ATI TEAS 7 science review Questions

Question 1 of 5

How is the muscular system benefited by regular exercise?

Correct Answer: B

Rationale: Regular exercise is beneficial for the muscular system by improving muscle strength and endurance. Exercise helps to build and maintain muscle mass, increase muscle strength, and enhance muscle endurance. It does not decrease muscle mass, make muscles less flexible, or increase the risk of muscle tears when done properly. Therefore, the correct answer is improving muscle strength and endurance, as it aligns with the positive effects of regular exercise on the muscular system.

Question 2 of 5

What is the general formula for an alkyl halide?

Correct Answer: C

Rationale: The correct answer is option C, 'CₙH₂ₙ₊₁X.' This is the general formula for an alkyl halide, where X represents a halogen atom (such as fluorine, chlorine, bromine, or iodine), and the hydrocarbon chain is represented by CₙH₂ₙ₊₁. Option A, 'CₙH₂ₙ,' is incorrect because it does not account for the presence of a halogen atom. Option B, 'CₙH₂ₙ₊₂,' is incorrect as it represents an alkene, not an alkyl halide. Option D, 'CₙH₂ₙO,' is also incorrect as it suggests the presence of oxygen, which is not characteristic of alkyl halides.

Question 3 of 5

What is the primary function of the large intestine?

Correct Answer: D

Rationale: The primary function of the large intestine is to absorb water and electrolytes from the indigestible food matter that passes through it. This absorption process aids in the formation of solid waste (feces) before it is excreted from the body. Choices A, B, and C are incorrect because the large intestine does not primarily digest and absorb nutrients, store and mix food, or break down carbohydrates. These functions are primarily carried out by the small intestine.

Question 4 of 5

Which of the following substances is an example of an acidic gas?

Correct Answer: C

Rationale: The correct answer is C, Sulfur dioxide (SO₂). Sulfur dioxide is an acidic gas because when dissolved in water, it forms sulfurous acid, which imparts acidic properties. Nitrogen (N₂), carbon dioxide (CO₂), and oxygen (O₂) are not considered acidic gases. Nitrogen is a neutral gas, carbon dioxide forms a weakly acidic solution when dissolved in water, and oxygen is a neutral gas.

Question 5 of 5

Which respiratory structure is responsible for the production of mucus to trap particles and for the movement of cilia to sweep mucus and trapped particles out of the respiratory tract?

Correct Answer: D

Rationale: The respiratory epithelium is the correct answer because it is the tissue lining the respiratory tract responsible for producing mucus to trap particles and containing cilia that sweep the mucus and trapped particles out of the respiratory tract. The trachea, larynx, and bronchi are all structures within the respiratory system but do not specifically carry out the functions described in the question. The trachea is a passage for air, the larynx is involved in sound production and protecting the airway, and the bronchi are airway passages that branch from the trachea to the lungs. Only the respiratory epithelium fits the description of producing mucus and utilizing cilia for particle removal in the respiratory tract.
