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

Correct answer: C

Rationale: Gold's properties make it ideal for crafting durable and aesthetically pleasing jewelry

2. The human immunodeficiency virus (HIV) targets and destroys which type of immune cell?

Correct answer: A

Rationale: The correct answer is C: Helper T cells. HIV targets and destroys Helper T cells, which are a crucial component of the immune system responsible for coordinating the immune response. Neutrophils and macrophages are also important immune cells, but they are not the primary target of HIV. Memory B cells are responsible for mounting a rapid response upon re-exposure to a pathogen but are not the main target of HIV. Thus, HIV primarily affects Helper T cells, leading to the weakening of the immune system and the development of acquired immunodeficiency syndrome (AIDS).

3. The phrase "think outside the box" encourages readers to:

Correct answer: B

Rationale: The phrase emphasizes unconventional thinking and exploring new approaches.

4. What is the difference between exhalation (expiration) and inhalation (inspiration)?

Correct answer: B

Rationale: Option B is the correct answer because inhalation is the process of breathing in, where the diaphragm and intercostal muscles contract to expand the chest cavity, allowing air to enter the lungs. This air is rich in oxygen, which is essential for cellular respiration. On the other hand, exhalation is the process of breathing out, where the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and air to be expelled from the lungs. This air is depleted of oxygen as it has been used up during cellular respiration. Understanding the difference between inhaling oxygen-rich air and exhaling oxygen-depleted air is crucial for comprehending the respiratory system's function and the exchange of gases in the body.

5. What is the main function of the gallbladder?

Correct answer: A

Rationale: Rationale: The gallbladder is a small organ located beneath the liver that plays a crucial role in the digestive system. Its main function is to store and concentrate bile, a digestive fluid produced by the liver. Bile is released from the gallbladder into the small intestine to help with the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, allowing it to be released in a controlled manner when needed to aid in the digestion of fatty foods. Therefore, option A is the correct answer as it accurately describes the main function of the gallbladder.

6. Which type of symbiosis is where both organisms benefit from the interaction?

Correct answer: A

Rationale: Rationale: Mutualism is a type of symbiosis in which both organisms involved benefit from the interaction. This relationship is characterized by cooperation and mutual support, leading to advantages for both parties. In mutualistic relationships, each organism provides something that the other needs, resulting in a mutually beneficial outcome. Examples of mutualism include the relationship between bees and flowers (pollination) and the partnership between nitrogen-fixing bacteria and leguminous plants.
