1. What is the scientific name for the common housefly?

Correct answer: A

Rationale: Rationale: - Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. - Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. - Apis mellifera (option C) is the scientific name for the western honeybee. - Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

2. What is the role of the appendix, a small pouch attached to the large intestine?

Correct answer: B

Rationale: While the exact function of the appendix is still debated, it likely houses lymphoid tissue, contributing to the immune system.

3. The liver plays a vital role in digestion. What is one of the main functions of the liver in the digestive system?

Correct answer: C

Rationale: The correct answer is C: 'Storage and processing of nutrients.' The liver is a crucial organ in the digestive system as it performs various functions such as storing nutrients like glucose, vitamins, and minerals, processing nutrients by converting them into usable forms for the body, and regulating their distribution to different parts of the body. While the physical breakdown of food primarily occurs in the mouth and stomach, and the production of digestive enzymes mainly happens in the pancreas and small intestine, the liver's main role is to manage and store the nutrients obtained from the digested food. Therefore, option C is the correct choice for the main function of the liver in the digestive process.

4. What is the term for the first exposure to a specific pathogen, leading to the development of an initial immune response?

Correct answer: A

Rationale: The correct answer is A: 'Primary immune response.' The primary immune response refers to the initial encounter with a specific pathogen, which triggers the immune system to respond by producing antibodies and memory cells. This process lays the foundation for the secondary immune response, which occurs upon subsequent exposure to the same pathogen. The primary immune response is characterized by the lag time in antibody production as the immune system is mobilized to combat the new threat. In contrast, the secondary immune response is faster and more robust due to the presence of memory cells from the primary response. Hypersensitivity reactions involve an exaggerated immune response to an antigen, while immunological tolerance refers to the immune system's ability to recognize self from non-self to prevent autoimmunity.

5. Balance the chemical equation: C4H10 + O2 → CO2 + H2O. What is the coefficient for oxygen?

Correct answer: b

Rationale: The balanced equation is C4H10 + 6O2 → 4CO2 + 5H2O.

6. When choosing a color palette for a presentation, it's best to:

Correct answer: C

Rationale: While both branding consistency and minimalism have their place, presentations benefit from utilizing complementary colors for visual interest and clarity.
