ATI TEAS 7 science review Questions

Question 1 of 5

Which of the following is a strong acid?

Correct Answer: B

Rationale: Hydrochloric acid (HCl) is a strong acid because it completely ionizes in water to produce hydrogen ions, leading to a high concentration of H⁺ ions in solution. This characteristic makes it a strong acid. Acetic acid (CH₃COOH), citric acid, and carbonic acid (H₂CO₃) are weak acids as they only partially ionize in water, resulting in a lower concentration of H⁺ ions compared to strong acids. Therefore, hydrochloric acid is the correct choice as a strong acid.

Question 2 of 5

What is the term for the reaction between an acid and a base to produce water and a salt?

Correct Answer: B

Rationale: Neutralization is the correct term for the reaction between an acid and a base to produce water and a salt. During neutralization, the hydrogen ions from the acid react with the hydroxide ions from the base to form water, and the remaining ions combine to form a salt. Combustion involves a reaction with oxygen, oxidation is the loss of electrons, and decomposition is the breakdown of a compound into simpler substances. These processes do not accurately describe the reaction between an acid and a base to produce water and a salt.

Question 3 of 5

What is the process of breaking down lipids into fatty acids and glycerol called?

Correct Answer: A

Rationale: - Lipolysis is indeed the correct answer. It is the process of breaking down lipids (fats) into fatty acids and glycerol. This process occurs in adipose tissue and is important for releasing stored energy in the form of fatty acids. - Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources like amino acids and glycerol, not breaking down lipids. - The Krebs cycle (also known as the citric acid cycle) is a series of chemical reactions that occur in the mitochondria to generate energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. - Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced through the transfer of electrons in the electron transport chain. It is not specifically related to the breakdown of lipids into fatty acids and glycerol.

Question 4 of 5

Identify the organ responsible for blood filtration.

Correct Answer: B

Rationale: The correct answer is B: Kidneys. The kidneys are the organs responsible for blood filtration in the human body. They filter waste products and excess substances from the blood to produce urine. The liver is primarily involved in detoxification and metabolism, the spleen functions in immune responses and blood storage, and the pancreas aids in digestion and blood sugar regulation. Therefore, choices A, C, and D are incorrect as they do not primarily serve the function of blood filtration.

Question 5 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.
