Question 1 of 5

What summarizes a change that occurs as solids transition into liquids?

Correct Answer: A

Rationale: The correct answer is A. When solids transition into liquids, particles become less ordered. In a solid state, particles are arranged in a fixed, orderly pattern due to strong intermolecular forces. As the solid transitions into a liquid, these forces weaken, allowing the particles more freedom of movement. Consequently, the particles become less ordered in a liquid compared to a solid, where they have more mobility and are not bound in a fixed structure.

Question 2 of 5

The triple point of a substance is the temperature and pressure at which the substance exists as which of the following?

Correct Answer: C

Rationale: The triple point is a specific condition where a substance can exist simultaneously in all three phases: solid, liquid, and gas. The other options do not accurately describe this state.

Question 3 of 5

Which of the following substances is excreted by the sweat glands in response to the breakdown of proteins and the formation of ammonia?

Correct Answer: C

Rationale: The correct answer is Urea. Sweat glands excrete urea in response to the breakdown of proteins and the formation of ammonia. Urea is a waste product formed in the liver by the breakdown of amino acids. It is then excreted by the kidneys in urine and by sweat glands through perspiration. Urea plays a vital role in the excretory process by helping eliminate nitrogenous wastes from the body and maintaining proper physiological balance.

Question 4 of 5

Which of the following is used to determine a person's DNA sequence?

Correct Answer: D

Rationale: Genes are the correct choice for determining a person's DNA sequence. Genes carry genetic information that dictates various traits and characteristics in individuals. A person's unique DNA sequence is determined by the specific arrangement of nucleotides within their genes. Scientists can analyze genes to decode the DNA sequence that represents an individual's genetic composition.

Question 5 of 5

What is the function of sodium bicarbonate released by the pancreas?

Correct Answer: A

Rationale: The correct answer is A because sodium bicarbonate released by the pancreas functions by neutralizing the acidity of chyme in the small intestine. This action helps to create a more alkaline environment, which is crucial for the activity of pancreatic enzymes and the absorption of nutrients. Option B is incorrect as sodium bicarbonate itself does not stimulate a protease to digest carbonates. Option C is incorrect as sodium bicarbonate does not inhibit peristalsis; instead, it aids in digestion. Option D is incorrect as sodium bicarbonate does not directly stimulate the protease but rather helps in maintaining the optimal pH for enzyme activity.
