Question 2 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 3 of 5

What is the primary outcome of using a catalyst in a chemical reaction?

Correct Answer: C

Rationale: The primary outcome of using a catalyst in a chemical reaction is to accelerate the reaction and complete it in a shorter timeframe. A catalyst functions by lowering the activation energy required for the reaction to occur, thereby speeding up the process without altering the amount of heat energy released, the yield of the product, or the nature of the final product. This acceleration makes the reaction more efficient by facilitating the conversion of reactants to products in a more rapid manner.

Question 4 of 5

In a phase diagram, what term is used for a substance held at a temperature and pressure where solid, liquid, and gaseous states of a substance exist simultaneously?

Correct Answer: B

Rationale: The point described in the question is called the triple point. At the triple point, all three phases of a substance (solid, liquid, and gas) coexist in equilibrium. The critical temperature is the highest temperature at which a distinct liquid phase can form, while absolute zero is the lowest possible temperature. The critical point is the point on a phase diagram that represents the highest temperature and pressure at which a distinct liquid and gas phase can coexist. Therefore, the correct answer is the triple point, where all three phases coexist.

Question 5 of 5

What is a common cause of a tsunami?

Correct Answer: A

Rationale: Earthquakes are a common cause of tsunamis. When an earthquake occurs under the ocean, it can displace a large volume of water, triggering a series of powerful waves known as a tsunami. Sunspot activity, lightning strikes, and flooding do not directly cause tsunamis. Therefore, the correct answer is earthquakes, as they are the primary geological event that leads to the formation of tsunamis.
