1. Which molecule is responsible for storing and providing a quick source of energy during short bursts of intense physical activity, such as weightlifting or sprinting?

• A. ATP (Adenosine Triphosphate)
• B. Glucose
• C. Myoglobin
• D. Lactic Acid

Correct answer: A

Rationale: ATP (Adenosine Triphosphate) is the molecule responsible for storing and providing a quick source of energy during short bursts of intense physical activity like weightlifting or sprinting. ATP is broken down to release energy rapidly when muscles need quick, intense efforts. Glucose is a source of energy but must be converted into ATP before it can be used by muscles. Myoglobin is a protein that stores oxygen in muscle cells and does not directly provide energy. Lactic acid is produced during intense exercise but is not the primary molecule responsible for providing quick energy during short bursts of intense physical activities.

2. Which of the following structures is responsible for gas exchange in the lungs?

• A. Bronchi
• B. Alveoli
• C. Trachea
• D. Diaphragm

Correct answer: B

Rationale: The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. Oxygen from inhaled air diffuses into the blood vessels surrounding the alveoli, while carbon dioxide from the blood is released into the alveoli to be exhaled. The bronchi are air passages that carry air into the lungs but do not participate in gas exchange. The trachea is the windpipe that connects the larynx to the bronchi and serves as an airway for breathing. The diaphragm is a muscle that aids in the breathing process by contracting and relaxing to change the volume of the chest cavity.

3. Which element is used in jewelry due to its malleability and resistance to tarnish?

• A. Iron
• B. Copper
• C. Gold
• D. Silver

Correct answer: C

Rationale: Gold is the correct answer. Gold is a popular choice for jewelry due to its exceptional malleability, allowing it to be easily shaped into intricate designs. Moreover, gold is resistant to tarnish, ensuring the jewelry retains its beauty over time. Iron is not commonly used in jewelry due to its susceptibility to rusting. Copper is also not as popular in jewelry making as gold due to its tendency to tarnish and cause skin discoloration. While silver is used in jewelry, it is more prone to tarnish compared to gold, making it less ideal for long-lasting pieces.

4. Which term refers to the feelings a text creates in the reader?

• A. Tone
• B. Irony
• C. Mood
• D. Theme

Correct answer: C

Rationale: The correct answer is 'Mood.' Mood refers to the atmosphere or emotional setting created by a piece of literary work. It reflects the feelings and emotions evoked in the reader while experiencing the text. 'Tone' (choice A) refers to the attitude of the writer towards the subject or audience, 'Irony' (choice B) involves a contrast between what is expected and what actually occurs, and 'Theme' (choice D) is the central idea or message conveyed by the text.

5. What is the process by which a fertilized egg implants itself in the lining of the uterus?

• A. Fertilization
• B. Implantation
• C. Gestation
• D. Parturition

Correct answer: B

Rationale: Implantation is the correct answer. It is the process where a fertilized egg attaches itself to the lining of the uterus to establish a pregnancy. Fertilization is the initial step where the sperm and egg fuse to form a zygote. Gestation refers to the period of fetal development within the uterus. Parturition is the process of giving birth and is not related to the implantation of the fertilized egg, which occurs earlier in the reproductive process.
