiratory system, is located below the pharynx and contains the vocal cords. The trachea is a tube that carries air to and from the lungs, while the bronchi are the two main branches that lead from the trachea into the lungs.
Question 3 of 5
What is the process of cells restoring damaged or lost tissues called?
Correct Answer: D
Rationale: Rationale: A) Cell division refers to the process by which a cell divides into two daughter cells. B) Cell differentiation is the process by which cells become specialized for specific functions. C) Cell growth is the increase in cell size or number. D) Cell regeneration is the process of cells restoring damaged or lost tissues by replacing or repairing the damaged cells. This process is essential for healing wounds and maintaining tissue integrity.
Question 4 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 5 of 5
Scoliosis is a condition characterized by abnormal lateral curvature of the spine. Which part of the spine is most commonly affected?
Correct Answer: B
Rationale: Scoliosis most commonly affects the thoracic spine, which is the upper back region. While scoliosis can potentially affect any part of the spine, the thoracic spine is the most frequently involved area. This region is more commonly affected due to the natural structural curves of the spine and the biomechanics of the thoracic area. The cervical spine (neck) and lumbar spine (lower back) can also be affected by scoliosis, but the thoracic spine is the primary area of involvement in most cases. Therefore, the correct answer is B, as it is the part of the spine most commonly affected by scoliosis.
